Issue:

 

Upon accessing Single Sign-On (Siteminder) protected resources hosted on IIS, user is getting HTTP Server Error 500 after successful authentication and authorization.

  

 

 

Cause:

 

  • Siteminder Web Agent logged the successful Siteminder authentication and authorization, but not the HTTP Server Error 500.
  • Web.config file (residing under the protected resource’s physical folder) registered missing partial precondition with the Siteminder Web Agent ISAPI filter:
<filter name="SiteMinder Agent" path="D:\Program Files\CA\webagent\win64\bin\ISAPI6WebAgent.dll" enabled="true" enableCache="false" preCondition="bitness64" /> 
 
Resolution:

 

Ensure that 32-bit or 64-bit Siteminder Web Agent ISAPI filter is defined in the web.config file accordingly, with the following format:
<filter name="SiteMinder Agent" path="C:\CA\webagent\win64\bin\ISAPI6WebAgent.dll" enabled="true" preCondition="classicMode,bitness64" />


<filter name="SiteMinder Agent-32" path="C:\CA\webagent\win32\bin\ISAPI6WebAgent.dll" enabled="true" preCondition="classicMode,bitness32" />
