AIX 4.3-to-5.2 breaks OpenSSH_3.8p1 gssapi

Subject: AIX 4.3-to-5.2 breaks OpenSSH_3.8p1 gssapi

On our current AIX 4.3 clients, kinit-ssh command sequences provide
logins without passwords.  The identical OpenSSH_3.8p1 client fails
under AIX 5.2 with error "Cannot resolve network address for KDC in
requested realm".

Has anyone seen this?  This is not an /etc/krb5.conf issue - klist
shows a good ticket, so the kinit command found the appropriate kdc,
but ssh-gssapi can't


ssh -V

OpenSSH_3.8p1, SSH protocols 1.5/2.0, OpenSSL 0.9.7c 30 Sep 2003

ssh -vvv . . .

debug3: remaining preferred: hostbased,publickey,keyboard-interactive,password
debug3: authmethod_is_enabled gssapi-with-mic

debug2: we sent a gssapi-with-mic packet, wait for reply
