| When Jenkins is behind an Azure Application gateway it gets the proper header for the remote user passed to it - a complete header example is below: POST /job/deploy-job/build?delay=0sec HTTP/1.1

Content-Length: 0 HOWEVER the remote port is also included: X-Forwarded-For: 198.2.2.249:60769 and since the remote port changes with every request, the crumbs are never seen as valid. Jenkins should support stripping the port from the remote IP if present. I don't know what the Azure Application Gateway does for IPv6 since it doesn't support that yet. Related to (but not the same as) https://issues.jenkins-ci.org/browse/JENKINS-50767 as this is behind an Application Gateway (L7 proxy) rather than a Load Balancer. |
