RE: [webmin-l] External squid-style authentication program ?

[Dave I. <dav...@en...>]

Thanks, I will look into that.

What about enhanced login using multiple-factor authentication? I am
thinking here of an interactive login, where there is a username/password
challenge, followed by an Entrust Identity Guard challenge (on a new page).
I am assuming that to do this I will have to customize the Webmin login page
beyond what is supported in the configuration.  Which Webmin scripts should
I be looking at to do this?

Thanks

Dave I

Yes.  There are several that come with Squid.  On a Red Hat system 
they'll be in /usr/lib/squid.  There are quite a few others on the web 
in varying states of quality.  Writing ones own is not difficult, as 
you've seen.

BTW-the standard way to solve your problem is to put Perl into 
unbuffered mode at the start of the code (but a flush works fine too). 
You can do that with:

$|=1;

Somewhere early in the file.  When things get complicated, it's nice to 
not have to think about flushing after every result.

The Squid FAQ has a lot of good information about authenticators.
