The Error message was "unknown error, help" or very nearly. However, as the system that it was to be installed on is a production server, my 'boss' decided that we shouldn't be attempting to do development work of installing SaMBa on a VM to implement Active Directory Single-Sign-On.
When playing with your own systems at home... the line between production and development can get a little... blurry. Thanks for the information though, folks. Anathae
