AWX 15.0.1 and OKTA SAML

Has anybody set up AWX 15.0.1 with OKTA SAML…(had to downgrade from 17.x and do not want to go to 21 due to it no longer uses docker) I have all the SAML service provider configuration working correctly, but when I authenticate via OKTA/SSO login it brings me back to the login prompt. I tried configuring the SAML Organizational Map and SAML Organization Attribute mapping but still have no luck… any insights would be greatly appreciated.
