Products

• CA Single Sign-On

Issue/Introduction

Web Browser gets an HTTP 503 response when they attempt to access a protected resource through a Siteminder/Symantec Access Gateway

Cause

This issue occurs when the back-end application is offline or the Access Gateway server is routing incorrectly.

Environment

Release : 12.8.x

Component : SITEMINDER SECURE PROXY SERVER/Access Gateway

Resolution

1) Verify the back-end application is online

2) Verify that the Siteminder/Symantec Access Gateway proxy rules are directing the user to the correct server and URL.

A common way to test this is to point the web browser directly at the back-end application and verify whether the browser can access the resource.
