Troubleshooting
Problem
When attempting to use a Custom HTTP Header variable to authenticate against Cognos Analytics 11.x, Users are still prompted to log into Cognos with Basic Signon.
Symptom
Users are prompted to log into the Cognos login page.
Custom HTTP Header variable is not being used to Authenticate against the LDAP Server.
External Identity LDAP filter is not being generated.
Cause
The Custom HTTP Header variable is not being passed from Internet Information Services (IIS), through the proxy/url rewrite. Due to not being passed, Cognos Analytics cannot use it to be turned into the LDAP search filter identified by the External Identity Mapping
Environment
Windows
Application Request Routing (ARR)
URL Rewrite
Cognos Analytics 11.x
Internet Information Services (IIS)
Resolving The Problem
In IIS Manager, create the Custom HTTP Header variable beneath Server Variables and associate it to the Headers rule under the /ibmcognos/bi path.
To determine the best method of implementing this HTTP Header variable, you must consult with your IIS Web Administration team, or Microsoft.
