Please verify the Project Server connection info you configured in the Allocatus Server Configuration (Allocatus Server Configuration/Connections/Project Server) and review the Admin Guide (http://community.allocatus.com/files/folders/allocatus/entry15.aspx). Please use following guidance for troubleshooting:
Project Server 2002/2003
Login failed for user
In conjunction with Project Server 2002/3 you need to created a SQL Server account with read/write permission on the ProjectServer database. Please see Admin Guide for details (http://community.allocatus.com/files/folders/allocatus/entry15.aspx). We strongly recommend using the Express Setup mode, because it does this automatically.
