Ok, so no way to get to single_sign_on_record then?
Am I understading the code you referred to correctly, in that I should supply a field named “custom_external_id” with my SSO - then it will save to the custom field “custom_external_id” (it has to be prefixed “custom”), right?
Is there an easier way to traverse all users and set the new custom field, other than to write a script that calls sync_sso on the thousands of users? It seems a lot of work to get to a field we already have in the system
