    A 403 error may occur when the OpenID Connect Relying Party is
    a partner with an OpenID Connect provider that URL encodes the
    state parameter.
    

Problem conclusion

  • The OpenID Connect specification states that the state
    parameter must be returned to the client without modification.
    Because of the way that the WebSphere OpenID Connect Relying
    Party (RP) is constructing the state parameter, if the OpenID
    Connect provider (OP) sanitizes the state parameter by URL
    encoding it, the state parameter will appear to be modified
    and a 403 error will result.
    
    The OpenID Connect RP is modified to ensure that the state
    parameter is created in a way that URL encoding it will not
    change its contents.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.0.0.13, 8.5.5.11 and 9.0.0.2.  Please refer to the
