I'm in the process of migrating to keeping all users and mail aliases in a directory server. For people-objects we use the object classes 'top', 'person' and 'mailRecipient', but I'm a bit confused as to how to store pure email aliases that are not connected to specific accounts. I think we'll want to store these in a separate ou (ou=aliases), but what's the correct set of object classes to use ? 'mailRecipient' gives me all the attributes, but isn't structural. I found the ldapSubEntry structural class that seems fitting (gives me structure, and nothing else), but from reading the deployment guide that seems to not be what we want.. (doesn't show up in normal searches). # dn: mail=test(a)example.com,ou=aliases,o=example.com,o=ISP,o=mydomain,c=NO # changetype: add # objectClass: ldapSubEntry # objectClass: top # objectClass: mailRecipient # mail: test(a)example.com # mailForwardingAddress: test(a)sometherdomain.net Any hints to what class should be used here instead of ldapSubEntry? -jf
