[OpenAFS] what is the state of the art client setup for openafs + krb5 + windows

We run recent 1.7 clients on our Windows 7 64-bit and Server 2008R2 
computers along with MIT KFW 3.2.2, and we use the integrated login.

Our setup is perhaps a little different than most, but we use alternate 
security identities at our site.  For a user "username":

     cs.wisc.edu                AFS cell name
     username@CS.WISC.EDU    kerberos principal
     username@AD.CS.WISC.EDU    Windows domain user

All passwords for users are in the kerberos domain, and a kerberos trust 
between the MIT KDC and domain controllers is in place.  The Windows 
user has an "altSecurityIdentities" entry set pointed at 

This setup will fetch a kerberos ticket from the MIT KDC at login, and 
that ticket is used to get an AFS token during login with integrated 
login enabled.  It has worked quite well for our site.

Documentation from Microsoft for how to set this up was originally 
written for Windows 2000 (?!), but it still seems to work fine with 
modern Windows.

encryption types need to be enabled in group policy to allow DES 
principals to authenticate and obtain an AFS token.
