How to add default attribute in Sun One directory server !!!

Hi,

I am new to LDAP and Sun one directory server.

We have to add one attribute as a default attribute in the Sun one directory server.

Currently we are having entry called User which has firstname,lastname and UID.

Now we want to add globaluserid attribute also in the user node and it should be default.

i.e from webapplication when we create new user it should also enter global iser id in the direcroty server.

Thnx in advance.
