support authentication via Apache modules for integrations with SAML, Kerberos, LDAP, OpenID, ...
It would be useful if WHMCS allow authentication via standard Apache authentication modules. The Apache module does everything and provide app (WHMCS) username of authenticated user in REMOTE_USER Apache server variable.
I believe it is very simple to implement for you.
There are may authentication modules for Apache. It will allow WHMCS easily integrate with:
- SAML Shibboleth SP module (Microsoft Azure, Okta, Ping Identity, OneLogin, ...)
- OpenID Connect (Facebook, Google, Twitter, ...)
- LDAP (Active Directory, ...)
- and many others
