IFS Database Error
If you are unable to log into Infor Federation Services (IFS) with a very vague error message, check the event viewer on the AD FS server to see if there are any more descriptive messages there. A database login issue could indicate that the install user for IFS doesn’t have the proper permissions on the database. Make sure the Lawson and spinstall accounts both have full access on the two databases that are created by the IFS install.
