auth: don't break hashing in case of user with empty password....
auth: don't break hashing in case of user with empty password. In some cases such as LDAP user created via external scripts users might set the passwords to empty. The hashing uses the md5(password_hash) to store reference to detect password changes and forbid using the same password. In case of pure LDAP users this is not valid, and we shouldn't raise Errors in such case. This change makes it work for empty passwords now.
