Description Dmitri Pal 2013-11-14 14:29:32 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/2148

If the DNS names of member domains in an AD forest have a parent-child relation ship, e.g. forest.ad, child.forest.ad, grandchild.forest.ad, the LDAP sub-trees in the GC for the child domains are children of the forest root LDAP tree. Hence a subtree search in the forest root tree will find results in the child domains as well.

Since there are user and group names which are present in all AD domains e.g. a search for 'Domain Users' will return multiple matches. Currently this is not expected by the generic SSSD LDAP code and the following can be found in the logs:
