* Use secure method to acquire IPA CA certificateJohn Dennis2013-01-231-30/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Do not crash when Kerberos SRV record is not foundMartin Kosek2013-01-021-2/+3
| | | | | | | | ipa-client-install crashed when IPA server realm TXT record was configured, but the referred domain (lower-case realm value) did not contain any Kerberos SRV record (_kerberos._udp.<realm>.) https://fedorahosted.org/freeipa/ticket/3316
* Stop and disable conflicting time&date servicesMartin Kosek2012-12-071-0/+68
| | | | | | | | | | | | | | | | | | | | Fedora 16 introduced chrony as default client time&date synchronization service: http://fedoraproject.org/wiki/Features/ChronyDefaultNTP Thus, there may be people already using chrony as their time and date synchronization service before installing IPA. However, installing IPA server or client on such machine may lead to unexpected behavior, as the IPA installer would configure ntpd and leave the machine with both ntpd and chronyd enabled. However, since the OS does not allow both chronyd and ntpd to be running concurrently and chronyd has the precedence, ntpd would not be run on that system at all. Make sure, that user is warned when trying to install IPA on such system and is given a possibility to either not to let IPA configure ntpd at all or to let the installer stop and disable chronyd. https://fedorahosted.org/freeipa/ticket/2974

* Notify user about necessary ports in ipa-client-installTomas Babej2012-10-091-0/+1
| | | | | | | | | | | | Connection error message in ipa-client-install now warns the user about the need of opening of all the necessary ports for ipa-client enrollment when error that might have been caused by closed ports is encountered. Mentions the ports needed after the client enrollment as well. Improves other error messages during installation in various ways. https://fedorahosted.org/freeipa/ticket/2816
* Improve DN usage in ipa-client-installMartin Kosek2012-10-022-63/+118
| | | | | | | | | | | | | | | | | | | | | A hotfix pushed in a scope of ticket 3088 forced conversion of DN object (baseDN) in IPA client discovery so that ipa-client-install does not crash when creating an IPA default.conf. Since this is not a preferred way to handle DN objects, improve its usage: - make sure, that baseDN retrieved by client discovery is always a DN object - update ipachangeconf.py code to handle strings better and instead of concatenating objects, make sure they are converted to string first As a side-effect of ipachangeconf changes, default.conf config file generated by ipa-client-install has no longer empty new line at the end of a file. Whole ipachangeconf.py has been modified to be compliant with PEP8. https://fedorahosted.org/freeipa/ticket/3088
* Properly convert DN in ipa-client-installMartin Kosek2012-09-181-1/+1
| | | | | | | | | | | ipa-client-install crashed when IPA server anonymous access was disabled and base DN was thus generated via realm_to_suffix function which, however, returns a DN object and not string. DN was converted to string, ipa-client-install no longer crashes in this scenario. https://fedorahosted.org/freeipa/ticket/3088
* Run ntpdate in verbose mode, not debug (i.e. no-op) modePetr Viktorin2012-09-041-6/+4
| | | | | | | Remove the debug argument to synconce_ntp since we always want the logs to be verbose. https://fedorahosted.org/freeipa/ticket/3048
* Use DN objects instead of stringsJohn Dennis2012-08-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Convert every string specifying a DN into a DN object * Every place a dn was manipulated in some fashion it was replaced by the use of DN operators * Add new DNParam parameter type for parameters which are DN's * DN objects are used 100% of the time throughout the entire data pipeline whenever something is logically a dn. * Many classes now enforce DN usage for their attributes which are dn's. This is implmented via ipautil.dn_attribute_property(). The only permitted types for a class attribute specified to be a DN are either None or a DN object. * Require that every place a dn is used it must be a DN object. This translates into lot of:: assert isinstance(dn, DN) sprinkled through out the code. Maintaining these asserts is valuable to preserve DN type enforcement. The asserts can be disabled in production. The goal of 100% DN usage 100% of the time has been realized, these asserts are meant to preserve that. The asserts also proved valuable in detecting functions which did not obey their function signatures, such as the baseldap pre and post callbacks. * Moved ipalib.dn to ipapython.dn because DN class is shared with all components, not just the server which uses ipalib. * All API's now accept DN's natively, no need to convert to str (or unicode). * Removed ipalib.encoder and encode/decode decorators. Type conversion is now explicitly performed in each IPASimpleLDAPObject method which emulates a ldap.SimpleLDAPObject method. * Entity & Entry classes now utilize DN's * Removed __getattr__ in Entity & Entity clases. There were two problems with it. It presented synthetic Python object attributes based on the current LDAP data it contained. There is no way to validate synthetic attributes using code checkers, you can't search the code to find LDAP attribute accesses (because synthetic attriutes look like Python attributes instead of LDAP data) and error handling is circumscribed. Secondly __getattr__ was hiding Python internal methods which broke class semantics. * Replace use of methods inherited from ldap.SimpleLDAPObject via IPAdmin class with IPAdmin methods. Directly using inherited methods was causing us to bypass IPA logic. Mostly this meant replacing the use of search_s() with getEntry() or getList(). Similarly direct access of the LDAP data in classes using IPAdmin were replaced with calls to getValue() or getValues(). * Objects returned by ldap2.find_entries() are now compatible with either the python-ldap access methodology or the Entity/Entry access methodology. * All ldap operations now funnel through the common IPASimpleLDAPObject giving us a single location where we interface to python-ldap and perform conversions. * The above 4 modifications means we've greatly reduced the proliferation of multiple inconsistent ways to perform LDAP operations. We are well on the way to having a single API in IPA for doing LDAP (a long range goal). * All certificate subject bases are now DN's * DN objects were enhanced thusly: - find, rfind, index, rindex, replace and insert methods were added - AVA, RDN and DN classes were refactored in immutable and mutable variants, the mutable variants are EditableAVA, EditableRDN and EditableDN. By default we use the immutable variants preserving important semantics. To edit a DN cast it to an EditableDN and cast it back to DN when done editing. These issues are fully described in other documentation. - first_key_match was removed - DN equalty comparison permits comparison to a basestring * Fixed ldapupdate to work with DN's. This work included: - Enhance test_updates.py to do more checking after applying update. Add test for update_from_dict(). Convert code to use unittest classes. - Consolidated duplicate code. - Moved code which should have been in the class into the class. - Fix the handling of the 'deleteentry' update action. It's no longer necessary to supply fake attributes to make it work. Detect case where subsequent update applies a change to entry previously marked for deletetion. General clean-up and simplification of the 'deleteentry' logic. - Rewrote a couple of functions to be clearer and more Pythonic. - Added documentation on the data structure being used. - Simplfy the use of update_from_dict() * Removed all usage of get_schema() which was being called prior to accessing the .schema attribute of an object. If a class is using internal lazy loading as an optimization it's not right to require users of the interface to be aware of internal optimization's. schema is now a property and when the schema property is accessed it calls a private internal method to perform the lazy loading. * Added SchemaCache class to cache the schema's from individual servers. This was done because of the observation we talk to different LDAP servers, each of which may have it's own schema. Previously we globally cached the schema from the first server we connected to and returned that schema in all contexts. The cache includes controls to invalidate it thus forcing a schema refresh. * Schema caching is now senstive to the run time context. During install and upgrade the schema can change leading to errors due to out-of-date cached schema. The schema cache is refreshed in these contexts. * We are aware of the LDAP syntax of all LDAP attributes. Every attribute returned from an LDAP operation is passed through a central table look-up based on it's LDAP syntax. The table key is the LDAP syntax it's value is a Python callable that returns a Python object matching the LDAP syntax. There are a handful of LDAP attributes whose syntax is historically incorrect (e.g. DistguishedNames that are defined as DirectoryStrings). The table driven conversion mechanism is augmented with a table of hard coded exceptions. Currently only the following conversions occur via the table: - dn's are converted to DN objects - binary objects are converted to Python str objects (IPA convention). - everything else is converted to unicode using UTF-8 decoding (IPA convention). However, now that the table driven conversion mechanism is in place it would be trivial to do things such as converting attributes which have LDAP integer syntax into a Python integer, etc. * Expected values in the unit tests which are a DN no longer need to use lambda expressions to promote the returned value to a DN for equality comparison. The return value is automatically promoted to a DN. The lambda expressions have been removed making the code much simpler and easier to read. * Add class level logging to a number of classes which did not support logging, less need for use of root_logger. * Remove ipaserver/conn.py, it was unused. * Consolidated duplicate code wherever it was found. * Fixed many places that used string concatenation to form a new string rather than string formatting operators. This is necessary because string formatting converts it's arguments to a string prior to building the result string. You can't concatenate a string and a non-string. * Simplify logic in rename_managed plugin. Use DN operators to edit dn's. * The live version of ipa-ldap-updater did not generate a log file. The offline version did, now both do. https://fedorahosted.org/freeipa/ticket/1670 https://fedorahosted.org/freeipa/ticket/1671 https://fedorahosted.org/freeipa/ticket/1672 https://fedorahosted.org/freeipa/ticket/1673 https://fedorahosted.org/freeipa/ticket/1674 https://fedorahosted.org/freeipa/ticket/1392 https://fedorahosted.org/freeipa/ticket/2872
* Make client server option multi-valued, allow disabling DNS discoveryRob Crittenden2012-07-101-0/+3
| | | | | | | | | | | | | Let the --server option be specified multiple times on the command line. The first one passed in is the one we enroll against. Do additional verification before setting dnsok so we can be sure that the record(s) were actually discovered in DNS. If servers are provided on the CLI and --fixed-primary is set then _srv_ is not added to ipa_server in sssd.conf. https://fedorahosted.org/freeipa/ticket/2841
* Improve autodiscovery loggingPetr Viktorin2012-06-171-42/+93
| | | | | | | | | | | | | | | | | | | | Track the source of discovered values (e.g. from option, interactive, retrieved from DNS), and show it in the log in the configuration overview and on erorrs involving the value. Add additional log messages explaining the autodiscovery process. For domains the discovery tries to get LDAP SRV records from, log reasons explaining why the domain was chosen. Also, prevent the same domain from being searched multiple times. Add names for error codes, and show them in the log. Also, modernize the discovery code a bit: move away from the Java-style accessors, don't needlessly pre-declare variables, make IPADiscovery a new-style class. https://fedorahosted.org/freeipa/ticket/2553
* Replace DNS client based on acutil with python-dnsMartin Kosek2012-05-242-79/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | IPA client and server tool set used authconfig acutil module to for client DNS operations. This is not optimal DNS interface for several reasons: - does not provide native Python object oriented interface but but rather C-like interface based on functions and structures which is not easy to use and extend - acutil is not meant to be used by third parties besides authconfig and thus can break without notice Replace the acutil with python-dns package which has a feature rich interface for dealing with all different aspects of DNS including DNSSEC. The main target of this patch is to replace all uses of acutil DNS library with a use python-dns. In most cases, even though the larger parts of the code are changed, the actual functionality is changed only in the following cases: - redundant DNS checks were removed from verify_fqdn function in installutils to make the whole DNS check simpler and less error-prone. Logging was improves for the remaining checks - improved logging for ipa-client-install DNS discovery https://fedorahosted.org/freeipa/ticket/2730 https://fedorahosted.org/freeipa/ticket/1837
* Check through all LDAP servers in the domain during IPA discoveryAlexander Bokovoy2011-12-091-9/+25
| | | | | | | | | When discovering IPA LDAP servers through DNS records, look through all servers found until first success. A master might be not available or denied access but replica may succeed. Ticket #1827 https://fedorahosted.org/freeipa/ticket/1827
* ticket 2022 - modify codebase to utilize IPALogManager, obsoletes loggingJohn Dennis2011-11-231-16/+16
| | | | | | | | | | | | change default_logger_level to debug in configure_standard_logging add new ipa_log_manager module, move log_mgr there, also export root_logger from log_mgr. change all log_manager imports to ipa_log_manager and change log_manager.root_logger to root_logger. add missing import for parse_log_level()
* ipa-client-install hangs if the discovered server is unresponsiveMartin Kosek2011-10-121-1/+2
| | | | | | | | Add a timeout to the wget call to cover a case when autodiscovered server does not response to our attempt to download ca.crt. Let user specify a different IPA server in that case. https://fedorahosted.org/freeipa/ticket/1960
* Before kinit, try to sync time with the NTP servers of the domain we are joiningAlexander Bokovoy2011-10-062-0/+43
| | | | | | | | | | | | | | When running ipa-client-install on a system whose clock is not in sync with the master, kinit fails and enrollment is aborted. Manual checking of current time at the master and adjusting on the client-to-be is then needed. The patch tries to fetch SRV records for NTP servers of the domain we aim to join and runs ntpdate to get time synchronized. If no SRV records are found, sync with IPA server itself. If that fails, warn that time might be not in sync with KDC. https://fedorahosted.org/freeipa/ticket/1773
* Setup and restore ntp configuration on the client side properlyAlexander Bokovoy2011-10-051-15/+37
| | | | | | | | | When setting up the client-side NTP configuration, make sure that /etc/ntp/step-tickers point to IPA NTP server as well. When restoring the client during ipa-client-install --uninstall, make sure NTP configuration is fully restored and NTP service is disabled if it was disabled before the installation. https://fedorahosted.org/freeipa/ticket/1770

* ipa-client assumes a single namingcontextMartin Kosek2011-09-301-18/+14
| | | | | | | | | When LDAP server contains more that one suffixes, the ipa client installation does not detect it as IPA server and fails to install. Fix ipa server discovery so that it correctly searches all naming contexts for the IPA one. https://fedorahosted.org/freeipa/ticket/1868

* KDC autodiscovery may fail when domain is not realmMartin Kosek2011-05-171-10/+16
| | | | | | | | | | | | | When ipa-client-install autodiscovers IPA server values it doesn't fill the fixed KDC address to Kerberos configuration file. However, when realm != domain or the autodiscovered values are overridden, installation may fail because it cannot find the KDC. This patch adds a failover to use static KDC address in case when such an issue occurs. https://fedorahosted.org/freeipa/ticket/1100

* Change FreeIPA license to GPLv3+Jakub Hrozek2010-12-204-24/+24
| | | | | | | | | | The changes include: * Change license blobs in source files to mention GPLv3+ not GPLv2 only * Add GPLv3+ license text * Package COPYING not LICENSE as the license blobs (even the old ones) mention COPYING specifically, it is also more common, I think https://fedorahosted.org/freeipa/ticket/239
* Better distinguish between when DNS discovery works and search more domains.Rob Crittenden2010-09-201-9/+61
| | | | | | | | | | | | | | | | | | | | | | Passing domain and server on the command-line used to be considered as DNS autodiscovery worked. This was problematic if there was in fact no SRV records because krb5.conf would be configured without a specific KDC causing all Kerberos ops to fail. Now if you pass in a domain/server it still tries to see if they are discoverable and if so won't hardcode a server, but will fall back to doing so if necessary. Also be a lot more aggressive on looking for the SRV records. Use the search and domain values from /etc/resolv.conf on the chance that the SRV records aren't in the domain of the hostname of the machine. An example of this would be if your laptop is in dhcp.example.com and your company's SRV records are in corp.example.com. Searching dhcp.example.com and example.com won't find the SRV records but the user is likely to have corp.redhat.com in the search list, at least. ticket 234
