How To (correctly) reference an LDAP entry

Hello,

I have some entries in my own OpenLDAP server (Server A, Base: dc=tu-clausthal,dc=de) and would like to link each of them to entries stored on a foreign LDAP Server (Server B, Base: ou=X,o=Y,c=Z).

I have added the "seeAlso"-attribute containing the DNs I want to link my LDAP-entries to, but since they are in another name space and on a foreign Server, they point to "nil".

Do I have to rebuild the foreign namespace to just add a reference to the other server? How would I do that most cleverly on OpenLDAP?

Or is there another way to create (correct) external references?

Am I even using the "seeAlso" attribute correctly?

bye Christian
