****************************************************************
When a Web Application is configured to authenticate users via
SSL certificates, WebSphere Application Server can be
configured to fall back to basic authentication, BasicAuth, if
certificate authentication fails. This is done by setting
custom security property
"com.ibm.wsspi.security.web.failOverToBasicAuth=true" or
checking the box "Default to basic authentication when
certificate authentication for the HTTPS client fails" from
Adminconsole panel "Global security > Web security - General
settings".
The failover to BasicAuth function was not working. Users
failing certficate authentication were not being prompted
BasicAuth credentials.

Problem conclusion

Code has been changed to allow failover to BasicAuth
credentials when configured as such.

The fix for this APAR is currently targeted for inclusion in
fix pack 8.5.5.13 and 9.0.0.5.
