Redmine

I am not using Ruby currently and am simply trying to configure a device running Linux VERSION="5.15-kirkstone (kirkstone)" with an internally hosted lighttpd web server to use PAM authentication.

On the page
https://redmine.lighttpd.net/projects/lighttpd/wiki/mod_auth#pam-mod_authn_pam-since-lighttpd-1451
in section
pam (mod_authn_pam) (since lighttpd 1.4.51)
there is great information on setting up PAM authentication. It is all very easy to follow though one link is broken for creating /etc/security/http.access.conf file to define user/group access, see pam_acces. I have tried to figure out the setup but have gotten stumped.

What should the /etc/security/http.access.conf look like?

Thanks for any advice in advance!
