2013-05-02Use struct to hold different types of request parametersSumit Bose4-26/+48
Currently the POSIX ID or the user name are passed in different parameters to some calls. The method will get cumbersome and error-prone if new parameters like, e.g. the SID, are added. This patch adds a union to hold the different kind of parameters.
2013-05-02Remove unused attribute listSumit Bose3-14/+1
2013-05-02Add sss_ncache_set_sid() and sss_ncache_check_sid()Sumit Bose2-0/+31
Two new calls are added to allow to add SID based lookups to the negative cache.
2013-05-02sysdb: add sysdb_search_object_by_sid()Sumit Bose2-0/+62
The patch add a new sysdb to find objects based on their SID. Currently only the basic attributes needed to map SIDs to POSIX IDs and names are requested, but this list can be extended for future use cases.
2013-05-02Add responder_get_domain_by_id()Sumit Bose2-0/+52
This new call is similar to responder_get_domain() but uses the domain SID as search parameter. Since the length of the stored domain SID is used in the comparison, SIDs of users and groups and be used directly without stripping the RID component. The functionality is not merged into responder_get_domain() to allow to calculate the timeout correctly and return a specific error code if the entry is expired.
2013-05-02Add idmap context to nss contextSumit Bose2-0/+22
This allows the nss responder to use libsss_idmap to convert between different SID representations.
2013-05-02Add two new request types to the data-provider interfaceSumit Bose3-1/+11
The patch adds two new request types for SID related requests. The first one is used if a SID is given and the corresponding object should be found. The second one can be used if the SID for an object is requested but it is not clear if the object is a user or a group.
2013-05-02Add secid filter to responder-dp protocolSumit Bose5-4/+37
This patch add a new filter type to the data-provider interface which can be used for SID-based lookups.
2013-05-02LDAP: always store SID if availableSumit Bose2-33/+58
Currently the string representation of a SID is only stored in the cache for debugging purpose if SID based ID-mapping is used. This patch unconditionally stores the SID if available to allow SID-to-name mappings from the cache.
2013-05-02responder_get_domain(): remove timeout calculationSumit Bose1-10/+1
The current timout calculation code in responder_get_domain() is flawed and I think it always was. I removed the related code because - it currently has no effect, a match is returned even if it is expired - that callers do not have any code to handle expired domains.
2013-05-02responder_get_domain: do not return disabled domainsSumit Bose1-0/+4
Recent refactoring introduced to concept of disabled domains, i.e. domains which does not exists anymore. responder_get_domain() should not return disabled domains.
2013-05-02Remove unused TALLOC_CTX from responder_get_domain()Sumit Bose11-20/+16
Recent refactoring removed the need to copy the domain info data of sub-domains because the related objects will not be removed from memory anymore.
2013-05-02dns srv plugin: compare domain names case insensitivePavel Březina1-1/+1
2013-05-02DNS sites support - add AD SRV pluginPavel Březina9-5/+877
https://fedorahosted.org/sssd/ticket/1032
2013-05-02add sss_ldap_encode_ndr_uint32Pavel Březina2-0/+17
Converts uint32 to a string value that is suitable for octed string attributes.
2013-05-02sdap: add sdap_connect_host requestPavel Březina2-0/+201
Create connection to specified LDAP server without using any failover stuff.
2013-05-02IPA SRV plugin: improve debuggingPavel Březina1-0/+6
2013-05-02IPA SRV plugin: use fo_discover_servers requestPavel Březina1-105/+20
2013-05-02add fo_discover_servers requestPavel Březina2-1/+254
This request takes discovery domain for primary servers and other domain for backup servers and returns list of primary and backup servers. If primary domain is not reachable, it returns servers found in backup domain as primary servers.
2013-05-02Display the last grace warning, tooJakub Hrozek2-3/+3
Due to a comparison error, the last warning when an LDAP password was in its grace period was never displayed. https://fedorahosted.org/sssd/ticket/1890
2013-04-29Add override_homedir.xml to po4a.cfgSumit Bose1-0/+1
Every man page source which should be translated must be listed in po4a.cfg. Please remember to add a line whenever a new man page or a new include file is created
2013-04-29Only try to relink ghost users if we're not enumeratingJakub Hrozek2-8/+17
https://fedorahosted.org/sssd/ticket/1893 When SSSD is not enumerating (which is the default), we are trying to link any "ghost" entries with a newly created user entry. However, when enumeration is on, this means a spurious search on adding any user.
2013-04-29libsss_idmap: function to calculate rangeMichal Zidek5-116/+341
Calculation of range for domains is moved from sdap_idmap code to sss_idmap code. Some refactoring have been done to allow this move. https://fedorahosted.org/sssd/ticket/1844
2013-04-29selinux: if no domain matches, make the debug message louderJakub Hrozek1-3/+3

2013-04-26DB: Switch to new libini_config APIOndrej Kos7-238/+707
https://fedorahosted.org/sssd/ticket/1786 Since we need to support the old interface as well, the configure scritp is modified and correct ini interface is chosen.
2013-04-24sudo client: remove dead codePavel Březina1-8/+0
https://fedorahosted.org/sssd/ticket/1889 Fixes two minor coverity issues.

2013-04-23Add exit status section to sss_ssh_* man pagesJan Cholasta2-0/+16
2013-04-22Allow usage of enterprise principalsSumit Bose16-7/+93
Enterprise principals are currently most useful for the AD provider and hence enabled here by default while for the other Kerberos based authentication providers they are disabled by default. If additional UPN suffixes are configured for the AD domain the user principal stored in the AD LDAP server might not contain the real Kerberos realm of the AD domain but one of the additional suffixes which might be completely randomly chooses, e.g. are not related to any existing DNS domain. This make it hard for a client to figure out the right KDC to send requests to. To get around this enterprise principals (see http://tools.ietf.org/html/rfc6806 for details) were introduced. Basically a default realm is added to the principal so that the Kerberos client libraries at least know where to send the request to. It is not in the responsibility of the KDC to either handle the request itself, return a client referral if he thinks a different KDC can handle the request or return and error. This feature is also use to allow authentication in AD environments with cross forest trusts. Fixes https://fedorahosted.org/sssd/ticket/1842
2013-04-21Refactoring: remove duplicated code in nss responderSumit Bose2-622/+240
Different user and group lookup requests used nearly identical code, this patch unifies some of the related code paths.
2013-04-21Fix and rename get_my_domain_data()Sumit Bose3-12/+14
The task of get_my_domain_data() is to read some information about the configured domain from the cache. While the sysdb interface was redesigned some changes changed the behaviour so that the data of the domain of the current request was read. If this domain is a sub-domain the wrong data was read. As a result group-memberships of the configured domain were not taken into account. The original code didn't made it easy to see that always the parent domain should be used here, because there was no comment indication this and the function name get_my_domain_data() didn't made it clear either. Additionally to fixing the issue this patch also adds a comment and rename the function to get_parent_domain_data(). Fixes https://fedorahosted.org/sssd/ticket/1888
2013-04-19Convert the simple access check to new error codesJakub Hrozek1-9/+17
https://fedorahosted.org/sssd/ticket/453 It makes sense to keep using the boolean for access granted/denied, but when the user/group is not found, the request would now return ERR_ACCOUNT_UNKNOWN
2013-04-19LDAP: do not invalidate pointer with realloc while processing ghost usersJakub Hrozek1-3/+13
https://fedorahosted.org/sssd/ticket/1799 One peculiarity of the sysdb_attrs_get_el interface is that if the attribute does not exist, then the attrs array is reallocated and the element is created. But in case other pointers are already pointing into the array, the realloc might invalidate them. Such case was in the sdap_process_ghost_members function where if the group had no members, the "gh" pointer requested earlier might have been invalidated by the realloc in order to create the member element.
2013-04-18tests: Fix the order of key/valuesJakub Hrozek1-2/+3
2013-04-17Make leak checks usable in tests that do not utilize checkJakub Hrozek12-138/+237
* Remove check-specific failure reporting from common_check.c * Check-specific abstraction over memleak checks * Rename common_check.c to leak_check.c
2013-04-17Inform about function duplication.Michal Zidek2-0/+6
sss_mc_set_recycled is a static function, that should not be used outside nsssrv_mmap_cache.c. The sss_cache tool is an exception, because in the case when sssd is not running, sss_cache must invalidate the memory cache file. That is why sss_mc_set_recycled was copied to the tools_mc_util.c (as helper function for sss_memcache_invalidate function). It was duplicated to allow this function to remain static (and invisible to any .h files), so that it is not used anywhere else. Wrong usage of this function might cause race conditions and corrupt the cache. I'll add comments about the duplication to the code.
2013-04-15Fix simple access group control in case-insensitive domainsJakub Hrozek2-18/+11
https://fedorahosted.org/sssd/ticket/1713 In the simple access provider, we need to only canonicalize user names when comparing with values in the ACL, not when searching the cache. The sysdb searches might do a base search with a DN constructed with the username which fails if the username is lower case.
2013-04-15sss_cache: Remove annoying messagesMichal Zidek1-8/+6
When requested entry was not found in one domain, an ERROR message was written to the user even if the entry was found in the next domain and deleted properly.

2013-04-12Confusing error messages for invalid sssd.confAriel Barria1-9/+11
https://fedorahosted.org/sssd/ticket/1625 Amending errors messages and add other error codes to be more specific and avoid confusion.
2013-04-12Fix krbcc dir creation issue with MIT krb5 1.11Lukas Slebodnik2-11/+61
In krb5-libs >= 1.11, function krb5_cc_resolve verify if credential cache dir exists. If it doesn't exist, than it will be created with process permissions and not user permissions. Function cc_residual_is_used has already checked for non existing directory, but it wasn't considered to be a failure and therefore next call of krb5_init_context will create directory with wrong permissions. Now if directory doesn't exist, it will be handled like there was not ccache attribute in sysdb cache. We also check if "primary" file in ccache directory has right permissions. But we ignore missing "primary" file. https://fedorahosted.org/sssd/ticket/1822
2013-04-10DNS sites support - add IPA SRV pluginPavel Březina8-5/+397
https://fedorahosted.org/sssd/ticket/1032
2013-04-10DNS sites support - use SRV DNS lookup plugin in all providersPavel Březina3-0/+29
https://fedorahosted.org/sssd/ticket/1032 We set a plugin during an initialization of ID provider, which is an authoritative provider for a plugin choice. The plugin is set only once. When other provider is initalized (e.g. id = IPA, sudo = LDAP), we do not overwrite the plugin. Since sssm_*_id_init() is called from all module constructors, this patch relies on the fact, that ID provider is initialized before all other providers.
2013-04-10DNS sites support - replace SRV lookup code with a plugin callPavel Březina1-258/+73
https://fedorahosted.org/sssd/ticket/1032 Removes hard coded SRV lookup code with a plugin call. This patch breaks SRV lookups as there is currently no plugin in use. It is fixed in next patch.
2013-04-10fail over - add function to insert multiple servers to the listPavel Březina1-10/+101
2013-04-10DNS sites support - SRV DNS lookup pluginPavel Březina4-0/+521
https://fedorahosted.org/sssd/ticket/1032 This plugin mimics the current behaviour. If discovery_domain is set it is the only domain that is tried. If discovery_domain is not set, we try to autodetect domain first and if that fails or SRV lookup on this domain fails, we fallback to SSSD domain name.
2013-04-10DNS sites support - SRV lookup plugin interfacePavel Březina7-0/+139
https://fedorahosted.org/sssd/ticket/1032 Introduces two new error codes: - ERR_SRV_NOT_FOUND - ERR_SRV_LOOKUP_ERROR Since id_provider is authoritative in case of SRV plugin choise, ability to override the selected pluging during runtime is not desirable. We rely on the fact that id_provider is initialized before all other providers, thus the plugin is set correctly.
