Error NoPermission when access to vCenter is provided via group

Hi All,

I have installed new vCenter server 5.1.0, 1123961 on server 2012 OS (server is joined to AD).

If we give access to user directly they can logon to vCenter via vSphere / Webclient with out issues.

If we give access to AD group and make user member of the group, admin users are getting error NoPermission.

We have give administrator permission to group on vCenter server, Not sure what is the cause of the issue.

Log from vCenter server.
