Surely the client is not passing either of those into the core of rxgk but
instead is passing in the results of gss_import_name(), no?  So the client
(be it aklog or something else) can use whatever OID is most appropriate
when calling gss_import_name() for what it's attempting to do.  Or do I
misunderstand what gss_import_name() can do in this situation?

depending on whether the user has forced the server principal to a
particular value, but it's not tested with multimechanism GSSAPI.  I would
expect that forcing the principal name wouldn't work if the GSSAPI
mechanism chosen ended up not being Kerberos, but that's fine.
