4     Document manager handling for authentification of users
5     based on:
6     * refearer header from remote browser (it's really easy to forge this)
7     * remote IP address
8     * remote DNS hostname
9    
10     Written by Dobrica Pavlinusic <dpavlin@rot13.org>
11    
12     Usage example:
13    
14     docman.conf:
15    
16     $gblUsers = "htusers_header";
17    
18     .htusers examples:
19    
20     REMOTE_ADDR=10.0.0.3:Dobrica (client ip):auth_header:dpavlin@foo.bar
21     will match exact IP adress
22     remote_hostname=hbreyer2:Dobrica (hostname):auth_header:dpavlin@foo.bar
23     will match exact hostname
24     http_referer=test.foo.bar:Dobrica (by referer):auth_header:dpavlin@foo.bar
25     will match user which comes from site test.foo.bar
