ThorstenT,
I was curious as to how you got the vSphere Web Client SSL certs replaced? We have replaced the vCenter certs and that works fine, not warning messages about certs when hitting the URL or using the vSphere client. I took those same certs and put them in the
C:\Program Files\VMware\Infrastructure\vSphere Web Client\DMServer\config\ssl folder and restarted the vSphere Web Client. When putting the URL in the browser, it comes up fine and no cert errors. IE shows the padalock and I can confirm that it is using the right cert. However, when I enter my credentials to log in, it pops up the box about the cert being untrusted. The thumbprint is right so I know it is using the correct cert issued from our CA, but the vSphere Web Client still sees it as untrusted for some reason. As I said, the same cert works fine with vCenter and Update Manager and the login page for the Web Client seems happy with it as well, it's just after the authentication. I also see the same issue when registering it via the admin-cmd.bat file (no Flash on the server to use the browser).
Thanks,
Bob
