[389-users] Add attributes to user objects.

Hello, I want to associate servers to user objects in my directory using attributes that contain the server names. I want to do this so I can query the directory based on the attributes. In the end I would like to map drives based upon a attribute that contains a server name or at least gather the needed server names by searching the user.. So for example I have an existing user object.. dn: uid=test_user,dc=example,dc=com title: test account objectClass: inetOrgPerson objectClass: organizationalPerson objectClass: person objectClass: top objectClass: posixAccount objectClass: shadowaccount homeDirectory: /export/home/test_user gidNumber: 1000 uidNumber: 1000 loginShell: /bin/bash sn: user cn: test_user st: Wyoming mail: a(a)a.com givenName: test description: test user uid: test_user Now I have many users with drives on different servers based upon their geographic location. I would like to add the server names to the user object using an attribute. For example server1: mp3 server, server2:mp4server.. With the object classes I have i do not see a attribute that I can use that jumps out at me. What attribute can I use without having to extend the schema? Is there an ext_attribute like Active Directory uses? I am looking into the schema now but perhaps someone has already done this. The account would look something like below with the server1, and server2 attributes. I understand I would need to create an objectClass if I cannot find existing attributes but I hope to avoid that. There has got to be some auxiliary attributes I can use right? dn: uid=test_user,dc=example,dc=com title: test account objectClass: inetOrgPerson objectClass: organizationalPerson objectClass: person objectClass: top objectClass: posixAccount objectClass: shadowaccount homeDirectory: /export/home/test_user gidNumber: 1000 uidNumber: 1000 loginShell: /bin/bash sn: user cn: test_user st: Wyoming mail: a(a)a.comgivenName: test description: test user uid: test_user server1: mp3server server2: mp4server
