Users can't connect to PWA from their client computers. When I try to access PWA with the same users from the Project Server 2010 Server (the phisical server which host PS 2010 and SP 2010) on IE, it works great. Even if I create a new "Admins" group with Full Access and populate it with the user accounts, they still can't connect to PWA from their computers...
For the Farmadmin account it works fine from every hosts (Server and clients).
Users receive "Access denied, Sign in as a different user" error message from their client computers or even from the SBS 2011 DC server. When I try to log in PWA with the same AD users directly on the Project SharePoint server it works just great...
When they ping the Project SharePoint server name which is used in the URL they resolve the correct IP.
I think that I don't use Kerberos in this SharePoint Farm.
Any idea ?
Thank you for your help, best regards,
