Restore the BlackBerry MDS Connection Service configuration files

You can use the BlackBerry® MDS Connection Service configuration files, MdsLogin.conf and krb5.conf, to configure how the BlackBerry MDS Connection Service authenticates BlackBerry devices with content servers that use NTLM or Kerberos™. The BlackBerry MDS Connection Service configuration files are located in <drive>:\Program Files\Research In Motion\BlackBerry Enterprise Server\MDS\Servers\Instance\config.

When you upgrade a BlackBerry® Enterprise Server Express, the setup application creates new MdsLogin.conf or krb5.conf files and creates backup versions of the old BlackBerry MDS Connection Service configuration files in the same location. If you changed the MdsLogin.conf or krb5.conf files before you perform the upgrade, you should restore the backup versions of the files so that the BlackBerry MDS Connection Service can authenticate BlackBerry devices with the content servers that use NTLM or Kerberos.
