Hello,
after upgrade from vCenter 6.5u2 to 6.5u3, the integrated windows authentication stopped working, saying "invalid credentials" on the login screen, for both flash and html5 clients. Traditional login with username and password works fine. The enhanced plugin service is running (login screen recognizes it and the link to download the plugin is hidden, which seems ok). Cleared browser cache, reboot of server and reinstallation of enhanced plugin didn't help.
Running on Windows 2012 R2 Server (standalone, no AD), current Firefox ESR (60.9.0esr 64-bit). The same problem on both my vCenter installations. The only difference is vCenter upgrade.
Is it a known issue with any workaround?
Thanks,
David
