ksu: Incorrect net address while geting credentials from kdc

[Adams Kevin J]

Dear kerberos helpers,

I have some multihomed Linux (krb 1.2.5) and AIX (krb 1.2.2) hosts, with the
KDC on AIX.

If I kinit -A from Linux, and telnet -F to AIX, the forwarded ticket always
has an address. On Linux the ticket does not have an address, but the
forwarded ticket on AIX does.

Then, when I ksu on the AIX host with the forwarded ticket, I get, "ksu:
Incorrect net address while geting credentials from kdc". 

Since these are multihomed hosts, the forwarded ticket has an address
different than what hostname resolves to on AIX. Also, the forwarded ticket
includes only the address I used to telnet too, and not the other
interfaces. If I then kinit on AIX, the ticket includes all interfaces and
the ksu works.

The forwarded ticket looks the same whether I kinit or kinit -A.

I need to telnet to a specifice interface other than what hostname resolves
too.

Why does a forwarded ticket include an address when the original ticket does
not?

How do I get around this.

Thanks,
Kevin
