We are not using OAuth though, we are using SAML SSO.
As per your idea for switching authenticationMode, I was under the impression that using basic authentication was impossible. As per this link
, VersionOne states themselves that "Once SAML SSO is enabled, all clients must use either SAML SSO or OAuth2 for authentication to the API endpoints." Additionally, my attempts to access the API on an out-of-network computer using correct credentials failed (and my in-network basic authentication attempts fail as well).
So, is there any way to use the API on our server through our SAML SSO enabled v1host besides making an account for that server which has SSO access?
