Question : LDAP query in a two way trust relationship

Hello,
I set up an external trust relationship between to forests; CompanyA and CompanyB. I have an LDAP Server linked to CompanyA for authentification. I want to authenticate the users from both companies using the LDAP server.
When i do an ldap query for a user in CompanyA from the LDAP server it responds fine.
BUT when i query for a user in CompanyB for user1 (trust relationship) the query times out or does not respond.

LDAP -> CompanyA -> CompanB ->user1
I need to get to usre1 from the LDAP.
Is there a way to replicate an OU from CompanyB to CompanyA?
Thank you

Not easily and you won't trivially get passwords.

LDAP Authentication systems are normally limited to a single domain, a single LDAP connection, if you're trying to use LDAP authentication via Domain1 for a user in Domain2 it will fail. Is that what you're trying to get to work?
