Ok that is relatively good progress.

Indeed, your AuthMessage appears wrong: it should start with n=..., so
you have to remove the 'n,,' part. Check the document:
AuthMessage := client-first-message-bare + "," +
server-first-message + "," +
username = "n=" saslname
;; Usernames are prepared using SASLPrep.
reserved-mext = "m=" 1*(value-char)
;; Reserved for signalling mandatory extensions.
;; The exact syntax will be defined in
;; the future.
username "," nonce ["," extensions]
