Hi
I could succefully uninstall the SSO and everything else (keeping the database) and reinstall. I did however have to add the datasource manually since the vCenter installtion removed that.
Also, the problem with the "Unable to connect to one or more vCenter server systemes when logging in to the web client" error was not only the missing pointer, but the name i had on my vCenter server. I had _ (underscore) in the name. When i renamed the server before reinstalling, the Web Client found the vCenter server without any problem.
So, lessons learned. You can uninstall vCenter safely, as long as you keep the database. (backup recommended anyway).
And,
dont have underscore in the server name. =)
