* LDAP: Filter out multiple entries when searching overlapping domainsJakub Hrozek2015-09-224-20/+116
| | | | | | | | | | In case domain overlap, we might download multiple objects. To avoid saving them all, we attempt to filter out the objects from foreign domains. We can only do this optimization for non-wildcard lookups. Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>

* LDAP: imposing sizelimit=1 for single-entry searches breaks overlapping domainsJakub Hrozek2015-09-222-13/+0
| | | | | | | | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/2723 In case there are overlapping sdap domains, a search for a single user might match and return multiple entries. For instance, with AD domains represented by search bases: DC=win,DC=trust,DC=test DC=child,DC=win,DC=trust,DC=test A search for user from win.trust.test would be based at: DC=win,DC=trust,DC=test but would match both search bases and return both users. Instead of performing complex filtering, just save both users. The responder would select the entry that matches the user's search. Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>

However, there was a small bug - the is_offline internal sdap_id_op flag was still being set. As a consequence, the error code from the connection was ignored and EAGAIN was always returned.

* Download complete groups if ignore_group_members is set with tokengroupsJakub Hrozek2015-05-311-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resolves: https://fedorahosted.org/sssd/ticket/2644 When tokenGroups are enabled, we save groups using their SID as the RDN attribute during initgroups() and later, if the groups is requested and saved again with the full name, remove the original and save the new group entry. Saving the new group entry would break if ignore_group_members is also set, because the new group entry would lack the "member" attribute, so the member/memberof links between the new group and the user entry wouldn't be established again. This patch changes the initgroups processing so that the full group object is fetched when initgroups is enabled but together with ignore_group_members. This solution imposes some performance impact, because instead of one search for tokenGroups we also need to resolve the groups. The more systematic solution would be to get rid of removing the group entry as described in https://fedorahosted.org/sssd/ticket/2656 To reproduce the bug, set: ignore_group_members = True with a backend that uses: id_provider = ad Then run: $ id aduser@ad_domain.com $ id aduser@ad_domain.com Reviewed-by: Sumit Bose <sbose@redhat.com>
