OpenSSH 2.9p2+Kerberos5 on RH7.1 fails

[Eric Seppanen]

I've been installing OpenSSH 2.9p2 onto several RedHat Linux machines,
after compiling in the GSSAPI/Kerberos5 patch from here:
http://www.sxw.org.uk/computing/patches/openssh.html

I've been using ssh both to let users in via passwords and Kerberos
tickets, and both have been working fine...

except for one irritating machine, which (for no good reason I can see)
fails when using kerberos tickets.  (it works fine when using
passwords.)  This is a Red Hat 7.1 machine, and the failure is:
(the user sees:)
  [eds at ike eds]$ ssh hulk
  Connection closed by 208.24.105.2

(the server log reads:)
  Jul 24 16:37:41 hulk sshd[25687]: fatal: gss_accept_context died

(if I run sshd -d I see:)

I've built source and binary RPMS.  Anyone interested can find them at

Anyone have any ideas what's wrong?
