Vcenter 5.1 problem with SSO

Hi,

I just installed a new 2008 R2 Windows with 2008 R2 SQL.

i installed the vcenter with the <first> option (easy install).

All went well.

When I try to connect with the vmware client, it says I don't have permissions.

When I try to connect with the Web Client, it says: Could not connect to one or more vCenter Server systems:https://server.domain:443/sdk

any ideas?
