So let me describe the setup: I have a server (RHEL 5.1) running Fedora Directory Server and Fedora Admin Server. It used to be Fedora-DS 1.0.4 (installed from rpm). A few days ago, I upgraded Fedora-DS to 1.1. For the upgrade procedure, I followed the instructions on the website regarding prerequisites and repo configuration. Afterwards, I ran the migration script migrate-ds-admin.pl. It stated that migration was done successfully (as per the logfile in /tmp/), only failed to start the admin server. Which I then did manually. The directory server was started automatically. Now I would like to use my workstation (running Fedora 7) for configuration. Java is JDK 1.5.0_14 from Sun. In the past, it worked after installing Fedora-DS 1.0.4 rpm and starting the console by ./startconsole. After the upgrade, I tried to duplicate the earlier approach and upgraded everything Fedora-DS-related on my workstation to version 1.1... Then I tried to start the console via fedora-idm-console. It didn't work 100%: I was able to open the configuration window for Fedora Administration Server from the main console window. However, I was unable to open the Fedora Directory Server configuration window from the main console. There were always error messages about a missing/incomplete fedora-ds-1.0.jar and clicking button "Download" in the main console didn't chnage anything. In order to see whether it might be a Java-related problem, I used a virtual machine with Windows 2000, fedora IDM console (.msi) and Sun-JRE 1.5.0_15 for crosschecking. Same failure in the main console window when trying to access the Fedora Directory Server (the one on the RHEL server) configuration window . Then I changed the JRE to Sun-JRE 1.6.0_06. Still, the same error when trying to access the Fedora Directory Server configuration window. So I removed everything Fedora-DS-related on my workstation, including ~/.fedora-idm-console. Next step was to install package fedora-idm-console only through yum. Afterwards, I started the console on my workstation by fedora-idm-console -D 9 -f fds_console.log From studying fds_console.log, I learned that the console apparently could not find fedora-ds-1.0.jar and fedora-ds-1.0_en.jar on the server (error 404). Fedora-ds-1.1(...).jar were found. So I went over the file structure at the server and found the fedora-ds-1.1(...).jar files in directory /usr/share/dirsrv/html/java/. However, copying fedora-ds-1.0.jar and fedora-ds-1.0_en.jar to /usr/share/dirsrv/html/java/ brought no change, fds_console.log still showed the error 404. Only after manually creating (sub)directory /usr/share/dirsrv/html/java/jars/ and copying fedora-ds-1.0.jar + fedora-ds-1.0_en.jar in there (only those two), the error 404 disappeared from fds_console.log. The current status is: On my (Fedora 7) workstation, I can open Fedora IDM console. Problems begin once I expand (in the main console window) the subtree below "Server Group". I still can access Fedora Administration Server and open its configuration window. The (workstation/console) logfile fds_console.log shows that fedora-admin-1.1.jar gets downloaded from server to workstation. When attempting to open entry Fedora Directory Server, the console downloads fedora-ds-1.0.jar and fedora-ds-1.0_en.jar. But I can't open the corresponding configuration window from the console. Fds_console.log shows plenty of "class not found messages" and ends up in a Java exception error (attached below). At least as far as I am aware, there should be no more Fedora-DS components at level 1.0.4, neither on the server nor on the workstation/console side. However, while writing this down, I just double checked with JXplorer and found in cn=Fedora Direcory Server, ... , o=NetscapeRoot the attribute nsProductVersion as 1.0.4. Is this maybe the reason for all my troubles? Is there a way to find out whether my directory server is really still left at version 1.0.4? As mentioned above, based on the feedback of the migration script, I was honestly convinced it was successfully migrated. If is just a matter of an inaccurate version string, I could easily correct that through JXplorer. But to what value? I regret to cause that much trouble. Nevertheless, I appreciate your ongoing and fast advice.
