APAR status

• Closed as program error.

Error description

• When the clients access OIDC protected resources without the
  authentication, the RP runtime redirects the clients (to OP)
  by sending the response code 200 and also includes a
  javascript in the response. This will be a problem for the
  clients that cannot support javascript and/or stop the
  request processing when they see the 200 response code.

  When the clients access OIDC protected resources without the

  the response. This will be a problem for the clients that cannot
  support javascript and/or stop the request processing when they
  see the 200 response code.
  

Problem conclusion

• Add an OpenID Connect relying party (RP) config option to
  specify whether to do the client side redirect. The new option
  is "isClientSideRedirectSupported" and default value is "true".
  If the clients cannot handle either javascript or the response
  code 200, then they can set this new configuration option to
  "false".
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 8.5.5.9.  Please refer to the Recommended Updates page for
