I have a web server, Box A, which does not have many (shell) users. I have successfully implemented password-authentication to access various areas of the web site - Apache using mod_auth_pam, with a few tweaks to allow it to read the shadow password file. Obviously, this will only authenticate users of Box A. I have another server, Box B, which everyone uses. Is it possible to "relay" the PAM request from Box A to Box B, so that when faced with a password authentication request for a web page on Box A, the user is sucessfully logged in if they correctly enter their Box B username and password? Apologies if this is in any way a FAQ, but I have not been able to find anything that discusses this, at least not in as many words ... Both servers run Linux, kernel 2.2.x ...
