Hi Sebastian, Thanks for your reply. We've created the CA and Server certificates on Red Hat Directory Server (like described in: http://www.redhat.com/docs/manuals/dir-server/ag/8.0/Managing_SSL-Using_ certutil.html <http://www.redhat.com/docs/manuals/dir-server/ag/8.0/Managing_SSL-Using _certutil.html> ) And created a server certificate on the Windows Server (http://support.microsoft.com/kb/931351 <http://support.microsoft.com/kb/931351> ) The CA and Server certificates are exchanged between the both Servers and are trusted, like the certutil output shows: On the Red Hat Directory (rhds.grep): # certutil -L -d . Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI rhds_ds_ca_cert CTu,u,u parijs_server_cert ,, rhds_server_cert u,u,u parijs_ca_cert CT,, on the Windows Active Directory (parijs.gem): C:\Program Files\Red Hat Directory Password Synchronization>certutil -L -d . rhds_ds_ca_cert CT,C,C rhds_ds_server_cert Pu,Pu,Pu And the ldapsearch in the command line from the Red Hat server over SSL works with the use of the certificate database, the following command returns entries of Windows Active Directory: /usr/lib64/mozldap/ldapsearch -Z -P /etc/dirsrv/slapd-rhds/cert8.db -h adsync.parijs.gem -p 636 -D "CN=Administrator,CN=Users,DC=parijs,DC=gem" -w - -s base -b "dc=parijs,dc=gem" "objectclass=top" Note that I'm using a Red Hat Enterprise 64 bits version and a Windows 2003 32bits. Do you've got any suggestions why there are no outgoing tcp/ip packages from the Red hat Directory Server when the new Windows Sync Agreement is configured and the message is shown that the Red Hat server is unable to contact Active Directory server?

Subject: Re: Unable to SSL with Windows Sync Agreement Mathisj, If I'm not mistaking, in order for the two servers to be able to talk with each other, they need to have certificates signed by Certificate Authorities recognized by the two servers (meaning, the certificates of these root CAs must be installed on the two servers). Even more straightforward is to generate certificate requests for both servers and get them signed by the same root CA. --- On Thu, 7/31/08, Groot, Mathijs de (IDT Competence Java) <math.de.groot at logica.com> wrote: From: Groot, Mathijs de (IDT Competence Java) <math.de.groot at logica.com> Subject: Unable to SSL with Windows Sync Agreement To: fedora-directory-users at redhat.com Date: Thursday, July 31, 2008, 12:18 PM Hello everyone, I can use some help with setting up the Windows Sync. Ill give some context first, im trying to sync user, groups and passwords from a Windows 2003 server with Active Directory with a Red Hat enterprise 5, Red Hat Directory Server 8.0. It is a test environment with where I can access and configure the servers easily. But ive got some problems setting a new Windows Sync Agreement. It comes down to the following: I can't get an SSL connection with the a new Windows Sync Agreement, from the Red Hat DS to the Windows AD server. In the Windows Sync Server info screen I get the following message when clicking on next: "unable to contact Active Directory server, continue" (Windows Sync Server info screen located In the Directory Server Console -> Configuration tab -> Replication -> userRoot -> highlight the database -> Object -> New Windows Sync Agreement -> The second screen reads Windows Sync Server Info) But when I uncheck the checkbox "Using encrypted SSL connection" the connection works and the Windows AD server is reached. So this concludes (and ive tested) that the Windows Server and domain is reachable and the Bind DN is valid, and entered values are correct. The SSL connection seems to be setup correctly, the checks (ldapsearch query) described by the fedora manual outputs the correct result. Following: " http://directory.fedoraproject.org/wiki/Howto:WindowsSync <http://directory.fedoraproject.org/wiki/Howto:WindowsSync> Testing your Configuration Test to make sure you can talk SSL from Fedora Directory to AD This is how you test to verify that the Windows side SSL is enabled properly: ldapsearch -Z -P <RHDS-cert8.db> -h <AD/NT Hostname> -p <AD SSL port> -D "<sync manager user>" -w < sync manager password> -s <scope> -b "<AD base>" "<filter>" " My ldapsearch query: /usr/lib64/mozldap/dapsearch -Z -P /etc/dirsrv/slapd-<instance>/cert8.db -h compute.domain.com -p 636 -D "CN=Administrator,CN=Users,DC=domain,DC=com" -w <pwd> -s base -b "dc=domain,dc=com" "objectclass=top" But strangely enough there is not network traffic at all when the SSL connection is checked! (when clicking on next and the message "unable to contact Active Directory server, continue" appears) Ive done the following actions to make to monitor it: First I've disabled SELinux, in case that blocks something (just for testing). watch the tcp ip traffic with: tcpdump -nn -p port not ssh and ip host <Red Hat IP number> Here I can see that, when I don't use the SSL connection, there is traffic towards my Widows AD, but when ive check the SSL option, there is no traffic at all, nothing. As well when I look at the iptables: added an extra line: iptables -I OUTPUT 1 -d <Windows AD IP number> -j ACCEPT watch -d iptables -L -nv I see the same result, traffic when I don't use the SSL option and no traffic at all when the SSL option is checked. How can I get the message "unable to contact Active Directory server, continue" when there is no outgoing request from my Red Hat server. Ive made certificates at both sides (Windows and Red Hat) and exported and imported these certificated to the other server. Please advice on following steps I can take, what the problem can be and how it is possible that there is no traffic at all. Thanks in advanced.
