Pouziti HKFree LDAPu pro autentizaci je vcelku jednoduche.

  • Uzivatele maji login ve formatu XXX, kde XXX je jejich uid
  • Heslo je heslo v userdb
  • Synchronizace probiha jednou za den z userdb (vse mimo hesla)
  • base je dc=hkfree,dc=org

BASH

Je treba nainstalovat (aspon v debianu) ldap-utils. Dalsi potrebna vec je pridat do /etc/ldap/ldap.conf toto:

BASE    dc=hkfree,dc=org
URI     ldap://ldap.hkfree.org

TLS_CACERT      /etc/ssl/certs/hkfree.cer
TLS_REQCERT     try

Nyni si stahnete z https://igw.hkfree.org/download/CA/hkfree.crt do adresare /etc/ssl/certs/ a doinstalujte (v pripade potreby) balik openssl a libsasl2-modules

Jednoduchy test, jestli vse chodi je napriklad:

ldapsearch -U MOJE_ID -ZZ -h ldap.hkfree.org

update 28.10.2009:

ldapwhoami -U13 -w $heslo -ZZ
SASL/DIGEST-MD5 authentication started
SASL username: 13
SASL SSF: 128
SASL data security layer installed.
dn:uid=13,ou=people,dc=hkfree,dc=org

ldapwhoami -x -D"uid=13,ou=People,dc=hkfree,dc=org" -w $heslo -ZZ
dn:uid=13,ou=People,dc=hkfree,dc=org


Zmena hesla se da provest pomoci:

ldappasswd -U MOJE_ID -ZZ -h ldap.hkfree.org -S

atd.

Konfigurak pro Apache

  • je treba povolit mod_authnz_ldap a ldap (v apache2.x)
  • je treba mit spravne nastavene SSL (importovany korenovy certifikat hkfree) a ldap.conf
  • pro nejaky Directory/Location lze autentizace pouzivat takto:
               AuthType basic
               AuthBasicProvider ldap
               AuthLDAPURL "ldap://ldap.hkfree.org/ou=People,dc=hkfree,dc=org"
               AuthName "VPN"
               AuthLDAPRemoteUserIsDN off
               require valid-user
               AuthzLDAPAuthoritative off

PERL

viz http://ldap.perl.org

use Net::LDAP; 
use Authen::SASL;

my $ldapserver = "ldap://ldap.hkfree.org";
my $password = "heslo";
my $user = "uzivatel";
my $dn = "dc=hkfree,dc=org";

my $ldap = Net::LDAP->new($ldapserver, onerror => 'die' );

$ldap->start_tls(
        $verify => 'require'
        );

my $sasl = Authen::SASL->new(
  mechanism => 'CRAM-MD5 PLAIN ANONYMOUS',
  callback => {
    pass => $password,
    user => $user,
  }
);

my $mesg = $ldap->bind( $dn, sasl => $sasl, version => 3 );
