I beg to differ with HP's recommendation (in their doc set) for Devin'ssituation.  HP's description is meant for customer sites to have a copyof usernames/passwords to which they can revert for nasty situationssuch as a corrupted SYSUAF.DAT.  *If* this system has the 'alternate'file, it should have the same problem as the original, of unknownpasswords.  What Devin needs is instructions to break into the system.
I happen to know how to do that (used to work in OpenVMS Engineering).Is that something that should be discussed here?
Thanks,Dick
