5.5 SSO issue

Hello,

I just upgraded from 5.1 to 5.5.

Now when i try to log in with an AD Account to the Web Client, I get an error "Not authenticated with Inventory Service".  When I log in with the administrator@vsphere.local account, it works fine.  I've tried removing and re-adding the AD identity source with no luck.  I've tried restarting the inventory service, no luck.

Any ideas?
