* LDAP: Detect the presence of POSIX attributesJakub Hrozek2014-02-121-4/+46
| | | | | | | | | | | | | | | | | | | 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.

* AD: Establish cross-domain memberships after enumeration finishesJakub Hrozek2014-01-291-11/+377
| | | | | | | | | | | | | | | | Because domain enumeration currently works for each domain separately, the code has to establish cross-domain memberships after all domains are enumerated. The code works as follows: 1) check if any *sub*domains were enumerated. If not, do nothing 2) if any of the groups saved had more original members than sysdb members, check if members of these groups can be linked now that all users and groups are saved using the orig_member attribute of the group matched against originalDN member of the user.

* AD: cross-domain membership fixSumit Bose2013-12-191-17/+2
| | | | | | | | | | | | | | | | | | | A recent patch directed all call related to group membership lookups to the AD LDAP port to fix an issue related to missing group memberships in the Global Catalog. As a side-effect it broke cross-domain group-memberships because those cannot be resolved by the connection to the LDAP port. The patch tires to fix this by restoring the original behaviour in the top-level lookup calls in the AD provider and switching to the LDAP port only for the LDAP request which is expected to return the full group membership. Additionally this patch contains a related fix for the tokenGroups with Posix attributes patch. The original connection, typically a Global Catalog connection in the AD case is passed down the stack so that the group lookup after the tokenGroups request can run over the same connection.
* AD: Don't mark domain as enumerated twiceJakub Hrozek2013-12-181-12/+0
| | | | | The domain was already marked as enumerated using sysdb_set_enumerated in the enumeration request itself.
* AD: use LDAP for group lookupsSumit Bose2013-12-131-2/+18
| | | | | | | | | | | | | | | | The group memberships cannot be reliable retrieved from the Global Catalog. By default the memberOf attribute is not replicated to the GC at all and the member attribute is copied from the local LDAP instance to the GC running on the same host, but is only replicated to other GC instances for groups with universal scope. Additionally the tokenGroups attribute contains invalid SIDs when used with the GC for users from a different domains than the GC belongs to. As a result the requests which tries to resolve group-memberships of a AD user have to go to a LDAP server from the domain of the user. Fixes https://fedorahosted.org/sssd/ticket/2161 and https://fedorahosted.org/sssd/ticket/2148 as a side-effect.

* ad: shortcut if possible during get object by ID or SIDPavel Březina2013-10-301-0/+96
| | | | | | | | | | When getByID or getBySID comes from responder, the request doesn't necessarily have to contain correct domain, since responder iterates over all domains until it finds a match. Every domain has its own ID range, so we can simply shortcut if domain does not match and avoid LDAP round trip. Responder will continue with next domain until it finds the correct one.
* AD: fall back to LDAP if GC is not available.Lukas Slebodnik2013-10-251-0/+11

| | | | | | | | | Related: https://fedorahosted.org/sssd/ticket/2070 Since we are recommending to configure the POSIX attributes so that they are replicated to the Global Catalog, we can start connecting to the GC by default even for local users. If the object is not matches in the GC, there is a possibility to fall back to LDAP.
* AD: Failure to get flat name is not fatalJakub Hrozek2013-09-201-3/+0
| | | | | | | | | https://fedorahosted.org/sssd/ticket/2067 Some AD or AD-like servers do not contain the netlogon attribute in the master domain name. Instead of failing completely, we should just abort the master domain request and carry on. The only functionality we miss would be getting users by domain flat name.
* AD: Download master domain info when enumeratingJakub Hrozek2013-09-181-0/+185
| | | | | | | | | | https://fedorahosted.org/sssd/ticket/2068 With the current design, downloading master domain data was tied to subdomains refresh, triggered by responders. But because enumeration is a background task that can't be triggered on its own, we can't rely on responders to download the master domain data and we need to check the master domain on each enumeration request.

* AD ID lookups - choose GC or LDAP as appropriateJakub Hrozek2013-06-071-1/+262
| | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1557 Some lookups should be performed from GC only -- for example trusted users are only present in the Global Catalog, while some lookups should be performed from LDAP only as not all objects or attributes are replicated to Global Catalog. This patch adds a generic failover mechanism for identity lookups in the AD provider that allows to choose the appropriate source and even fail over to the other source if available.
* LDAP: Pass in a connection to ID functionsJakub Hrozek2013-06-071-1/+1
| | | | | | | Instead of using the default connection from the sdap_id_ctx, allow the caller to specify which connection shall be used for this particular request. Again, no functional change is present in this patch, just another parameter is added.
