ONELOGIN Product Notification

Critical Alerts

Dear OneLogin Administrator, 


We are scheduling a maintenance change for X-Forwarded-For (XFF) header support. This change will affect customers who access OneLogin via proxies and VPN where XFF headers are added to the request.   


This change will fix certain instances where the client IP has not been correctly forwarded in the XFF field. If your organization enforces blocking rules based on source IPs recorded in OneLogin events, you may observe a change in behavior due to the correct X-Forwarded-For address being applied following this change.
