Interesting.  Yes, there are several OIDs exported by libgss on
OpenIndiana, but none I can find quite like gss_mech_krb5.
Here is a search showing the closest ones:
http://src.illumos.org/source/search?q=GSS_C_NT_USER_NAME&project=illumos-gate

The OID you want is here, but not exported by the library:
http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/gssapi/mechs/krb5/mech/gssapi_krb5.c#118

Do you have any more specific guidance on writing an autoconf test
that answers "does a header or library provide gss_mec_krb5?"

Thanks,
Gordon
