Update of /var/lib/cvs/dovecot/doc
In directory talvi:/tmp/cvs-serv21165/doc

Modified Files:
	dovecot-ldap.conf 
Log Message:
LDAP code changes: If auth binds are used, bind back to the default dn
before doing a search. Otherwise it could fail if user gave an invalid
password. Initial binding is now also done asynchronously. Reconnecting to
LDAP server wasn't working with auth binds. Use pass_attrs even with
auth_bind=yes since it may contain other non-password fields also. Updated
dovecot-ldap.conf to contain sasl_bind settings and reflect these changes.
