[Samba] LDAP Supplementary Groups not recognised

[MICHAEL BROWN]

I have this problem as well, however, my groups ARE recognized up to about 80 users in any group.  If I put more than 80 users in a group, Samba does not authenticate.  This DOES NOT happen on 2.2.7a but does on 2.2.8 and 2.2.8a.  I am running Redhat 8 with ldapsam on openldap database.  If I run getent, etc. the users do show what group they are a member of but Samba just does not authenticate over the 80 users.  I have other applications that use the same LDAP database per user/group setup and works just fine so it does not seem to be linked to openldap.
