RTx::EmailCompletion LDAP configuration


I’m working on adding completion against an LDAP directory in

I need to add some configuration like the ldap server, ldap filter,
ldap base, …
The LDAP authentification overlay already use RT::LdapServer, RT::LdapBase, …

I wonder if I should use the same configuration or use my own vars
like RT::EmailCompletionLdapServer.

An Idea to help me ?
