Setting Up the Extension and Authorization DLLs

At startup, IAS checks the registry for a list of third-party DLLs to call.

To set up an Extension or Authorization DLL on an IAS server, list the paths to the DLLs in values below the following registry key:

HKLM\System\CurrentControlSet\Services\AuthSrv\Parameters\

If the AuthSrv and Parameters keys do not exist, create them.

The value in which to list the Extension DLLs is:

ExtensionDLLs

The value in which to list the Authorization DLLs is:

AuthorizationDLLs

Both the ExtensionDLLs and AuthorizationDLLs values must be of type REG_MULTI_SZ. This type allows you to list multiple DLLs.
