#951 sssd 1.6.0 fails to find groups with OpenLDAP server

Created 5 years ago by dpiddock

1.6.0 is failing to find groups. When a user logs in, sssd queries for which group they are a member of with:

(&(memberUid=testuser)(objectClass=posixGroup)(cn=*)(gidNumber>=1))

In OpenLDAP (and possibly other LDAP servers) the gidNumber is not an ORDERING attribute. This search is returning no results, so sssd thinks the user has no groups. Removing (gidNumber>=1) or changing it to (!(gidNumber=1)) gets the list of groups returned. I've attached a patch to do the latter in the two obvious places in the code (ldap_id.c and sdap_async_accounts.c.)

I'm not sure if the two uses of >= in providers/ldap/ldap_id_enum.c also needs looking at. Their existence doesn't seem to be causing me problems or I'm not hitting those blocks due to the if statements.

(setting version blank as 1.6.0 isn't listed yet)

This is a regression caused by b00113f8d5fcaf405364dfb5bc28a8076b6c10bd

I only tested with 389 where gidNumber has ORDERING apparently.

This needs fixing in the 1.5 branch as well.
