Questions: 

We have LAN that has a cluster of VAXs (6000s on CI,4000s on DSSI)
and also some standalone Alphas (1000s,2100s and a 2 node 4000 cluster)
All of these systems run the same application. Disaster Recovery is proving
to be a problem since we have to have the same number of
systems at the D/R site because the application allows Users
to create their own Usernames. Hence it is not possible to
concatenate these systems down on to say one large VAX and
one large Alpha because there are Username duplications.
Is it possible to make the SYSUAF,RIGHTSLIST etc files network
wide so that their is only one. Currently each cluster or stand-alone
system has it's own which causes the problems of duplications when
we merge them. Thanx in advance.

1565.1VMScluster Supports 150 Miles, Given BandwidthXDELTA::HOFFMANSteve, OpenVMS EngineeringTue Feb 11 1997 17:0113
   It is possible to operate a single VMScluster over relatively long
   distances -- the current supported limit is 150 miles.  One can use
   a standard VMScluster, or one can use the features added to the
   standard VMScluster in the BRS VMScluster services package.

   If one cannot share the authorization files via a VMScluster, the
   procedures (either in DCL, programs, or administrative steps)
   must be put in place to synchronize account creation.

   External Authentication is supported for use with LANMANAGER, but
   an OpenVMS-to-OpenVMS authenticator is not currently available from
   Digital.  Third-party packages may be available.
