You normally authenticate by getting the good password from LDAP and
then checking that the password is correct. This warning tells you that
it wasn't able to get the password from LDAP.

If you are authenticating by binding to LDAP as the supplied user, then
you don't need to get the password, so this message doesn't matter.

Ignore it.
