If I can help, I'm happy to answer questions here or off-list.

Are you trying to pass the username/password to the server, or 
*authenticate* with the username/password?

If the latter, there are protocols like SRP which let you do mutual 
authentication with a password without sending it over the network - 
basically, each side proves to the other that it knows the password, 
without exposing the password in any way.

So you get strong mutual authentication, but you don't have to mess with 
certs.  TLS Lite provides this, if you're interested.
