LDAP proxy issue

note: Apologize if this dupes; think i sent original out before i was approved on mailing list.

A bit stuck; bear with me; somewhat of a LDAP nubbie; sure i am missing something simple,

Trying to get a local server to AUTH locally to its own openldap-server and then proxy to corporate LDAP if user is not found locally.

1. Local users work

2. AUTH to local LDAP server works

3. AUTH to corporate LDAP does NOT work

4. LDAP search to corporate works when using local server (ack!?!)

user = corporate LDAP account

internal ldap = users - internal.com

corporate ldap = people - datacenter.corporate.com

note: anonymous bind is enabled on corporate.
