Re: LDAP authentication

$uid_attr = "uid";
$mail_attr = "mail";
$name_attr = "cn";
$ldap_server = "ldap.bb.cc.dd";
$ldap_port = 389;
$base_dn = "ou=People,o=bb.cc.dd";
$timezone_offset = 1;

This could be set in preferences with a slight hack, couldn't it?

Possibly with a yes/no setting to enable/disable LDAP authentication?

if ($xoopsConfig['ldap_auth'] != false) {
    $ldap_criteria = new CriteriaCompo(new Criteria('uname', $uname));
    $ldap_criteria->add(new Criteria('pass', $pwd));        
    $authenticated = $this->_uHandler->LDAPAuthentication($ldap_criteria, false);
}

This is exactly what I would expect in the next XOOPS release

thanks your work.

I wanted to check the LDAP password.
I added LDAP password check to your code.

function LDAPAuthentication($criteria = null)
    {
        $uid_attr = "uid";
        $mail_attr = "mail";
        $name_attr = "cn";
        $pass_attr = "userpassword";
                                    .
                                    .
                                    .
                    // Get info from LDAP (mail,name)
                    $sr = ldap_search($ds,$base_dn,$uid_attr."=".$criteria->crit
eriaElements[0]->value,Array($mail_attr,$name_attr,$pass_attr));
                                   .
                                    .
                                    .
                   if ($info["count"] == 1) {
                        $ldap_pass = ereg_replace("{CRYPT}", "", $info[0]["userpa
ssword"][0]);
                        if ($ldap_pass == crypt($pass, substr($ldap_pass,0,2))) {
                            // Search user in the DB
                                    .
                                    .
                                    .
                        }
                                    .
                                    .
                                    .

Hi hagane,

The password is already checked in the code previously provided. It is done during the bind process with the LDAP server

$ldapbind=ldap_bind($ds,$uid_attr."=".$criteria->criteriaElements[0]->value.",".$base_dn,$criteria->criteriaElements[1]->value);
      if($ldapbind) {
            //the user is authenticated
      }


Do you have any particular reason to do so ? I am interested...

By the way, you might want to have a look at this posthttps://xoops.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=19401&forum=14 for a more "pluggable" authentication mechanism that should be implemented in a future XOOPS release.

I'm sorry, it my mistake.
I used ldap_bind function that set manager's id and password.

thanks to your information.

Hi to all,
Im new here. I tried to use the previous hack in LDAP but it doesn't work in my site. I already modified the two files(user.php and member.php in kernel folder) but it seems it still authenticating in XOOPS db. I already specify our ldap server.

Did I miss something?

Thanks!

Hi evol13,

If you applied the hack step by step it should work. If the LDAP authentication fails, the hack automatically performs the default XOOPS authentication. I suggest you double check your LDAP parameters. What kind of LDAP server are you using: Active Directory, OpenLDAP, IPlanet, eDirectory, etc. ? Try to debug/add some "echo" to verify that the bind/connection to your LDAP server is OK.

I suggest you use this hack instead that will soon be included in the official XOOPS kernel (I hope this month)
https://xoops.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=19401&forum=14

The code is almost the same but you can quickly develop/test multiple authentication schemes without touching the kernel too much. And you can fall back to the default XOOPS authentication in 5 seconds by modifying only one string in your mainfile.php

Best regards,

Benoit

This hack allows you to authenticate your XOOPS users from an external LDAP repository. By default XOOPS authenticates users with passwords stored in the XOOPS MySQL database. By externalising the authentication process as explained in this hack and in a much better way inhttps://xoops.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=19401&forum=14
you could easily integrate XOOPS in an existing "authentication" infrastructure. Most companies are using an LDAP directory server (Active Directory, eDirectory, etc.) or another kind of centralised authentication server to authenticate their users centrally in a product "independant" way.

Hope this short explanation will help you to get the global picture...
