Hello to all. I recently installed FDS on a CentOS 3 box. My network authenticates to a win2k3 AD box. I'd like to use the Winsync feature of FDS to keep it automatically updated. Firstly, FDS does work, to the extent that I populated ou=People, and can see and use those entries in Kmail. I've followed the Admin manual regarding installation and configuration of Winsync on both the FDS and AD boxes, but I can't get it to work. I receive an error "81- LDAP error: can't contact LDAP server". By now, it's entirely probable that I've munged up the configuration, having tried so many tweaks. I'm really not sure where to begin in terms of providing info to you so that you can help me out. With your kind indulgence, it might be better for you to ask me questions about my setup, and we can go from there (I realize that's a bassackwards way to ask for help, but ...). Here, at least, are some basics: I obtained server and CA certs from CACert.org, and plugged those into FDS. I created the user Admin on both the FDS and ADS boxes. I created a Replica Agreement. I ran the Winsync utility on the ADS box. I'm trying to use port 636. I do have a couple of questions: what's the proper way to specify a Supplier DN, and should I use "SSL client authentication" or simple authentication" in the Replica Agreement? Many thanks. Dimitri
