You will need to assign users in OneLogin before the connection will work. If you experience errors, try selecting Reapply entitlement Mappings under More Actions in the Settings of your OneLogin App.

If you have issues, you can use the SAML Tracer browser extension to check the process step by step. The errors shown in the tracker should help you to debug the issues. If it does not work, you can request help by sending an email at
