Issue/Introduction

I run Federation Services from Web Agent Option Pack, and when I go to
the IDP page to authenticate, I'm refused access with 403 code, and
the logs show me that the Policy Server doesn't find the Service
Provider with the following lines :

I have already set Encoding="UTF-8" in server.xml file in the Application Server.

How can I solve this ?

Environment

Web Agent Option Pack 12.52SP1CR06 on Tomcat 6

Cause

 The Service Provider ID has accentuated character : "âme" which causes the issue.

Resolution

For Tomcat Application Server for Web Agent Option Pack : the
Connector elements must be configured to support UTF-8. This is
accomplished via setting URIEncoding="UTF-8".

Tomcat :

Set the URIEncoding attribute on the <Connector> element in server.xml
to something specific (e.g. URIEncoding="UTF-8").
