This article applies to:
- Trustwave MailMarshal (SEG) 8.X and below
- Active Directory
Symptoms:
- Attempting to add a group to the security permission on the Console Security or Manager Security tabs of MailMarshal Manager Properties or Server Properties
- Used the browse button to add the group, and the group is in the same domain.
- Error message: Failed to convert user: Unable to get Sid - The trust relationship between this workstation and the primary domain failed.
Causes:
The Console Security and Manager Security use the pre-Windows 2000 name to add the group to the security section. If the Group name and pre-Windows 2000 name do not match, this error results.
Resolution:
To correct the problem, edit the properties of the Active Directory group using AD management tools.
- In the General tab of group properties, update the Group name (pre-Windows 2000) and ensure this name exactly matches the name of the group.
- The image below highlights the field to change. This entry must match the group name shown above the line.
