* IPA: add support for new extdom plugin versionSumit Bose2014-09-301-87/+802
| | | | | | | | | | | | | | | | | | | Initially the extdom plugin was only used to translate SIDs of AD user and groups to names or POSIX IDs. On IPA clients group memberships were resolved with the help of the PAC in the Kerberos ticket which required that the user has logged in at least once. Home directory and the login shell were auto generated. The new version of the extdom plugin can return the complete list of group memberships of a user and the list of all members of a group. Additionally the gecos field, home directory and login shell are returned together with an optional list of key-value pairs for arbitrary data which is written unmodified to the cache.

| | | | | | | | | | | https://fedorahosted.org/sssd/ticket/2412 Even though AD trusts often work with POSIX attributes which are normally not replicated to GC, our group lookups are smart since commit 008e1ee835602023891ac45408483d87f41e4d5c and look up the group itself using the LDAP connection and only use the GC connection to look up the members.

* Add alternative objectClass to group attribute mapsMichal Zidek2014-09-151-1/+2

* IPA: handle searches by SID in apply_subdomain_homedirJakub Hrozek2014-08-191-4/+9
| | | | | | | | | | | | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/2391 apply_subdomain_homedir() didn't handle the situation where an entity that doesn't match was requested from the cache. For user and group lookups this wasn't a problem because the negative match was caught sooner. But SID lookups can match either user or group. When a group SID was requested, the preceding LDAP request matched the SID and stored the group in the cache. Then apply_subdomain_homedir() only tried to search user by SID, didn't find the entry and accessed a NULL pointer. A simple reproducer is: $ python >>> import pysss_nss_idmap >>> pysss_nss_idmap.getnamebysid(group_sid) The group_sid can be anything, including Domain Users (XXX-513) Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>

* LDAP: Detect the presence of POSIX attributesJakub Hrozek2014-02-121-1/+1
| | | | | | | | | | | | | | | | | | | When the schema is set to AD and ID mapping is not used, there is a one-time check ran when searching for users to detect the presence of POSIX attributes in LDAP. If this check fails, the search fails as if no entry was found and returns a special error code. The sdap_server_opts structure is filled every time a client connects to a server so the posix check boolean is reset to false again on connecting to the server. It might be better to move the check to where the rootDSE is retrieved, but the check depends on several features that are not known to the code that retrieves the rootDSE (or the connection code for example) such as what the attribute mappings are or the authentication method that should be used.
