Public bug reported:

"wbinfo -u" and "wbinfo -g" should list domain users and groups, but report nothing.
"getent group <domain-group>" returns only the first 3 fields of the group database, but not the group members.

Firefox SSO with ntlm_auth is not working as it used to. Most of the
time the access to servers that use ntlm_auth is rejected, but somtimes
it is granted.

In the winbind log-file log.wb-<DOMAIN> are error messages like the
following (when running winbindd with debuglevel 4):

[2016/04/22 12:41:20.439812,  3] ../source3/libads/ldap.c:980(ads_do_paged_search_args)

Befor the update to winbind 4.3.8, my setup has been working for several
years without any problems.
