[krbdev.mit.edu #6717] Bug in MIT Kerberos for Windows Version 3.2.2 - Win7 x64

[Justin Brinegar via RT]

Hello,

I am unable to obtain a TGT for the configured default realm when 
logging on to a 64 bit Windows 7 machine.  Following the same 
configuration steps detailed below on a 32 bit Windows 7 machine, I am 
able to obtain the TGT as expected.

To reproduce the issue:
1) Install KFW 3.2.2 MSI (32 bit)
2) Install KFW 3.2.2 MSI (64 bit) - note that this requests to remove 
the above.
     - The MIT Kerberos page on secure-endpoints.com suggests "(on 
64-bit Windows install both the 32-bit and 64-bit MSI packages)"
     - Even if the order is reversed, the symptom persists.
3) Replace krb5.ini with a fully configured copy, default realm is 
ISIS.UNC.EDU
4) Create local account, add to admin group - match password with 
Kerberos password.
5) Log out, log in as local account and configured the 
brinegar at ISIS.UNC.EDU.
6) Log out, log in again as local account - no TGT.

If the steps are followed on a 32 bit machine, I get a TGT from 
ISIS.UNC.EDU.  Why can't I get one when this setup is performed on x64 
Windows 7?

The symptom persists if UAC is off.  I originally suspected a policy on 
the Windows Domain I was using was causing the problem, but I have ruled 
that out.

Please let me know what logs (please send instructions for obtaining 
such logs) or other information I should send.

Justin
