I am running iFolder 3.7 on a SLES 10 SP2 server using MS 2003 Active Directory as my LDAP server. The iFolder server is in the DMZ and the AD server is internal. I have SSL setup between AD and iFolder successfully. The iFolder web interface works fine.

Here is the problem:

The iFolder client will not connect to the server after the initial iFolder has been setup. Any new folders get a "Server unavailable" message even though the initial iFolder that was created at setup works fine. I ran a tcpdump and see that the inital folder connects to the server via https, but subsequent folders connect http. Are there particular ports on the firewall that need to be opened besides 80, 443, and 636?

Thanks for the help,
