Dear all,

I´ve set up an trial installation of Skype for Business 2015. Everthing in the installation worked well, but now, when I try to logon to the "Skype for Business Server Control Panel", I will receive this errorr message

Unauthorized: Access is denied due to a role-based access control (RBAC) authorization failure.

You do not have permission to view this application using the credentials that you provided.
Contact your support team to add your account into appropriate security group (s) for Skype for Business Server administrators. Wait until the new role assignments take effect, and then try again.

I am in the CSAdministrators group and also tried different kind of users (Domain-Administrator, normal user eg.). But no one works.

Any help?

Jenny
