Nethserver-dokuwiki ldap auth problem when connected to a remote ldap bind

m.traeumner · June 14, 2019, 12:42pm

I think at LDAP server URL you only have to set the server url without the port.

I cannot reproduce

ok got it you used a remote ldap provider, no tested in that scenario, it should work OTB, will try when I got time

Indeed, that’s strange. I don’t how I end up with such a configuration… But it works

pagaille · June 25, 2019, 1:25pm

I removed the “:636” at the end of the LDAP server URI field in the server manager, now it’s ok for Dokuwiki.

I also set “No” for STARTTLS in the UI but that parameter looks not being taken into account by the template, I had to set it to “0” manually in the configuration file.

So the most annoying problem is the inability to login using an email address…

stephdl · June 25, 2019, 3:19pm

Sorry, I did not find time to dive inside your issue, will try to check and to reproduce the remote ldap account, but can you login with a local account provider (dokuwiki hosted on the same server) with the email ’ address?

pagaille · June 25, 2019, 6:57pm

Just tested.

With AD : works OTB
With DC : authentications is done with uid, not with email.

So the problem is not related to a non-localhost ldap server install but because of DC.

pagaille · June 25, 2019, 7:02pm

/etc/dokuwiki/local.protected.php :

AD :

$conf['authtype'] = 'authad';
$conf['plugin']['authad']['account_suffix']     = '@gaillet.be';
$conf['plugin']['authad']['base_dn']            = 'dc=ad,dc=gaillet,dc=be';
$conf['plugin']['authad']['domain_controllers'] = 'ldaps://ad.gaillet.be'; //multiple can be given


$conf['useacl'] = 1;

DC :

$conf['authtype'] = 'authldap';
$conf['plugin'][$conf['authtype']]['server'] = "ldap://127.0.0.1:389";
$conf['plugin'][$conf['authtype']]['version'] = '3';
$conf['plugin'][$conf['authtype']]['usertree'] = "ou=People,dc=directory,dc=nh";
$conf['plugin'][$conf['authtype']]['grouptree'] = "ou=Groups,dc=directory,dc=nh";
$conf['plugin'][$conf['authtype']]['userfilter'] = '(&(uid=%{user})(objectClass=inetOrgPerson))';
$conf['plugin']['authldap']['groupfilter']  = '(|(memberUid=%{user})(gidNumber=%{gid}))';
$conf['plugin'][$conf['authtype']]['groupkey'] = 'cn';
$conf['plugin']['authldap']['binddn']     = "cn=ldapservice,dc=directory,dc=nh";
$conf['plugin']['authldap']['bindpw']     = "********************";
$conf['plugin']['authldap']['starttls']   = 1;
$conf['plugin']['authldap']['modPass'] = 0;


$conf['useacl'] = 1;

Very different.

stephdl · June 26, 2019, 5:54pm

yes with samba4 you use the self bind, so the user authenticates himself

stephdl · June 26, 2019, 5:59pm

I retrieve the data, directly from NethServer::SSSD, so it is probably a matter to bind the good data, but I do not know if I could offer user and email address

github.com

stephdl/nethserver-dokuwiki/blob/ns7/root/etc/e-smith/templates/etc/dokuwiki/local.protected.php/10auth

{

use esmith::util;
use NethServer::SSSD;
my $sssd = new NethServer::SSSD();

my $quotedBindPass = $sssd->bindPassword();
$quotedBindPass =~ s/\'/\\'/g;

#specific OpenLDAP
my $server = $sssd->ldapURI() .':'. $sssd->port();
my $usertree = $sssd->userDN();
my $grouptree = $sssd->groupDN();
my $binddn = $sssd->bindDN();

#specific Samba4 AD
my $host = $sssd->ldapURI();
my $baseDN = $sssd->baseDN();
$tls = $sssd->startTls();

This file has been truncated. show original

However why you went to openLdap

pagaille · June 26, 2019, 6:21pm

It’s so lightweight and easy to install compared to the bloated MS-stylish AD !

stephdl · June 26, 2019, 7:50pm

for now modify, of course the next template-expand and update will remove your change

- $conf['plugin'][$conf['authtype']]['userfilter'] = '(&(uid=%{user})(objectClass=inetOrgPerson))';
+ $conf['plugin'][$conf['authtype']]['userfilter'] = '(&(mail=%{user})(objectClass=inetOrgPerson))';

pagaille · June 26, 2019, 7:53pm

I think I tried that (see post #7), it works but we loose the group association (which is useful for ACL)

stephdl · June 26, 2019, 7:54pm

thank for the hint
you have a debug that is useful to play

$conf['plugin']['authldap']['debug'] = 1;

stephdl · June 26, 2019, 8:32pm

I think I got it, please could you test this fix in /etc/dokuwiki/local.protected.php

...
$conf['plugin'][$conf['authtype']]['userfilter'] = '(|(uid=%{user})(mail=%{user}))';
$conf['plugin']['authldap']['groupfilter']  = '(memberUid=%{uid})';
...
$conf['plugin']['authldap']['debug'] = 1;

add also the full email of the admin inside /etc/dokuwiki/local.php

$conf['superuser'] = 'admin,admin@nethservertest.org';

stephdl · June 26, 2019, 9:17pm

$conf['plugin']['authldap']['starttls']   = 1;

this is a bug now I retrieve the startTls from NethServer::SSSD (0 or 1)

stephdl · June 28, 2019, 6:04am

@pagaille would you mind to test the ldap fix, just cp and paste in the php file.

pagaille · June 28, 2019, 12:12pm

Yep. Working

Well done cpt code cruncher And thanks !!

stephdl · June 28, 2019, 1:20pm

Please don’t tell that to others, but I am just a guy who try and try until it works
