vSphare Data Protection option not shown in vSphere Web Client

Hi,

I have just upgraded vCenter virtual appliance from version 5.0 to 5.1.0.5100-799730. Then I have installed vSphereDataProtection-5.1.56.179. Deployment and setup finished with no errors. When I log in to VDP website, all services are "green" and running.

When I log in vSphere Web Client, I cannot see Data Protection as an item in menu...

I have tried to register VDP in vCenter once more (have changed name to IP in VDP configuration - vCenter registration). After VDP restart I was watching all messages shown on console, and VDP has registered in vCenter.

I have tried to restart VDP, vCenter, to log in and out from vSphere Web Client, no success.

What can be wrong?

Thanks,

Marcel
