Indeed.  If the Solaris folk feel that getupeercred() is insecure,

The Solaris security & kernel folks do, actually. However, there's no question that TRUST is inherently insecure, and that's what people
 are going to use if they can't get IDENT to work.

I'd be *very* interested in how they come to that assessment. I'd have
thought that the only alternative to getpeereid/getupeercred is
password-based or certificate-based authenticated - which seem *less*
secure because a) they also rely on the client having the correct uid
or gid (to read the password/private key), plus b) the risk of the
password/private key getting into the wrong hands.

How is that sort of authenticated handled by services shipping with solaris?

posix-ish view of the world...
