[horde] Hook Question

[AJ]

I have the fullname and from address hooks working for horde, however I 
have a question.  I am using LDAP to get the information, and under my 
Users OU, I have other OU's also containing user accounts.  So, here is 
how it is set up:

Some user accounts here:
ou=Users,dc=mindcrash,dc=com

Other user accounts here:
ou=Other,ou=Users,dc=mindcrash,dc=com

The hook works for the first example, and retrieves the info for 
fullname and from address, but it does not for the second example.  It 
seems that if there are other OU's it does not search down.  I am using 
the hook examples from the wiki page.

Any idea how to get it to search down through the ou?

Thanks.
