Problem with AD connection from vCenter Appliance

Hi,

Have one appliance (V5.1.0b) that I try to connect to an AD, and it says it is successful both in the GUI and if I try it from the CLI.

If I download the config-file and look at the AD-variables, they show status 1 and the right domainname.

But after a reboot, the VC_AD_DOMAIN variable is missing and the VC_AD_STATUS equals 2 (should be 0 or 1...)

Anyone that recognize this?
