1005.0. "referrals across countries" by VMSNET::R_HARRIS () Tue May 13 1997 17:47

    Hello,
    
    My Customer needs to have knowledge references and referrals across
    country codes. For example, he has country code of CA and a country code 
    of GB. How do we implement referrals between the two countries. The x.500 
    documentation only talks about the Country to Organizations to Org
    units. 
    
    Please advise.
    
    Thank you in advance for your support.

I dont understand the problem.

The naming contexts could be /c=ca/o=org and /c=gb/o=org,
with the main part of the data in /c=ca/o=org/ou=org1 and
/c=gb/o=org/ou=org2.

You may want the data in one org to be found if you search the
other org. In which case you need an alias entry which creates
an alias for the other org in the other one.

E.g.
	/c=ca/o=org/ou=org2 could be an alias pointing to
	/c=gb/o=org/ou=org2

	If you search /c=ca/o=org then you would also search
	/c=gb/o=org/ou=org2.

None of this involves knowledge references or referrals.

If the 2 naming contexts are stored in different dsas then you
would create subordinate references in the usual way.
I.e.
	/c=ca/o=org would be a subordinate reference in the
	dsa which stored /c=gb/o=org.

	If a dsa really holds /c=gb then you can create a
	subordinate reference at /c=gb to point to that dsa.

note that these subordinate references are a special case, as
they are not part of any real naming context.

    Re: .1
    
    Andrew,
    
    Thank you for your response. For clarity, my customer wanted me to send
    you the following message as a followup question:
    
    
Randy, thanks for the information..

I'm going to give this a shot.. However, could you pass on a clarification
to Andrew for me?

Added information to make things clearer for him.

- We are in a closed network wishing to establish directory connections
between servers between different organizations.
- My border DSA has a master naming context /c=ca
- The other border DSA has a master naming context /c=gb

If what you say is correct then all I have to do is create a subordinate
reference c=gb with access point to the other border dsa.

If I do this I should be able to call up DXIM and provided I set my initial
directory entry to "/" I should be able to browse the other directory entries.

Correct?

Regards,
Jamie

    In principle setting the subordinate reference should be sufficient.
    There might be a small problem with setting the initial directory entry
    to "/", as there is no such entry!
    
    DXIM might cope with this properly, in which case there is no problem.
    A simple experiment will show whether this is the case. Unfortunately I
    dont currently have access to a system with dxim, so I cant tell you
    whether it works or not.
    
    Note that if you master /c=gb and /c=ca then there will be difficulties
    connecting to a public X.500 service. This may not worry your customer.

    dxim does seem to be quite happy to have / as the initial entry.
