PAM only addresses the server side of authentication. For example, one
of the powerful features of Kerberos is ticket forwarding. It requires
the client application understand Kerberos (or GSSAPI) well enough to
actually forward the cached credentials rather than a username &
password. A server-side-only PAM module won't provide features like
this. This, in a Kerberos environment, pam_krb5 is a stop-gap measure.

I like PAM. However, pam_krb5 doesn't do what you seem to think it does


Why look for meaning where there is none?  Would you follow a path you know 
leads nowhere?
