You need to make the change on the Active Directory account.
You must set the "use DES only" flag and then set a new password.
You can then export the key so that it can be set within AFS
using asetkey.

You must be using a version of OpenAFS 1.3.xxx or the 1.3 Release
Candidate as Active Directory wants to use DES-CBC-MD5 and that enctype
is not understood by the 1.2 series servers.
