I recently had a customer run into an interesting error when integrating a SafeNet Luna SA5 Network-based HSM with their ADRMS infrastructure. 

Problem


When the customer attempted to protect content, he received an error "A problem occurred when contacting the restricted permission service".



We verified that the customer could reach the Certification and Licensing sites without an issue.

To further isolate the problem, we followed the steps to set up Server and Client-side tracing.  On the server, we saw the error below in DebugView when we attempted to rights-protect content.

[DirectResult] Error (Id=0) System.Runtime.InteropServices.COMException (0x800706D9): There are no more endpoints available from the endpoint mapper. (Exception from HRESULT: 0x800706D9)            

At the same time, the IIS logs showed HTTP 500 errors when attempting to license content.

The Application event log on the ADRMS server had the following events:

Log Name: Application

System.Security.Cryptography.CryptographicException
Message: Provider DLL failed to initialize correctly.

Context: ComponentBase.LogResults

To determine if this was specific to the HSM or some larger issue, we re-installed ADRMS with the exact same setup without using the HSM.  The user was then able to protect and consume content without a problem.  After re-installing with the HSM in place, the error returned.  Also, when attempting to rights protect content with the HSM, the user was prompted to provide either Windows Live ID credentials or use domain credentials.  When the user chose domain credentials it threw the error.  Without the HSM in place, the user was not prompted for credentials.

Resolution

When working with the customer's on-site HSM technician, he noted that they were using strongprotect on the communication channel between the Luna HSM client on the ADRMS server and the Luna HSM.  He noted that this had caused problems in the past with a Microsoft Certificate Authority.  We recreated the channel by following the steps below:

Open an Administrative Command Prompt
cd "C:\Program Files\LunaSA\CSP"
Register /partition /highavail
IISReset


After performing these steps, the user was able to rights-protect and consume content from Microsoft Word.  After we completed this, we ran Register /strongprotect and we were still able to protect content.
