Environment

NetIQ Access Manager 3.2
NetIQ Access Manager 3.2.2
NetIQ Access Manager 3.2.2 IR2
NetIQ Access Manager 4.0
NetIQ Access Manager 4.1

Situation

  • SAP Crystal Reports installed on a Microsoft IIS 7.0 web server
  • NetIQ Access Gateway has been configured to protect the SAP Crystal Reports application server
  • Some ASP report pages cannot be retrieved (browser client renders a blank page)

Resolution

Please review your SAP Crystal Reports server configuration in order to fix the corrupt content-length header

Cause

The SAP Crystal Reports application server returns a corrupted / illegal HTTP 1.1 "content-length" header. Instead of sending the length value it sends the length value twice separated with a comma.
Example:
Status:200 200 OK
Cache-Control: private
Content-Length: 40851,40851
Content-Type: application/x-epf
