Separate from your DES issues, there are two serious problems here.

1. You are creating an account with a logon name of "afs/pitt.edu"
instead of something like "afs-pitt-edu-cell" and then setting a Service
Principal Name of "afs/pitt.edu@PITT.EDU" on that account.

The slash in Kerberos is a name component separator.  When aklog
requests a ticket for "afs/pitt.edu@PITT.EDU" it is asking the PITT.EDU
KDC for the principal

  "afs" "pitt.edu"

Not the principal

  "afs/pitt.edu"

2. You cannot give the account the name "AFS" or have a short name of
"AFS".  Doing so will cause name resolution of "afs@PITT.EDU" to succeed
which will in turn break all of your deployed Windows AFS clients.
