Okta Secure LDAP

Okta is commonly used for SSO with SAML but it also has a Secure LDAP interface which can be used for both authentication and authoritzation. This section documents the steps to add Okta as a Secure LDAP authentication source in ClearPass

ClearPass can work with any open LDAP based directory as an authentication and authorization source. Here are the steps to integrate ClearPass with Okta for LDAP authentication. This integration can be used with TACACS+ / Captive Portal / Onboard workflows amongst others

  1. Create an authentication source of type Generic LDAP
