Single SignOn Installation 

This page explains how to set up Single SignOn so that users enter their LAN
Manager passwords to log on to OpenVMS. 

Pre-Requisites 

You are going to need the following: 

   OpenVMS V7.1 installed and running. FT1 (BL5) or later is required
   (this is X67V or later on Alpha and X6FL or later on VAX). 
   MOTIF V1.2-4 (for support of the new /LOCAL qualifier, V1.2-3 will
   work just fine in all other respects). 
   PATHWORKS 5.0d. Installed, configured (can be primary domain
   controller, backup (secondary) domain controller, or member), and
   running in a LAN Manager domain. 
   PATHWORKS authentication module. This will ship on the
   PATHWORKS kit. For now you copy a field test version; select either 
   vax or alpha. 

What To Do 

Here's what you need to do to get External Authentication running on your
system. 

   Rename the PATHWORKS authentication module that you copied so
   its named PWV5_ACME.EXE. Place it in SYS$LIBRARY, and make
   sure it is world readable.
   Edit your system startup file and add the following commands so they
   are executed after PATHWORKS is up and running (to save yourself a
   reboot execute these three commands now as well): 


      $!+
      $! Turn on Single Signon, using PATHWORKS as the authenticator.  
      $!-
      $ define /system /exec SYS$ACME_MODULE SYS$LIBRARY:PWV5_ACME  
      $ install add /open /head /share sys$acme_module
      $ define /system /exec SYS$SINGLE_SIGNON 1


   Enable external authentication on a per-user basis. For each user: 
      Use the PATHWORKS ADMIN utility to set the
      HOSTNAME field in the user's LAN Manager domain account
      to his/her OpenVMS account name. Note that this step is only
      necessary if the user's LAN Manager userid is not the same as
      their OpenVMS username. 
      Tell OpenVMS that this user is to be externally authenticated: 


         $ mcr authorize
         UAF> MODIFY user /FLAG=EXTAUTH
         UAF> EXIT
         $

That's it. Each user with the ExtAuth flag set will now have to specify their
LAN Manager userid and password when logging in to the OpenVMS system.
