The HYPR Workforce Access client utilizes a Windows credential provider to perform X.509 certificate-based client authentication to log the user in to the Windows desktop without a password. Microsoft documentation refers to this as “smart card logon,” because this type of authentication is typically associated with physical cards such as CAC and PIV cards used by the federal government. In the case of HYPR Workforce Access, we have a virtual smart card.

Microsoft Certificate Services must be properly configured to ensure Workforce Access can function properly.

Issue Description

If a client experiences a situation where the HYPR Mobile App is spinning and/or timing out during a desktop authentication, it could be a misconfiguration of the Microsoft Certificate Services. Use the Windows Event Viewer (to launch the Event Viewer, just hit Start, type “Event Viewer” into the search box, and then click the result) on the client desktop to look for the following conditions:

  • Go to Windows Logs > Security and look for error The request is Not Supported and status Reported authentication failure. Status=0xC00000BB

  • The following error may be seen in Kerberos event logs on the Workstation when attempting to launch:

    0x10 - KDC_ERR_PADATA_TYPE_NOSUPP: KDC has no support for padata type
    Smart card logon is being attempted and the proper certificate cannot be located. This can happen because the wrong certification authority (CA) is being queried or the proper CA cannot be contacted.

Known Error Codes: Status=0xC00000BB or 0x10 - KDC_ERR_PADATA_TYPE_NOSUPP

Steps to Reproduce

Undo the Resolution steps below and try to log on to the desktop with WFA.


The following conditions must be met:

  • The Domain Controller certificate must be configured for smart card users; this is a setting in the Domain Controller Authentication certificate template
