I'm trying to install Storage Manager for Active Directory but got the following problem.

When trying to login to the NSMAdmin client I get the following error:
"Authentication failed due to logon rights not being granted to the account".
The user I'm using is a member of domain admins.

I read in the installation guide that the login user must be a member of the group "NSMAdmins" but I can't find this group anywhere in the AD. Is it supposed to be created during the Engine installation?
The NSM Engine was installed without any errors and is running without any errors received.

I'm running this on a DC with Windows 2008 R2 Standard 64-bit. Storage Manager v3.0.1.
