Problem conclusion


    

  • The OIDC TAI is updated to support PKCE when authenticating by
using the code authorization flow.

The TAI always sets the code_challenge_method to S256 when it
uses PKCE. code_challenge_method=plain is not supported.

The fix for this APAR is targeted for inclusion in fix pack
8.5.5.25 and 9.0.5.17. For more information, see 'Recommended
Updates for WebSphere Application Server':
