David:

The OpenAFS Integrated Logon Network Provider obtains Kerberos 5
service tickets and sets AFS tokens for the user session when KFW
is installed.  (see the release notes.)  You would have to explain
further what you mean by deadlocking with XXXX in order for anyone
to be able to help you.  This explanation should include debugging
log output for the network provider demonstrating how the network
provider is failing.

In addition, KFW's ticket managers support the importation of
credentials from the MSLSA and the automatic acquisition of AFS
tokens from arbitrary numbers of cells with or without cross-realm.
You should experiment with OpenAFS 1.5.11 and KFW 3.1.

If you don't want to rely on cross realm for this, you can add
an afs/asu.edu@AD.ASU.EDU (fix your domain and cell names) principal
to AD that is configured to "Use DES only", product a keytab for it
with KTPASS, and import the key into the AFS cell's KeyFile with
asetkey.   You can support keys from different realm/domains in the
same KeyFile provided that they have different kvno values.
I suspect you already have both realm names in your AFS krb.conf file.
