LDAP server

[jtrober]

I am trying to find a way to take multiple LDAP sources, pull them all into one locations, and provide one comprehensive LDAP source.

I have a NOC with hosted Email servers for many clients.

I have 6 SBS 2003 servers hosting email for 6 different organizations, as well as an IP Switch IMail server providing POP3/IMAP email hosting for many clients.

I have ONE spam filter. The spam filter allows me to provide each user with their own logon to check their spam, and unjunk if needed. I have also turn on DHA protection, only allowing emails that are user accounts on the spam filter to come through.

Problem is, this user data comes from LDAP, but it can only connect to one LDAP source at a time. This means I can not really use any of the above functionality of my spam filter because I can not pull in user data from all 7 servers like I need to.

So, what I want is some way to pull LDAP data from all 7 servers and have all that go into a database which provides one large LDAP source I can point my spam filter to.

If its something I have to buy, thats fine. If it needs its own server, I can handle that to.

Any ideas?

Can your spam filter use RADIUS?

If so then FreeRADIUS can frontend a lot of different LDAP servers.
