Hi guys, I have a pretty basic question about how cross-realm authentication works with ssh. Can kerberized logins work when your TGT is not from the default realm (as specified by /etc/krb5.conf)
I set up 2 MIT KDCs using Ubuntu server (dapper) each in a different realm (say REALM1 and REALM2), and configured them for cross-realm authentication. I put my service principal for a test client (host/[EMAIL PROTECTED]) in one KDC and an account ([EMAIL PROTECTED]) in the other. On my client (also running the same version of Ubuntu with libpam_krb5), I configured ssh for gssapi, and installed the keytab with the principal "host/[EMAIL PROTECTED]". I was able to "kinit [EMAIL PROTECTED]" and ssh to cselin12.REALM1 and login automatically when my default realm (in /etc/krb5.conf) was set to be REALM2. However, if I set it to be REALM1, it did not work and I get prompted for a password. This is not that big a deal for us, but if we wanted to have different users logging in to the same machine, some whose account principals only existed in REALM1 and some whose account principals only existed in REALM2, would there be a way to do that? Many thanks for any help, Rohit ________________________________________________ Kerberos mailing list Kerberos@mit.edu https://mailman.mit.edu/mailman/listinfo/kerberos
