  an OP if its web server is requiring a Content-Security-Policy.

  The OIDC TAI cannot send a Content-Security-Policy
  HTTP header on the authentication request to the OP.  The
  WebSphere OIDC RP cannot interoperate with an OP if its web
  server is requiring a Content-Security-Policy.
  

Problem conclusion

• The OIDC RP TAI is updated to allow the
  Content-Security-Policy HTTP header to be sent to the OP on
  the authentication request.
  
  The following OIDC RP TAI custom property is added:
  provider_.contentSecurityPolicy
  
  This property is optional and does not have a default value.
  
  If you want a Content-Security-Policy HTTP header to be
  included in the initial login request that is sent to your OP,
  set the provider_<id>.contentSecurityPolicy property to the
  value that you want to use for the Content-Security-Policy
  HTTP header.  If your Content-Security-Policy value requires a
  nonce, you can use the %NONCE% keyword to indicate where the
  nonce should be placed in the text.  For example:
  script-src 'self' 'nonce-%NONCE%' ; object-src 'self';
  frame-src 'self'
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.17, 9.0.5.3.  Please refer to the Recommended
