Creating multiple DN entry for single LDAP server

Hi,

Apart from the user LDAP account DN can we specify another DN with its attributes that will be created along with the user account?.
This should help many people.

something like tokens [dn:0] [dn:1] ....
[dn:0]=uid=username,dc=people,dc=site,dc=com
[dn:1]=cn=groupname,dc=groups,dc=site,dc=com

OR
my suggestion would be allowing to create entries to multiple LDAP servers solves 2 problems.

1)Different LDAP DN can be put into same LDAP server with 2 entries.
2)Same LDAP DN can be put into different LDAP server.

The UI would be ..
upon selecting a LDAP server from the list the corresponding attribute settings that is specific to this server should load up(ajax/javascript) and if any changes done to this server, those setting changes should be saved before selecting other sever in the list.

Any workaround ..?
