If a user has more than 150 group claims Azure by design switches from sending the groups through SAML to sending a query response. ESRI has not built in the compatibility to handle this. Just wondering if more large organizations have ran into this and if we can push esri to fix.
This is logged as known BUG-000123928 for Portal for ArcGIS
Hi,
For workarounds to the Azure SAML assertion limit of 150 for group memberships, please see: Workaround the Azure SAML assertion group size limit .
