We don't know because we're letting the client and server negotiate the scheme.
We could iterate over a known list instead.

I did some testing and it turns out that both GSSAPI and GSS-SPNEGO call
SASL_CB_USER, but successful authentication depends on this callback returning
an error. DIGEST-MD5 also calls this one, followed by SASL_CB_AUTHNAME and
SASL_CB_PASS.

SASL_CB_USER appears to be used for supplying a proxy username, which is not
supported by all schemes.
