Public bug reported:

Changes to the Apache/WSGI implementation for Liberty (wsgi-
keystone.conf) requires editing the keystone-paste.ini file and
modifying the [composite:main] and [composite:admin] directives to
[composite:keystone-wsgi-public] and [composite:keystone-wsgi-admin],
respectively, otherwise the following error appears and the API returns
a 500 code to the client:

mod_wsgi (pid=874): Target WSGI script '/usr/local/bin/keystone-wsgi-admin' cannot be loaded as Python module.
mod_wsgi (pid=874): Exception occurred processing WSGI script '/usr/local/bin/keystone-wsgi-admin'.
