## Symptoms

- * Although the Mobile Access Portal is set to use a user certificate for authentication, the portal does not prompt the MacOS user for this certificate. On a Windows device, there is no issue and the user is always prompted.
* The following authentication error appears:

  ```
  
  [5568][26 Feb 7:50:34][RPC] Response: (192) (
  :value (GetAuthenticationInfoResponse
  :m_authenticateCertificateFirst (int
  :value (0)
  )
  :m_mdmPortalCookie (string
  :value ()
  )
  :m_errorCode (int
  :value (2)
  )
  )
  )
  ```

* CCplogUtils::FillVarArg: str: SSL renegotiation fails with the following error: ` "No client certificate was provided."`

## Cause

This behavior is caused by MacOS keychain infrastructure.

The error itself indicates only that once the MacOS browser is not able to use a certificate, a handshake error occurs as expected. When the certificate is seen on the Security Gateway, there are no errors, which means that this is not a Gateway-side issue.
