Current configuration -
1 Cisco ASA with 3 interfaces configured, 1 - Internet, 1 - LAN, and 1 - DMZ
1 Edge Transport server connected to the DMZ
2 CAS/HT in a CAS Array with MS NLB connected to  the LAN
2 Mailbox servers connected to the LAN with failover clustering

I have created an Edge Subscription and the Test-EdgeSynchronization all worked and mail passes from the Internet through the Edge server and to the HTs, and of course then to the Mailbox servers. My problem is that when I install TMG, the EdgeSync fails, unable to connect to LDAP server. So it's for sure something with TMG. I had it set up with a single NIC and am seeing some postings out there that this might not be the best design. Is it possible that's why this isn't working? Any suggestions or help in a step-by-step configuration for this would be great. I haven't seen anything that is exactly how my setup is and have tried all and still not working.
