No modern protocol should care. The target username should be transmitted as 
part of the application protocol - GSSAPI does authentication, not authorization 
or user name mapping. Yes, MIT krb5 (not GSSAPI) supports hacks using 
auth_to_local and auth_to_local_names, but only if you call 
krb5_aname_to_localname(), which is deprecated. I suspect mod_krb is using this 
deprecated function.

What worries me is that the native realm _is_ stripped. It shouldn't be. I'm not 
sure why gssapi_server_mech_step() does so.
