LDAP user authentication does not work when using Samba 4 as LDAP backend. Samba 4 (as well as MS AD) returns referrals (search continuations) for some objects.
LDAPv3 does not specify which credentials should be used for the search continuations. libldap tries to anonymous bind and do the search continuations, which fails with
Samba 4 (as well as MS AD).
Kolab 16 will fail while authenticating with ldap.OPERATIONS_ERROR and the error message 00002020: Operation unavailable without authentication
The submitted patch is supposed to be used with
in /etc/ldap.conf and should not affect any other situations.
Eventually setting LDAP option via
would be an option too, but i can't test at the moment, if there is any impact on non Samba 4 setups.
The change in wallace addresses the same problem, as i got
