apache openvms username verification

Marco van der Sijpt — Fri, 30 Jul 2004 04:44:04 GMT

I'm a dutch system manager trying to figure out how to verify access on certain directories on disks. I can verify the username through the openvmsmodule / apache combination but once I try to verify access on certain directories by means of the www_remote_user symbol I get failures. Can anyone tell me how I can get the www_* symbols into the process context.
Please send response also to:

AFAIK, the www_ prefix is not used with Apache. Try REMOTE_USER instead.

Hi Marco,

have a look at the

[.APACHE.CGI-BIN]TEST-CGI-VMS.COM that comes with the distribution. This will show most of the variables set by Apache (REMOTE_USER is not in there since it is only set if you have an authenticated user I assume). Especially note that environment settings are not prefixed with
WWW_* like they are e.g. for the OSU server.

Greetings, Martin

Marco - you will need something like this in you HTTPD.CONF file :-

Options -Indexes Includes FollowSymLinks Multiviews
AllowOverride None
AuthType Basic
AuthName "WebReport Logon"
AuthOpenVMSGroup Off
AuthOpenVMSAuthoritative On
AuthUserOpenVMS On
require valid-user
Order deny,allow
Deny from all
Allow from all

You mau also need to load it as a module :-

LoadModule auth_openvms_module /apache$common/modules/mod_auth_openvms.exe_alpha

While I'm at it, you can also do a neet trick of authenticating against UAF and a file :-

Options -Indexes Includes FollowSymLinks Multiviews
AllowOverride None
AuthType Basic
AuthName "Web-CMS Logon"
AuthOpenVMSAuthoritative On
AuthOpenVMSGroup off
AuthGroupFile /cms$data/cms_group.prot
AuthOpenVMSUser On
require group cmsusers
Order deny,allow
Deny from all
Allow from all

You then simply create a file, in this case cms$data:cms_group.prot and place the usernames in against the group:-

cmsusers: MFM mfm NZC nzc DZL dzl DHU dhu CML cml

The reason for upper and lowercase is that Apache is case-sensitive, so I capture both logins.

Hope this helps, Rob.

Slightly midread your original request, although the answer I gave will give you directory level authentication.

Here is some code I use for checking authentication for specific usernames, based on REMOTE_USER :-
