By the way, I think it's a bug that your server advertised the
SASL/EXTERNAL mechanism here; that mech should only be offered when
there is actually an external security system in place (e.g. IPSEC or
TLS). It appears this was a plain, unprotected connection. A mech
shouldn't be listed in the supportedSASLmechanisms list if requesting it
will in fact fail with "no mechanism available"...
