[pmwiki-users] Using IP's in PmWiki

[Michael Brenner]

Hi there,

lately I had an idea for an ip-based authentication. This might be userful for 
Intranet's also having webwide access. There are two useful ways in using 
IP's (see below). My questions are, is this worth added to the cookbook and 
will it work that fine like I'm thinking?

--code for local/config.php--

// Visitors from subnet have authenticated status via IP
// All Visitor can login

//hint: (:if !enabled AuthPw)[[{$Title}?action=login|Login]](:endif:) to make 
// login link still works for user-based authorisation

/*
if((ip2long($_SERVER['REMOTE_ADDR'])&ip2long('255.255.255.0'))==ip2long('192.168.10.0')) 
{
  //local ip
  SDV($AuthId, $_SERVER['REMOTE_ADDR']);//don't set if visitor isauthenticated
}
$Author=$AuthId;
*/
/*
//////////////////////////////////////////////////////////////////////////////////////////////////////////

// --Plan B--
// Only visitors from local net are able to login

// in Site.AuthForm: change (:if:)$[Password]: (:input password name=authpw:)
// to (:if enabled EnableAuthUser:)$[Password]: (:input password name=authpw:)
// and add (:if !enabled EnableAuthUser:)Sorry, login disabled(:ifend:)

// hint: Use (:if expr !enabled AuthPw and enabled EnableAuthUser:)
// [[{$Title}?action=login|Login]](:ifend:)

$Author=$AuthId;
if((ip2long($_SERVER['REMOTE_ADDR'])&ip2long('255.255.255.0'))==ip2long('192.168.10.0'))
{
  //local ip
  $EnableAuthUser=1;
} else {
  $EnableAuthUser=0;
}
