* IPA: Look up AD users directly if IPA server mode is onJakub Hrozek2013-06-286-6/+168
| | | | | | | | https://fedorahosted.org/sssd/ticket/1962 If the ipa_server_mode is selected IPA subdomain user and group lookups are not done with the help of the extdom plugin but directly against AD using the AD ID code.
* IPA: Create and remove AD id_ctx for subdomains discovered in server modeJakub Hrozek2013-06-281-0/+182
| | | | | | | | | When IPA server mode is on, then this patch will create an ad_id_ctx for each subdomain discovered in IPA provider. The ID context is needed to perform direct lookups using the AD provider. Subtask of: https://fedorahosted.org/sssd/ticket/1962
* AD: Move storing sdap_domain for subdomain to generic LDAP codeJakub Hrozek2013-06-283-65/+78
| | | | | | | | Makes creating the sdap_domain structure for a subdomain reusable outside AD subdomain code where it was created initially. Subtask of: https://fedorahosted.org/sssd/ticket/1962
* IPA: Initialize server mode ctx if server mode is onJakub Hrozek2013-06-284-0/+62
| | | | | | | | | | This patch introduces a new structure that holds information about a subdomain and its ad_id_ctx. This structure will be used only in server mode to make it possible to search subdomains with a particular ad_id_ctx. Subtask of: https://fedorahosted.org/sssd/ticket/1962
* AD: initialize failover with custom realm, domain and failover serviceJakub Hrozek2013-06-283-28/+41
| | | | | | | | | | This is needed so we can initialize failover using IPA realm and on-the-fly discovered DNS domain. The subdomains discovered on-thefly will use the subdomain name for realm, domain and failover service to avoid conflicts. Subtaks of: https://fedorahosted.org/sssd/ticket/1962
* AD: decouple ad_id_ctx initializationJakub Hrozek2013-06-283-102/+285
| | | | | | | | | The IPA subdomain code will perform lookups on its own in the server mode. For this, the AD provider must offer a way to initialize the ad_id_ctx for external consumers. Subtask of: https://fedorahosted.org/sssd/ticket/1962
* LDAP: Add utility function sdap_copy_mapJakub Hrozek2013-06-282-0/+45
| | | | | | | | | The AD subdomains will only use default options values. This patch introduces a new utility function sdap_copy_map() that copies the default options map. Subtask of: https://fedorahosted.org/sssd/ticket/1962
* IPA: Add a server mode optionJakub Hrozek2013-06-282-0/+2
| | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1993 SSSD needs to know that it is running on an IPA server and should not look up trusted users and groups with the help of the extdom plugin but do the lookups on its own. For this a new boolean configuration option, is introduced which defaults to false but is set to true during ipa-server-install or during updates of the FreeIPA server if it is not already set.
* Save mpg state for subdomainsSumit Bose2013-06-282-4/+13
| | | | | | The information of a subdomain will use magic private groups (mpg) or not will be stored together with other information about the domain in the cache.
* IPA: read ranges before subdomainsSumit Bose2013-06-281-29/+27
| | | | | | | Since FreIPA will start to support external mapping for trusted domains as well the range type for the domain must be know before the domain object is created. The reason is that external mapping will not use magic private groups (mpg) while algorithmic mapping will use them.
* Replace new_subdomain() with find_subdomain_by_name()Sumit Bose2013-06-285-16/+11
| | | | | | new_subdomain() will create a new domain object and should not be used anymore in the priovder code directly. Instead a reference to the domain from the common domain object should be used.
* Add support for new ipaRangeType attributeSumit Bose2013-06-283-6/+36
| | | | | | | | | Recent versions of FreeIPA support a range type attribute to allow different type of ranges for sub/trusted-domains. If the attribute is available it will be used, if not the right value is determined with the help of the other idrange attributes. Fixes https://fedorahosted.org/sssd/ticket/1961
* Add ipa_idmap_init()Sumit Bose2013-06-283-1/+275
| | | | | | Use the sdap_idmap context for the IPA provider as well. https://fedorahosted.org/sssd/ticket/1961
* Replace SDAP_ID_MAPPING checks with sdap_idmap_domain_has_algorithmic_mappingSumit Bose2013-06-285-14/+38
| | | | | | | | | | Currently the decision if external or algorithmic mapping should be used in the LDAP or AD provider was based on the value of the ldap_id_mapping config option. Since now all information about ID mapping is handled by libsss_idmap the check for this options can be replace with a call which checks the state via libss_idmap. https://fedorahosted.org/sssd/ticket/1961
* Add sdap_idmap_domain_has_algorithmic_mapping()Sumit Bose2013-06-282-0/+62
| | | | | | | This patch implements a wrapper for sss_idmap_domain_has_algorithmic_mapping() for the sdap ID mapping. Fixes https://fedorahosted.org/sssd/ticket/1960
* Allow different methods to find new domains for idmappingSumit Bose2013-06-282-3/+24
| | | | | | | | | | | | | | | | | Currently the range management code is in the generic LDAP provider and can be used by the LDAP and AD provider. New ranges are allocated with the help of a hash value of the domain SID. If the IPA provider cannot find a range for a given domain it cannot allocate a new range on its own but has to look up the idrange objects on the FreeIPA server and use them accordingly. To allow the LDAP, AD and IPA provider to use as much common code as possible a plugin interface, similar to the one used to find the DNS site, to find a missing range would be useful. The default plugin will be used by the LDAP and the AD provider and the IPA provider will implement a plugin to read the data from the server. Fixes https://fedorahosted.org/sssd/ticket/1961
* SDAP IDMAP: Add configured domain to idmap contextSumit Bose2013-06-281-0/+70
| | | | | | To allow libsss_idmap to manage all id-ranges the id-ranges of the domains configured in sssd.conf which are currently unmanaged must be added to libsss_idmap.
* Add now options ldap_min_id and ldap_max_idSumit Bose2013-06-284-0/+8
| | | | | | | Currently the range for Posix IDs stored in an LDAP server is unbound. This might lead to conflicts in a setup with AD and trusts when the configured domain uses IDs from LDAP. With the two noe options this conflict can be avoided.
* SSH: When host is removed from LDAP, remove it from the cache as wellJan Cholasta2013-06-271-1/+8
| | | | https://fedorahosted.org/sssd/ticket/1949
* Fix compilation warningJakub Hrozek2013-06-271-1/+1
|
* AD: Write out domain-realm mappingsJakub Hrozek2013-06-273-165/+10
| | | | | This patch reuses the code from IPA provider to make sure that domain-realm mappings are written even for AD sub domains.
* KRB5: guess UPN for subdomain usersJakub Hrozek2013-06-277-18/+43
|
* AD: kinit with the local DC even when talking to a GCJakub Hrozek2013-06-262-4/+21
| | | | | | | | We tried to use the GC address even for kinit which gave us errors like: "Realm not local to KDC while getting initial credentials". This patch adds a new AD_GC service that is only used for ID lookups, any sort of Kerberos operations are done against the local servers.
* Use forest for GC SRV lookupsSumit Bose2013-06-261-12/+40
| | | | https://fedorahosted.org/sssd/ticket/1973
* Do not switch to credentials everytime.Lukas Slebodnik2013-06-261-4/+69
| | | | | | | | | If user decide to kinit as another user we do not want to switch back to user ccache at another login. We will switch to new ccache if and only if default principal name is the same as current principal name, or there is not any default ccache. https://fedorahosted.org/sssd/ticket/1936
* Every time return directory for krb5 cache collection.Lukas Slebodnik2013-06-262-4/+64
| | | | | | | | Function krb5_cc_get_full_name is called only as a way to validate that, we have the right cache. Instead of returned name, location will be returned from function cc_dir_cache_for_princ. https://fedorahosted.org/sssd/ticket/1936
* fix dead code in fail_over_srv.cPavel Březina2013-06-251-11/+12
| | | | | | | | https://fedorahosted.org/sssd/ticket/1969 The dead code is in fo_discover_servers_primary_done(). By fixing it I have also added a debug message on ret != EOK. This change is done also in fo_discover_servers_backup_done().
* krb5: do not use enterprise principals for renewalsSumit Bose2013-06-251-1/+6
| | | | | | When renewing a ticket we already know the canonical principal hence it is not needed to expand it to an enterprise principal but we can contact the KDC of the corresponding realm directly.
* krb5: do not send pac for IPA users from the local domainSumit Bose2013-06-255-10/+20
| | | | | | | | | | | | | So far we didn't send the PAC of IPA users to the PAC responder during password authentication because group memberships for IPA users can be retrieved efficiently with LDAP calls. Recently patches added PAC support for the AD provider as well and removed the restriction for the IPA users. This patch restores the original behaviour by introducing a new flag in struct krb5_ctx which is only set for the IPA provider. Additionally a different flag is renamed to make it's purpose more clear. Fixes https://fedorahosted.org/sssd/ticket/1995
* Revert "Always send the PAC to the PAC responder"Sumit Bose2013-06-251-18/+20
| | | | This reverts commit d153941864fe481399665be8fe583c9317194a99.
* Fix typo in pack_authtok()Sumit Bose2013-06-241-1/+1

* KRB5: use the right authtok type for renewalsSumit Bose2013-06-241-3/+20
|
* IPA: Do not download or store the member attribute of host groupsJakub Hrozek2013-06-242-2/+0
| | | | | | | | https://fedorahosted.org/sssd/ticket/1806 The IPA provider attempted to store the original value of member attribute to the cache. That caused the memberof plugin to process the values which was really CPU intensive.
* LDAP: Retry SID search based on result of LDAP search, not the return codeJakub Hrozek2013-06-241-2/+13
|
* failover: if expanded server is marked as neutral, invoke srv collapsePavel Březina2013-06-211-0/+7
| | | | | | | | | | https://fedorahosted.org/sssd/ticket/1947 Otherwise we will do the SRV expansion once again: 1. leaving the old servers in server list 2. meta server is not inserted back in the list, the newly found servers are inserted behind meta server, meta server is orphaned and the new servers are forgotten
* collapse_srv_lookup may free the server, make it clear from the APIPavel Březina2013-06-211-6/+9
| | | | https://fedorahosted.org/sssd/ticket/1947
* failover: return error when SRV lookup returned only duplicatesPavel Březina2013-06-211-2/+21
| | | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1947 Otherwise we risk that the meta server is removed from the server list, but without a chance to return, because there may be no fo_server with srv_data = meta. Also if state->meta->next is NULL (it is still orphaned because we try to errornously expand it without invoking collapse first), state->out will be NULL and SSSD will crash. New error code: ERR_SRV_DUPLICATES
* failover: do not return invalid pointer when server is already presentPavel Březina2013-06-211-2/+6
| | | | https://fedorahosted.org/sssd/ticket/1947
* FO: Check the return value of send_fnJakub Hrozek2013-06-211-0/+4

* Fix dp_copy_optionsJakub Hrozek2013-06-211-1/+1
|
* nested groups: do not expect any particular number of groupsPavel Březina2013-06-181-19/+10
|
* nested groups: do not return ENOMEM if num_groups is 0Pavel Březina2013-06-181-6/+10
| | | | | | talloc_realloc(..., 0) calls talloc_free() and returns NULL. If we process group that contains only users, we errornously return ENOMEM.
* Set default realm for enterprise principalsSumit Bose2013-06-171-0/+12
| | | | | | | | | | Enterprise principals require that a default realm is available. To make SSSD more robust in the case that the default realm option is missing in krb5.conf or to allow SSSD to work with multiple unconnected realms (e.g. AD domains without trust between them) the default realm will be set explicitly. Fixes https://fedorahosted.org/sssd/ticket/1931
* Use principal from the ticket to find validation entrySumit Bose2013-06-171-1/+1
| | | | | | | | | If canonicalization or enterprise principals are enabled the realm of the client principal might have changed compared to the original request. To find the most suitable keytab entry to validate the TGT is it better to use the returned client principal. Fixes https://fedorahosted.org/sssd/ticket/1931
* handle ERR_ACCOUNT_EXPIRED properlyPavel Březina2013-06-173-1/+13
| | | | https://fedorahosted.org/sssd/ticket/1953
* Fix allocation checkJakub Hrozek2013-06-171-1/+1

* nested groups: allocate more space if deref returns more membersPavel Březina2013-06-171-0/+21
| | | | https://fedorahosted.org/sssd/ticket/1894
* subdomains: touch krb5.conf when creating new domain-realm mappingsPavel Březina2013-06-161-0/+8
| | | | https://fedorahosted.org/sssd/ticket/1815
* AD: Remove ad_options->auth options referenceJakub Hrozek2013-06-141-1/+0
| | | | | The options are stored in ad_options->auth_ctx->opts, this member was completely unused and confusing.
* AD: Fix segfault in DEBUG messageJakub Hrozek2013-06-141-1/+1
