OpenVMS Distributed Authentication? (Passwords)

» close window

The Question is:

 
I have a multi-node multi-cluster environment.  We have both VAX and Alpha
 nodes.  There are many users who have accounts on multiple clusters.  This
 currently requires them to have seperate passwords for each account on each
 cluster.  I am wondering if t
here is a way to
1.  Have a single sign-on point that will then
    point them to the correct node.
 
2.  When a user changes a password for one
    account it changes the password for the
    other accounts for the same user on
    different clusters.
 
Thanks
Dave

The Answer is :

 
  The only approach currently available for single sign-on is via
  Advanced Server, LAN Manager, and External Authentication.
 
  V7.3 (currently in field test) provides access to Kerberos-based
  single sign-on capabilities, and an OpenVMS-based Kerberos client
  and Kerberos server.
 
  Additional work in this area is presently underway, including
  the implementation of a generic API permitting OpenVMS to be
  connected to site-specific external authentication (hardware or
  software) mechanisms.
