By default when TapeTrack Command Line programs send passwords to the TapeTrack Framework Server they are first MD5 hashed, and then AES encrypted along with the rest of the data that is sent with the login request.
When a TapeTrack User uses Windows Active Directory authentication, TapeTrack must be able to AES decrypt the login request and then send an unhashed password to Active Directory.
When the Environmental Variable TMSSNOMD5 is set the TapeTrack low level API will not MD5 hash the password and instead send the actual password (AES encrypted) to the TapeTrack Framework Server.
The value of the Environmental Variable is not consequential.
