JR51883: WSDL DISCOVERY DOES NOT PREEMPTIVELY SEND CONFIGURED AUTHENTICATION CREDENTIALS

8.0.1.3-WS-BPM-IFJR51883
Version 8.5 Refresh Pack 6 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• The WSDL discovery function in IBM Process Designer does not
  preemptively send the configured basic authentication
  credentials but waits for the authentication challenge from the
  web service and then sends the credentials in a second request.
  As a result, the WSDL discovery function might fail in certain
  scenarios.
  

Local fix

Problem summary

• The WSDL discovery function uses an HTTP client to reach out to
  the URL, providing a WSDL file. This HTTP client does not use
  preemptive authentication but rather attempts a call without
  having credentials, which, according to the HTTP protocol,
  results in an HTTP 401 response. According to the HTTP protocol,
  the HTTP client then retry the same call, this time with the
  credentials. While this works fine in most scenarios, there are
  certain environments where the credentials must be sent with
  the first request.
  

Problem conclusion

• A fix is available for IBM BPM V8.0.1.3 that enables the
  preemptive authentication in WSDL discovery scenarios so that
  credentials are sent with the first HTTP request when they are
  available, rather than waiting for the authentication challenge
  before sending the credentials.
