The Question is:
Is it possible to use OpenVMS' OS authentication in the Apache Web Server
Version 1.3.12 for OpenVMS Alpha?
The Answer is :
As of this writing, the OpenVMS external authentication API is not
currently documented nor supported.
Once this API is documented, anyone with access to the Apache source
code can conceivably add this support -- Compaq is aware of requests
for this support, and will consider its inclusion into a future version
of Apache for OpenVMS; once the API is available, of course.
