Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Application Server and        *

  ****************************************************************
  * PROBLEM DESCRIPTION: The OIDC TAI always transforms          *
  *                      newlines in POST data to <br>           *
  ****************************************************************
  * RECOMMENDATION:  Install a fix pack or interim fix that      *
  *                  contains this APAR.                         *
  ****************************************************************
  After successful authentication, the OpenID Connect (OIDC)
  Relying Party (RP) Trust Association Interceptor (TAI) always
  encodes the HTTP post data before redirecting to the
  target URL.  New line characters are always being
  transformed into <br> tags. Application developers may require
  that the new line characters remain in the POST parameters.
  

Problem conclusion

• The following OIDC TAI custom property is added:
  provider_<id>.encodeNewline, default=true
  
  When encodeNewline is set to false, the new line characters
  that exist in POST data will not be transformed into
  encoded <br> tags.
  
  The OIDC TAI is also updated so that, when it encodes the
  POST data, instead of replacing a new line with a <br>
  tag, it replaces with the encoded form of the tag, &lt;br;&gt;
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.15 and 9.0.0.11.  Please refer to the
