Background Information
When you change Project Server’s method of
authentication from Mixed to Windows Authentication only, the system blocks
every account that uses Project Server authentication and prevents those
accounts from accessing Project Server entirely. This action blocks you from
using the built-in Administrator account because it uses Project Server
authentication.
Because of the risk associated with changing the
method of user authentication in Project Server, we strongly recommend that you
add several Windows-authenticated user accounts to the Administrators group so
that someone can log into Project Server and perform administrator capabilities.
If you fail to do so before changing the method of authentication, you will
prevent yourself from being able to administer Project Server.
Resolution
To reset Mixed authentication as Project Server’s
method of authentication, complete the following steps:
1. Launch the SQL
Server Enterprise Manager
2. Select and
expand the Project Server database
3. Locate and
return all rows for the MSP_WEB_ADMIN table
4. In the
MSP_WEB_ADMIN table, change the WADMIN_AUTHENTICATION_TYPE value to 3
