Assume the following scenario:
- Users (or computers) should request certificates via the Certificate Enrollment Policy (CEP) web service.
- For this purpose, a certificate enrollment policy is configured, which points to a Certificate Enrollment Policy Web Service (CEP).
- Authentication is done via Kerberos.
- When checking the address, the connection to the CEP fails and you get the following error message:
An error occurred while obtaining certificate enrollment policy.
Url: https://cews.adcslabor.de/ADCSLaborIssuingCA1_CES_Kerberos/service.svc/CES
Error: A message containing a fault was received from the remote endpoint. 0x803d0013 (-2143485933 WS_E_ENDPOINT_FAULT_RECEIVED)
The Certificate Enrollment Web Services (Certificate Enrollment Policy Web Service, CEP, and Certificate Enrollment Web Service, CES) enable the automatic request and renewal of certificates from a certification authority via a Web-based interface. This eliminates the need to contact the certification authority directly via Remote Procedure Call (RPC). For a more detailed description, see the article "Certificate request basics via Certificate Enrollment Web Services (CEP, CES)„.
