When providing access to a SQL server for the Active Roles service account via a Windows security group, the following error is observed when attempting to start the Active Roles Administration Service:
Insufficient rights to access the Active Roles database. Ensure that your login has the default schema of "dbo" in the Active Roles database.
If you use Windows (integrated) authentication to connect to SQL Server when installing the Administration Service, ensure that the Windows user account under which you run Configuration Center has a login on SQL Server mapped to a database user with sufficient permissions to perform Administration Service installation tasks. For a list of permissions, see “SQL Server permission/Configuration permissions” in the Active Roles Quick Start Guide.
Waiting for fix in a future release of Active Roles.
