Hi All
I have a trust between my Windows 2003 AD (HHK.DK) and my RHEL5 MITKerberos (CBS.DK).
On the Windows machines I have:
HKLM\SYSTEM\CurrentControlSet\Control\Lsa\Kerberos\Domains\CBS.DK    KdcNames: kdc1.cbs.dk kdc2.cbs.dk

Adding "HTTP/od.cbs.dk@CBS.DK" to my CBS.DK and using mod_auth_kerb inApache. SSO worked on both Windows and Linux clients with HHK.DK tokens.
In my log file "/var/log/krb5kdc.log" I could see that a lot of requestcame from windows machines.

Now the IT department created a UPN suffix on the AD called CBS.DK andSSO stopped working on Windows clients. The request in"/var/log/krb5kdc.log" stopped.
We removing the UPN suffix from the AD, but Windows clients is notworking and the request to "/var/log/krb5kdc.log" do not happen anymore.Everything is fine on Linux.
It seems that Windows clients no longer uses the "HKLM\SYSTEM\CurrentControlSet\Control\Lsa\Kerberos\Domains\CBS.DK" in the reg.
Have been searching the net for month now. Anyone has any ideas what iswrong ?
Is there a way to map domain to realms in Windows like [domain_realm] inkrb5.conf ?

Med Venlig Hilsen / Kind Regards
