To summarize: Directory server and admin server were upgraded (migrated) from version 1.0.4 to 1.1. Migration was handled by provided script migrate-ds-admin.pl. After migration, fedora-idm-console from remote workstation was able to open admin server, but not directory server. This setup worked when servers and remote console were still at version 1.0.4. Cause: It was found that during migration several entries in subtree below "o=NetscapeRoot" (section "cn=Fedora Directory Server") were still pointing to the old file fedora-ds-1.0.jar. Actually, all references in cn=Fedora Directory Server were still pointing to the old jar file. There were other (textual) references to previous version no. 1.0.4 as well. Altogether, this prevented access from local (on the server itself) as well as remote console to the Fedora Directory Server configuration window. The console tried to load fedora-ds-1.0.jar from the server which was (of course) not available. Remedy: Used a third-party tool (www.jxplorer.org) to manually change all references in the aforementioned tree part from fedora-ds-1.0.jar into fedora-ds-1.1.jar. Achknowledgements: A big Thank You goes to Nathan, Rich and solarflow99 who guided me after a week of fruitless fumbling within two days to the solution. Regards, Wolf
