I've OIDC enabled a webapp and I am linking the users via email in the id_token. We have decided to use OIDC because it seemed newer and simpler to use. Now we need to implement SCIM with OIDC SSO; but when I search OneLogin > add apps, there seems to be only variations of SCIM Provisioner with SAML. Is it possible to use SCIM with OIDC or do I have to SAML enable the webapp.
SCIM specification doesn't seem to be dependent on SAML by itself.
SCIM Provisioner with SAML (and possibly other connectors) can be used for provisioning without filling SAML related fields. Therefore, it is possible to use two separate connectors, one for the OIDC connection and the other for the SCIM provisioning. Onelogin doesn't support a SCIM provisioning with OIDC type connector currently.
