autofs-5.1.1 - fix error handling on ldap bind fail
From: Ian Kent <raven@themaw.net>
When calling unbind_ldap_connection() if a sasl connection is
being used then autofs_sasl_unbind() should be called and not
ldap_unbind_ext(), otherwise the ldap connection release code
could be called twice.
So, in unbind_ldap_connection() check if a sasl connection is in
use and unbind it if it is otherwise call ldap_unbind_ext() to
release the ldap connection.
Signed-off-by: Ian Kent <raven@themaw.net>
