The root cause of the problem is expired cryptographic keys.


Authentication Source: Series 7, LDAP or Active Directory

Diagnosing The Problem

Expired cryptographic keys can be identified by checking the timestamp of the folder csk, signkeypair, encryptkeypair and caserial.

Resolving The Problem

Recreate the encrypt key's.

When using a distributed environment, you need to perform the steps at the application server first. Afterwards, start the service and recreate the encrypt key's at the Gateway machine.


  1. Open Cognos Configuration and export the configuration
  2. Stop the IBM Cognos Service.
  3. Close Cognos Configuration
  4. Create a backup directory and move* following files and directories into this backup directory:
    - /c10/configuration/cogstartup.xml
    - /c10/configuration/csk
    - /c10/configuration/encryptkeypair
    - /c10/configuration/signkeypair
    - /c10/configuration/caserial
    - /c10/configuration/cogconfig.prefs

    *Please Note: These files/directories must be removed from the configuration directory. Copy without deleting will not solve the problem.
  5. Move the exported Configuration (Step 1) into the configuration directory (/c10/configuration) and rename this file to cogstartup.xml
  6. Open Cognos Configuration and save the configuration
  7. Start the Service
  8. When using a distributed environment, you need to repeat the steps 1 to 7 at the other machines too.
    (Content Manager first, Report Server afterwards, Gateway machine(s) at last)
  9. Try to login again

    If this problem still exists:
  10. Try to logon via the Dispatcher URI. You can find the Dispatcher URI in Cognos Configuration -> Environment.
    If this works restart the Web Server.

    If this problem still exists:
  11. Open Cognos Configuration and click on Environment. Change ALL ports in any new 'Dummy' values, e.g. port 80 into 81, port 9300 into 9301. Save the Configuration and start the service.
  12. Undo the changes of Step 8: Change the new 'Dummy' ports back to the old ports. Save the Configuration and Restart the Service.
  13. Try to the log in again.

    If this problem still exists:
  14. Recreate the ibmcognos Web Alias and the cgi-bin Web Alias in the Web Server administration. Make sure that the virtual directory is set correct. (E.g. If cgi-bin is set to an other installation directory this issue can occur.)
