Seem to be unable to set user and password to anything other than the default

Seem to be unable to set user and password to anything other than the default. Even if I just change (password - business to busines) on both client and server it fails with Authentication error 401. Am I missing something ?

on client I set:
RemoteDBDatabase.UserName := 'remotedb'
RemoteDBDatabase.Password := 'business'

on server I set:
RemoteDBServer.UserName := 'remotedb';
RemoteDBServer.Password := 'business';

You must do it before you start and/or restart the server.

Thanks for the reply, although that was not the issue, it was however something silly on my part. All working now with different user and pass
