Closed as program error.
Error description
CICS has a TCPIPSERVICE with AUTHENTICATE(BASIC). If the client did not provide any credentials or the credentials were invalid then CICS will respond with an HTTP 401 response. The web error program, DFHWBEP, has not been driven for this error which means that these failures could not be logged or audited. Additional symptoms: migrating from 5.2 to 5.5 you experience an ABEND WBEP issued from your user replaceable module DFHWBEP.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: DFHWBEP not invoked by DFHWBXN * * following a basic authentication * * error. * **************************************************************** CICS has a TCPIPSERVICE defined with AUTHENTICATE(BASIC). A client sends in an HTTP request that does not contain any credentials or contains invalid credentials. This causes CICS to respond with an HTTP 401 response. The web error program, DFHWBEP, is not driven for this error case so the failure is unable to be logged or audited. KEYWORDS: server WBEP 401 wbep_http_response_code
Problem conclusion
The web error program will now be driven for basic authentication errors. Customers should review their use of the program to validate its behaviour when presented with a 401 response code.
