sssd_be crashing with nested ldap groups contain a dangling member

Solution Unverified - Updated -


Whenever a lookup is done (for example opening an SSH session or running groups username) to figure out a users' group membership and that particular user is a member of a ldap group that is nested in another ldap group, sssd_be aborts with the following logged to /var/log/messages:

kernel: sssd_be[32294]: segfault at 0 ip (null) sp 00007fff4a2f2eb8 error 14 in sssd_be[400000+87000]

The issue occurs only when SSSD tried to resolve ldap groups which contains a dangling member

I do make use of the ldap_schema = rfc2307bis and ldap_group_member = uniqueMember options
