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.

      Diffie-Hellman Security

      -----------------------

      To secure your web server, the `Guide to Deploying Diffie-Hellman for TLS`_

      contains important information worth reading. This link contains some good

      `secure Apache configuration`_ examples.

      To secure your deployment of Diffie-Hellman, configure the following:

      1. Generate a strong Diffie-hellman group, 2048-bit or stronger.

      .. code-block:: bash

          # to generate your dhparam.pem file, run in the terminal

          openssl dhparam -out /etc/apache/ssl/dhparam.pem 2048

      2. Configure your server to only use modern, secure cipher suites in the

         virtual hosts configuration file.

      .. code-block:: apache

          # Set the protocol to only use modern, secure cipher suites.

          SSLProtocol             all -SSLv2 -SSLv3

          SSLHonorCipherOrder     on
