AWX (19.3.0) Enable SSO

Hi team

I had configured SAML in version 14, then upgraded to version 17.1.0, it worked, no specific problem.

I just reinstalled AWX completely in version 19.3.0 with awx-operator, everything works too, except SSO.

I can’t figure out how to reactivate it.

In version 17, I had these backend available in the API

“AUTHENTICATION_BACKENDS”: [
“awx.sso.backends.TACACSPlusBackend”,
“awx.sso.backends.SAMLAuth”,
“django.contrib.auth.backends.ModelBackend”
],

In version 19.3

“AUTHENTICATION_BACKENDS”: [
“awx.sso.backends.TACACSPlusBackend”,
“awx.main.backends.AWXModelBackend”
],

I was wondering if SAML has become an exclusive feature of Ansible Tower (and thus paid for)?

Thank you
Charles
