       XPAUsers -  Distinguishing Users


       XPA normally distinguishes between users on a given host, but it is possible to send data
       to access points belonging to other users.


       A single XPA name service typically serves all users on a given machine.  Two users can
       register the same XPA access points on the same machine without conflict, because the
       user's username is registered with each access point and, by default, programs such as
       xpaget and xpaset only process access points of the appropriate user.  For example:

         XPA xpa1 gs 838e2f67:1262 eric
         XPA xpa2 gs 838e2f67:1266 eric
         XPA xpa1 gs 838e2f67:2523 john
         XPA xpa2 gs 838e2f67:2527 john

       Here the users "eric" and "john" both have registered the access points xpa1 and xpa2.
       When either "john" or "eric" retrieves information from xpa1, they will process only the
       access point registered in their user name.

       If you want to access another user's XPA access points on a single machine, use the -u
       [user] option on xpaset, xpaget, etc. For example, if eric executes:

         xpaget -u john xpa1

       he will access John's xpa1 access point.Use "*" to access all users on a given machine:

         xpaget -u "*" xpa1

       Note that the XPA Environment Variable XPA_NSUSERS can be used to specify the default list
       of users to process:

         setenv XPA_NSUSERS "eric,john"

       will cause access points from both "eric" and "john" to be processed by default.
