A few problems cause most authentication issues using certificates.

If a user cannot log on with their certificate, try one of these options to resolve the problem:

  • Verify that the user has not been disabled.

  • Verify that the certificate has not expired or been revoked.

  • Verify that the certificate is signed with the correct certificate authority.

  • Verify that the DN field is correct on the user configuration page.

  • Verify that the browser is providing the correct certificate.

  • Check the Audit Log for authentication messages.
