Server error returned by ZSS in Client Certificate authentication is translated to 401

[pablocarle]

Describe the bug
If ZSS returns 500 when validating user identity mapping in X.509 authentication, the client will receive a 401. It's not wrong but it can make more difficult the analysis by assuming there's a misconfiguration in the certificate or the mapping for example.

Expected behavior
Should it maintain the 500 Internal Server Error? It would be clearer from the beginning that there's some anomaly happening in the server side rather than a misconfiguration.
