Hello, First of all, I would like to tell you all that that this is my very first message to this mailing list so please be patient with me for a while and sorry for the possibly dull questions. Also, it's important to let you guys know that I already learnt a lot only by searching the list archives. Thanks :-) I tried each and every bit I found online (be it by reading the enormous amount of documentation under http://directory.fedoraproject.org/ or by reading the mailing list archives) and couldn't get Windows Sync using SSL to work yet. What I have now : 1) Fedora Directory Server 1.0.4 running under a REd Hat Enterprise Linux 4 Advanced Server Update 5, installed from the fedora-ds-1.0.4-1.RHEL4.i386.opt.rpm package. This host is named fds.aw2.local. 2) Windows Server 2003 Enterprise Edition running a locally Active Directory set up only for testing. This host is named adserver.aw2.local. I already installed PassSync (from http://directory.fedoraproject.org/download/PassSync-20060330.msi) in the Windows Server 2003 and already have it configured to use the following information : Host name : fds.aw2.local Port number : 636 User name : uid=replication, cn=config Password : 123456 Cert Token : 123456 Search base : dc=aw2, dc=local uid=replication is a user I added to FDS, under cn=config. Cert token is the correct certificate token and search base is the correct search base as well. I can create a Windows Sync Agreement and have it doing synchronization both from AD to FDS and from FDS to AD, but only when using a non-SSL connection. But, in this case, as you all know, I don't get users passwords sychronized. I thin I got both AD and FDS SSL setup right as I can use "Active Directory Administration Tool (ldp.exe)" to connect to AD on port 636 (SSL) correctly and I can use an ldapsearch from the FDS machine to the FDS directory using SSL correctly as well. The only problem I'm getting is whenever I try to set up a Windows Sync Agreement using SSL I get the following error message on my FDS LDAP error log (/opt/fedora-ds/slapd-fds/logs/error, in my case) : [18/May/2007:08:52:40 -0300] NSMMReplicationPlugin - agmt="cn=sync" (adserver:636): Simple bind failed, LDAP sdk error 81 (Can't contact LDAP server), Netscape Portable Runtime error -8179 (Peer's Certificate issuer is not recognized.) I have the following configured regarding certificates in the AD host ("certutil.exe -d . -L" output running from C:\Program Files\Red Hat Directory Password Synchronization\) : CA certificate CT,C,C Server-Cert Pu,Pu,Pu Isn't this certificate database the one which is being used when a Windows Sync Agreement is set up ? Anyway, I already also tried the following : 1) Import the FDS certificate using : cd /opt/fedora-ds/alias /opt/fedora-ds/shared/bin/pk12util -d . -P slapd-fds- -o servercert.pfx -n Server-Cert 2) Import it into AD certificate snap-in in Windows Microsoft Management Console and reboot. No luck with this also. I have read and re-read every single bit of documentation I could find about the topic and I have no problem reading more if you guys ask me to RTFM. Just point me to the "fine" manual :-) Regards, -- Andr? Lu?s Lopes andrelop at aw2net.com.br
