Configure the appropriate assembly and class
Make sure that the appropriate assembly and class are configured. When you point to a custom transform module dynamic-link library (DLL) file, make sure that the Class name that is specified on this tab exists in that DLL file.
To perform this procedure, you must be a member of the local Administrators group, or you must have been delegated the appropriate authority.
To specify the file path for the transform module settings in the trust policy:
- On the federation server, click Start, point to Administrative Tools, and then click Active Directory Federation Services.
- In the console tree, under Federation Service, right-click Trust Policy, and then click Properties.
- Click the Transform Module tab, and then type the file path in DLL file.
For further troubleshooting, contact the module vendor.
