IF you log into Windows using an AD account AND you have OpenAFS
Integrated Logon turned on AND there is an afs/cellname@DOMAIN key in AD
THEN you will obtain a token for "cellname" upon login to Windows.

Yes.   They must have different kvno values.

As long as the keys are distinguished by kvno you can use it.
In this case your cellname must be the same as one of the realms (except
lower case) and the name of the other realm must be placed into the AFS
krb.conf file.

Doing so means that user@REALM and user@DOMAIN are both treated as
"user" by AFS.   Therefore, you must ensure that there are never any
conflicts.   It also means that both the REALM and DOMAIN had better be
administered by the same entity.
