[Samba] authentication issue moving from Samba 4.11.x to 4.13.14

[Gaiseric Vandal]

LDAP is used for user and group lookups at the Unix/Linux level.   This 
includes nfs and ssh.  The authentication itself is typically 
kerberos.   Presumably if nsswitch.conf pointed to winbind but not ldap 
it everything would continue to work.
