* Specify the location for the agent PKCS#12 file so we don't have to move it.Rob Crittenden2013-05-061-3/+1
| | | | | | | Dogtag 10.0.2 changed the default location for this file from /root/.pki to /root/.dogtag which broke our install. https://fedorahosted.org/freeipa/ticket/3599
* Handle socket.gethostbyaddr() exceptions when verifying hostnames.Rob Crittenden2013-04-241-0/+2
| | | | | | | | | | Log any socket exceptions raised and let the process continue. This failure isn't a show-stopper. Other checks past this will catch any other problems. This was seen when /etc/hosts and /etc/resolv.conf were both empty. https://fedorahosted.org/freeipa/ticket/3581

* Enhance ipa-adtrust-install for domains with multiple IPA serverAlexander Bokovoy2013-04-021-8/+36
| | | | | | | | | | As described on http://www.freeipa.org/page/V3/MultipleTrustServers, notice if FreeIPA server is a replica and adtrust agents contains members corresponding to the cifs/ services from replication partners. Only these servers will be advertised as SMB domain controllers https://fedorahosted.org/freeipa/ticket/2189
* Add logging to join commandTomas Babej2013-03-251-6/+20
| | | | | | | | | The following is mentioned in the log now: - existence of host entry (if it already does exist) - missing krbprincipalname and its new value (if there was no principal name set) https://fedorahosted.org/freeipa/ticket/3481
* Configure ipa_dns DS plugin on install and upgradeMartin Kosek2013-03-221-0/+6
| | | | | | | | | | The plugin is configured unconditionally (i.e. does not check if IPA was configured with DNS) as the plugin is needed on all replicas to prevent objectclass violations due to missing SOA serial in idnsZone objectclass. The violation could happen if just one replica configured DNS and added a new zone. https://fedorahosted.org/freeipa/ticket/3347
* Enforce exact SID match when adding or modifying a ID rangeTomas Babej2013-03-141-13/+37
| | | | | | | | SID validation in idrange.py now enforces exact match on SIDs, thus one can no longer use SID of an object in a trusted domain as a trusted domain SID. https://fedorahosted.org/freeipa/ticket/3432
* Fix installing server with external CAPetr Viktorin2013-03-082-31/+32
| | | | | | | | | | | | | | Reorganize ipa-server-instal so that DS (and NTP server) installation only happens in step one. Change CAInstance to behave correctly in two-step install. Add an `init_info` method to DSInstance that includes common attribute/sub_dict initialization from create_instance and create_replica. Use it in ipa-server-install to get a properly configured DSInstance for later tasks. https://fedorahosted.org/freeipa/ticket/3459
* Don't base64-encode the CA cert when uploading it during an upgrade.Rob Crittenden2013-03-071-2/+1
| | | | | | | | We want to store the raw value. Tools like ldapsearch will automatically base64 encode the value because it's binary so we don't want to duplicate that. https://fedorahosted.org/freeipa/ticket/3477
* Add client capabilities, enable messagesPetr Viktorin2013-02-211-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The API version the client sends can now be used to check what the client expects or is capable of. All version tests IPA does will be be named and listed in one module, ipalib.capabilities, which includes a function to test a specific capability against an API version. Similarly to Python's __future__ module, capabilities.py also serves as documentation of backwards-incompatible changes to the API. The first capability to be defined is "messages". Recent enough clients can accept a list of warnings or other info under the "messages" key in the result dict. If a JSON client does not send the API version, it is assumed this is a testing client (e.g. curl from the command line). Such a client "has" all capabilities, but it will always receive a warning mentioning that forward compatibility is not guaranteed. If a XML client does not send the API version, it is assumed it uses the API version before capabilities were introduced. (This is to keep backwards compatibility with clients containing bug https://fedorahosted.org/freeipa/ticket/3294) Whenever a capability is added, the API version must be incremented. To ensure that, capabilities are written to API.txt and checked by `makeapi --validate`. Design page: http://freeipa.org/page/V3/Messages Ticket: https://fedorahosted.org/freeipa/ticket/2732
* Avoid internal error when user is not Trust adminMartin Kosek2013-02-201-4/+23
| | | | | | | | | | | | | | | When user tries to perform any action requiring communication with trusted domain, IPA server tries to retrieve a trust secret on his behalf to be able to establish the connection. This happens for example during group-add-member command when external user is being resolved in the AD. When user is not member of Trust admins group, the retrieval crashes and reports internal error. Catch this exception and rather report properly formatted ACIError. Also make sure that this exception is properly processed in group-add-member post callback. https://fedorahosted.org/freeipa/ticket/3390
* Implement the cert-find command for the dogtag CA backend.Rob Crittenden2013-02-192-0/+146
| | | | | | | | | | | | | | | | Use a new RESTful API provided by dogtag 10+. Construct an XML document representing the search request. The output is limited to whatever dogtag sends us, there is no way to request additional attributes other than to read each certificate individually. dogtag uses a boolean for each search term to indicate that it is used. Presense of the search item is not enough, both need to be set. The search operation is unauthenticated Design page: http://freeipa.org/page/V3/Cert_find https://fedorahosted.org/freeipa/ticket/2528
* Allow ipa-replica-conncheck and ipa-adtrust-install to read krb5 includedirJakub Hrozek2013-02-181-1/+1

* Add option to specify SID using domain name to idrange-add/modTomas Babej2013-02-181-0/+10
| | | | | | | | | | When adding/modifying an ID range for a trusted domain, the newly added option --dom-name can be used. This looks up SID of the trusted domain in LDAP and therefore the user is not required to write it down in CLI. If the lookup fails, error message asking the user to specify the SID manually is shown. https://fedorahosted.org/freeipa/ticket/3133
* Add support for AD users to hbactest commandMartin Kosek2013-02-141-0/+56
| | | | | | | | | | | | | | | | | | | | | How this works: 1. When a trusted domain user is tested, AD GC is searched for the user entry Distinguished Name 2. The user entry is then read from AD GC and its SID and SIDs of all its assigned groups (tokenGroups attribute) are retrieved 3. The SIDs are then used to search IPA LDAP database to find all external groups which have any of these SIDs as external members 4. All these groups having these groups as direct or indirect members are added to hbactest allowing it to perform the search LIMITATIONS: - only Trusted Admins group members can use this function as it uses secret for IPA-Trusted domain link - List of group SIDs does not contain group memberships outside of the trusted domain https://fedorahosted.org/freeipa/ticket/2997
* Generalize AD GC searchMartin Kosek2013-02-141-50/+95
| | | | | | | | | | | | | | Modify access methods to AD GC so that callers can specify a custom basedn, filter, scope and attribute list, thus allowing it to perform any LDAP search. Error checking methodology in these functions was changed, so that it rather raises an exception with a desription instead of simply returning a None or False value which would made an investigation why something does not work much more difficult. External membership method in group-add-member command was updated to match this approach. https://fedorahosted.org/freeipa/ticket/2997
* Test NetBIOS name clash before creating a trustMartin Kosek2013-02-131-0/+6
| | | | | | | Give a clear message about what is wrong with current Trust settings before letting AD to return a confusing error message. https://fedorahosted.org/freeipa/ticket/3193
* Add SID blacklist attributesMartin Kosek2013-02-121-0/+8
| | | | | | | | Update our LDAP schema and add 2 new attributes for SID blacklist definition. These new attributes can now be set per-trust with trustconfig command. https://fedorahosted.org/freeipa/ticket/3289
* Port ipa-replica-prepare to the admintool frameworkPetr Viktorin2013-02-041-0/+504
| | | | | | | | | | | | | Break the script into several smaller methods. Use modern idioms: os.path.join instead of string addition; the with statement for closing files. Add --quiet, --verbose, and --log-file options. Use logging instead of print statements. (http://freeipa.org/page/V3/Logging_and_output) Part of: https://fedorahosted.org/freeipa/ticket/2652 Fixes: https://fedorahosted.org/freeipa/ticket/3285
* Better logging for AdminTool and ipa-ldap-updaterRob Crittenden2013-02-041-26/+22
| | | | | | | | | | | | | - Automatically add a "Logging and output options" group with the --quiet, --verbose, --log-file options. - Set up logging based on these options; details are in the setup_logging docstring and in the design document. - Don't bind log methods as individual methods of the class. This means one less linter exception. - Make the help for command line options consistent with optparse's --help and --version options. Design document: http://freeipa.org/page/V3/Logging_and_output
* Use fully qualified CCACHE namesMartin Kosek2013-02-011-3/+12
| | | | | | | | | | | | | | Some parts of install scripts used only ccache name as returned by krbV.CCache.name attribute. However, when this name is used again to initialize krbV.CCache object or when it is used in KRB5CCNAME environmental variable, it fails for new DIR type of CCACHE. We should always use both CCACHE type and name when referring to them to avoid these crashes. ldap2 backend was also updated to accept directly krbV.CCache object which contains everything we need to authenticate with ccache. https://fedorahosted.org/freeipa/ticket/3381
* Remove unused krbV importsMartin Kosek2013-02-011-2/+0

* Fix migration for openldap DSMartin Kosek2013-02-011-2/+9
| | | | | | | | | | | | | | | | | openldap server does not store its schema in cn=schema entry, but rather in cn=subschema. Add a fallback to ldap2 plugin to read from this entry when cn=schema is not found. ldap2 plugin uses the schema when doing some of the automatic encoding, like an automatic encoding of DN object. IPA migration plugin DN attribute processing is now also more tolerant when it finds that some DN attribute was not autoencoded. It tries to convert it to DN on its own and report a warning and continue with user processing when the conversion fails instead of crashing with AssertionError and thus abandoning the whole migration run. https://fedorahosted.org/freeipa/ticket/3372
* Use new certmonger locking to prevent NSS database corruption.Rob Crittenden2013-01-291-13/+100
| | | | | | | | | | | | | | | | | | | | | | | | dogtag opens its NSS database in read/write mode so we need to be very careful during renewal that we don't also open it up read/write. We basically need to serialize access to the database. certmonger does the majority of this work via internal locking from the point where it generates a new key/submits a rewewal through the pre_save and releases the lock after the post_save command. This lock is held per NSS database so we're save from certmonger. dogtag needs to be shutdown in the pre_save state so certmonger can safely add the certificate and we can manipulate trust in the post_save command. Fix a number of bugs in renewal. The CA wasn't actually being restarted at all due to a naming change upstream. In python we need to reference services using python-ish names but the service is pki-cad. We need a translation for non-Fedora systems as well. Update the CA ou=People entry when he CA subsystem certificate is renewed. This certificate is used as an identity certificate to bind to the DS instance. https://fedorahosted.org/freeipa/ticket/3292 https://fedorahosted.org/freeipa/ticket/3322
* Add the CA cert to LDAP after the CA installPetr Viktorin2013-01-291-2/+1
| | | | | | | | | | | | | The DS is installed before the CA cert is generated. Trying to add the cert to LDAP before it exists resulted in a nasty-looking error message. This moves the cert upload to after the CA cert is ready and the certdb is created. Move the cert upload to after thecertdb is generated. https://fedorahosted.org/freeipa/ticket/3375
* Pylint cleanup.Jan Cholasta2013-01-291-2/+2
| | | | | | | Add more dynamic attribute info to IPATypeChecker in make-lint. Remove unnecessary pylint comments. Fix false positivies introduced by Pylint 0.26. https://fedorahosted.org/freeipa/ticket/3379
* Update anonymous access ACI to protect secret attributes.Rob Crittenden2013-01-232-0/+82
| | | | | | | Update anonymous access ACI so that no users besides Trust Admins users can read AD Trust key attributes (ipaNTTrustAuthOutgoing, ipaNTTrustAuthIncoming). The change is applied both for updated IPA servers and new installations.
* Use secure method to acquire IPA CA certificateJohn Dennis2013-01-231-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Major changes ipa-client-install: * Use GSSAPI connection to LDAP server to download CA cert (now the default method) * Add --ca-cert-file option to load the CA cert from a disk file. Validate the file. If this option is used the supplied CA cert is considered definitive. * The insecure HTTP retrieval method is still supported but it must be explicitly forced and a warning will be emitted. * Remain backward compatible with unattended case (except for aberrant condition when preexisting /etc/ipa/ca.crt differs from securely obtained CA cert, see below) * If /etc/ipa/ca.crt CA cert preexists the validate it matches the securely acquired CA cert, if not: - If --unattended and not --force abort with error - If interactive query user to accept new CA cert, if not abort In either case warn user. * If interactive and LDAP retrieval fails prompt user if they want to proceed with insecure HTTP method * If not interactive and LDAP retrieval fails abort unless --force * Backup preexisting /etc/ipa/ca.crt in FileStore prior to execution, if ipa-client-install fails it will be restored. Other changes: * Add new exception class CertificateInvalidError * Add utility convert_ldap_error() to ipalib.ipautil * Replace all hardcoded instances of /etc/ipa/ca.crt in ipa-client-install with CACERT constant (matches existing practice elsewhere). * ipadiscovery no longer retrieves CA cert via HTTP. * Handle LDAP minssf failures during discovery, treat failure to check ldap server as a warninbg in absebce of a provided CA certificate via --ca-cert-file or though existing /etc/ipa/ca.crt file.

* Update plugin to upload CA certificate to LDAPAlexander Bokovoy2013-01-231-0/+56
| | | | | | Define post-update plugin to upload public CA certificate to IPA LDAP server. The plugin includes also update file that creates default container for the certificate.
* Upload CA cert in the directory on installSimo Sorce2013-01-231-0/+15
| | | | | This will later allow clients to securely download the CA cert by performaing mutual auth using LDAP with GSSAPI
* Installer should not connect to 127.0.0.1Martin Kosek2013-01-212-3/+3
| | | | | | | | | | | | | IPA installer sometimes tries to connect to the Directory Server via loopback address 127.0.0.1. However, the Directory Server on pure IPv6 systems may not be listening on this address. This address may not even be available. Rather use the FQDN of the server when connecting to the DS to fix this issue and make the connection consistent ldapmodify calls which also use FQDN instead of IP address. https://fedorahosted.org/freeipa/ticket/3355
* Sort LDAP updates properlyMartin Kosek2013-01-111-19/+16
| | | | | | | | | | | | LDAP updates were sorted by number of RDNs in DN. This, however, sometimes caused updates to be executed before cn=schema updates. If the update required an objectClass or attributeType added during the cn=schema update, the update operation failed. Fix the sorting so that the cn=schema updates are always run first and then the other updates sorted by RDN count. https://fedorahosted.org/freeipa/ticket/3342

* Compliant client side session cookie behaviorJohn Dennis2012-12-101-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In summary this patch does: * Follow the defined rules for cookies when: - receiving a cookie (process the attributes) - storing a cookie (store cookie + attributes) - sending a cookie + validate the cookie domain against the request URL + validate the cookie path against the request URL + validate the cookie expiration + if valid then send only the cookie, no attribtues * Modifies how a request URL is stored during a XMLRPC request/response sequence. * Refactors a bit of the request/response logic to allow for making the decision whether to send a session cookie instead of full Kerberous auth easier. * The server now includes expiration information in the session cookie it sends to the client. The server always had the information available to prevent using an expired session cookie. Now that expiration timestamp is returned to the client as well and now the client will not send an expired session cookie back to the server. * Adds a new module and unit test for cookies (see below) Formerly we were always returning the session cookie no matter what the domain or path was in the URL. We were also sending the cookie attributes which are for the client only (used to determine if to return a cookie). The attributes are not meant to be sent to the server and the previous behavior was a protocol violation. We also were not checking the cookie expiration. Cookie library issues: We need a library to create, parse, manipulate and format cookies both in a client context and a server context. Core Python has two cookie libraries, Cookie.py and cookielib.py. Why did we add a new cookie module instead of using either of these two core Python libaries? Cookie.py is designed for server side generation but can be used to parse cookies on the client. It's the library we were using in the server. However when I tried to use it in the client I discovered it has some serious bugs. There are 7 defined cookie elements, it fails to correctly parse 3 of the 7 elements which makes it unusable because we depend on those elements. Since Cookie.py was designed for server side cookie processing it's not hard to understand how fails to correctly parse a cookie because that's a client side need. (Cookie.py also has an awkward baroque API and is missing some useful functionality we would have to build on top of it). cookielib.py is designed for client side. It's fully featured and obeys all the RFC's. It would be great to use however it's tightly coupled with another core library, urllib2.py. The http request and response objects must be urllib2 objects. But we don't use urllib2, rather we use httplib because xmlrpclib uses httplib. I don't see a reason why a cookie library should be so tightly coupled to a protocol library, but it is and that means we can't use it (I tried to just pick some isolated entrypoints for our use but I kept hitting interaction/dependency problems). I decided to solve the cookie library problems by writing a minimal cookie library that does what we need and no more than that. It is a new module in ipapython shared by both client and server and comes with a new unit test. The module has plenty of documentation, no need to repeat it here. Request URL issues: We also had problems in rpc.py whereby information from the request which is needed when we process the response is not available. Most important was the requesting URL. It turns out that the way the class and object relationships are structured it's impossible to get this information. Someone else must have run into the same issue because there was a routine called reconstruct_url() which attempted to recreate the request URL from other available information. Unfortunately reconstruct_url() was not callable from inside the response handler. So I decided to store the information in the thread context and when the request is received extract it from the thread context. It's perhaps not an ideal solution but we do similar things elsewhere so at least it's consistent. I removed the reconstruct_url() function because the exact information is now in the context and trying to apply heuristics to recreate the url is probably not robust.

* Use DN objects for Dogtag configurationPetr Viktorin2012-12-101-6/+12
| | | | | Use our DN objects for generating DNs, instead of relying on string operations.
* Configuring CA with ConfigParser.Endi Sukma Dewata2012-12-101-78/+82
| | | | | | | | | The configuration code has been modified to use the ConfigParser to set the parameters in the CA section in the deployment configuration. This allows IPA to define additional PKI subsystems in the same configuration file. PKI Ticket #399 (https://fedorahosted.org/pki/ticket/399)
* Add OCSP and CRL URIs to certificatesMartin Kosek2012-12-072-26/+186
| | | | | | | | | | | | | | | | | Modify the default IPA CA certificate profile to include CRL and OCSP extensions which will add URIs to IPA CRL&OCSP to published certificates. Both CRL and OCSP extensions have 2 URIs, one pointing directly to the IPA CA which published the certificate and one to a new CNAME ipa-ca.$DOMAIN which was introduced as a general CNAME pointing to all IPA replicas which have CA configured. The new CNAME is added either during new IPA server/replica/CA installation or during upgrade. https://fedorahosted.org/freeipa/ticket/3074 https://fedorahosted.org/freeipa/ticket/1431
* Add detection for users from trusted/invalid realmsTomas Babej2012-12-063-18/+40
| | | | | | | | | | | | When user from other realm than FreeIPA's tries to use Web UI (login via forms-based auth or with valid trusted realm ticket), the 401 Unauthorized error with X-Ipa-Rejection-Reason=denied is returned. Also, the support for usernames of the form user@SERVER.REALM or user@server.realm was added. https://fedorahosted.org/freeipa/ticket/3252
* Propagate kinit errors with trust accountAlexander Bokovoy2012-11-271-0/+4
| | | | | | | | | | When using Global Catalog for resolving users and groups, one needs to authenticate against Active Directory DC using GSSAPI. Obtaining Kerberos ticket might fail. Make sure the failure message is actually returned to the user so that decision can be made about the source of issue. https://fedorahosted.org/freeipa/ticket/3265
* Make ipa-csreplica-manage work with both merged and non-merged DBsPetr Viktorin2012-11-231-13/+11
| | | | | | | | | | | | The ipa-csreplica-manage tool often assumed that the port numbers are the same on both sides of a replication agreement. This assumption doesn't hold in a cluster with both old-style hosts and ones with merged DBs. When managing agreements, determine the port with the PKI (or merged) DS on each master, and use it. Also, in CSReplicationManager, always use starttls rather than ldaps://.
* Provide 'protocol' argument to IPAdminPetr Viktorin2012-11-231-11/+27
| | | | | | | | | | | The ancient IPAdmin class used some heuristics to determine the protocol to connect with (ldap, ldaps, or ldapi). In turn, some calling code used questionable mechanisms to get the correct protocol: in ipaserver/install/replication.py, the CA cert was either passed to the constructor or added to the class afterwards, to get ldap:// or ldaps://. Add an explicit protocol argument and only fall back to backwards-compatible guessing if it is not given.
* Filter suffix in replication management toolsMartin Kosek2012-11-231-7/+30
| | | | | | | | | With the new unified Dogtag10 LDAP database, PKI-CA data and the agreements themselves are now in the main LDAP instance. Replication management tools now need to properly filter replication agreements based on the suffix to avoid clashing of agreements of different types.
* Properly stop tracking certificates on uninstallPetr Viktorin2012-11-231-15/+23
| | | | | | | | | | Stopping certificate tracking was done as part of the PKI DS uninstall. Since with the merged DB, thePKI DS is not used any more, this step was skipped. Move certificate untracking to a separate step and call it separately. Also, the post-uninstall check for tracked certificates used the wrong set of Dogtag constants. Fix the issue.
* Update certmap.conf on IPA upgradesPetr Viktorin2012-11-231-1/+1
| | | | | | | | This brings /etc/dirsrv/slapd-REALM/certmap.conf under IPA control. The file is overwritten on upgrades. This ensures that the cert for the ipaca user is recognized when ipa-ca-install is run on older masters.
* Use correct Dogtag configuration in get_pin and get_ca_certchainPetr Viktorin2012-11-231-12/+12
| | | | | | Some install utilities used Dogtag configuration before Dogtag was configured. Fix by passing the relevant dogtag_constants where they're needed.
* Fix schema replication from old mastersPetr Viktorin2012-11-231-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new merged database will replicate with both the IPA and CA trees, so all DS instances (IPA and CA on the existing master, and the merged one on the replica) need to have the same schema. Dogtag does all its schema modifications online. Those are replicated normally. The basic IPA schema, however, is delivered in ldif files, which are not replicated. The files are not present on old CA DS instances. Any schema update that references objects in these files will fail. The whole 99user.ldif (i.e. changes introduced dynamically over LDAP) is replicated as a blob. If we updated the old master's CA schema dynamically during replica install, it would conflict with updates done during the installation: the one with the lower CSN would get lost. Dogtag's spawn script recently grew a new flag, 'pki_clone_replicate_schema'. Turning it off tells Dogtag to create its schema in the clone, where the IPA modifications are taking place, so that it is not overwritten by the IPA schema on replication. The patch solves the problems by: - In __spawn_instance, turning off the pki_clone_replicate_schema flag. - Providing a script to copy the IPA schema files to the CA DS instance. The script needs to be copied to old masters and run there. - At replica CA install, checking if the schema is updated, and failing if not. The --skip-schema-check option is added to ipa-{replica,ca}-install to override the check. All pre-3.1 CA servers in a domain will have to have the script run on them to avoid schema replication errors. https://fedorahosted.org/freeipa/ticket/3213
* Changes to use a single database for dogtag and IPAAde Lee2012-11-234-31/+115
| | | | | | | | | | | | New servers that are installed with dogtag 10 instances will use a single database instance for dogtag and IPA, albeit with different suffixes. Dogtag will communicate with the instance through a database user with permissions to modify the dogtag suffix only. This user will authenticate using client auth using the subsystem cert for the instance. This patch includes changes to allow the creation of masters and clones with single ds instances.
