search for: auth_request_set_login_username

Using kmail with PLAIN authentication worked fine with beta3 but trying it with beta4 authentication fails. This is because kmail sends "username \0 username \0 password" in the authorization token and the new code to call auth_request_set_login_username() when supplied an authid must be returning failure (certainly commenting this code out returns to the beta3 behaviour of successfully authenticating). I had a quick look at the routine to see why it might be failing but didn't really work out what its supposed to do. cheers mark
