Issue/Introduction

We are getting multiple "Request Fail" errors upon logging into Identity Portal when SSO is integrated after applying 14.1 Identity Portal CP3, any new Hotfix on top of that or upgrade to 14.2. How can we resolve this?

Environment

Identity Portal CP3

Cause

This is due to SSO not configured to protect ‘jpg,png,jpeg,gif’ resources, Portal does not receive any authentication attribute and sends back 401 (unauthorized error) which is translated into ‘Request Fail’ on the UI, this is viewable on Web Browser console, on the Portal log you will see ‘Session not found’.

Resolution

To resolve this issue you need to have SSO protect the ‘jpg,png,jpeg,gif’ resources. 

1) Add/Edit realm – ‘/sigma/rest/resources’ and set it to be ‘Protected’, make sure GET and POST rules are included.
2) Under Agent Configuration Object – set ‘IgnoreExt’ attribute value to ‘.class,.fcc,.scc,.sfcc,.ccc,.ntc,.css,.js,.woff,.woff2,.svg,.ttf,.eot,.json’.
3) Clear SSO cache
