Error description

• When trying to edit and update the httpd.conf file with
  "ServerTokens" variable, the changes do not take effect.
  
  Recreate Scenario:
  Recreate the issue as follows on WebSphere Application Server
  Network Deployment 6.1.0.17 with remote IBM HTTP Server
  webserver  6.1.0.13 (managed).
  
  1> Edited the httpd.conf locally on the remote IBM HTTP Server
  webserver and
  
  - add the following directive somewhere in between the file
  (not necessarily at the end) i.e
  
  
  ServerTokens Prod
  
  - add a virtualhost entry
  
  - save the httpd.conf file on the remote IBM HTTP Server
  webserver.
  
  2> Save httpd.conf and restart the IBM HTTP Server server
  
  3> Using the adminstrative console, edit httpd.conf file for
  the IBM HTTP Server webserver definition
  
  -add virtualhost entry
  
  4> using ISC propogate this change to the remote webserver.
  
  5>Restart the webserver on the remote machine.
  
  6> Open the httpd.conf locally on the webserver machine and you
  will see that the manual entry for Servertokens disappears
  (not the Virtualhost entry though) made in step 1.

  ****************************************************************
  A Change was made to the IBM HTTP Server Configuration file,
  to add directive "ServerToken". This change was removed
  after the customer used the administratiove console to create
  a Virtual Host in this same Web server configuration file. The
  Web server Virtual Host Wizard removed the directive
  "ServerToken"  due to an incorrect entry for default in an
  internal table used for syntax verification.
  

Problem conclusion

• The syntax  verification table was updated with the correct
  default value "FULL" for the IBM HTTP Server directive
  "ServerToken".
  
  The fix for this APAR is currently targeted for inclusion in
  fixpack 6.1.0.23.  Please refer to the Recommended Updates
