Debian (Squeez) SAMBA PDC Avec Annuaire Openldap - { Prog En Vrac } Debian (squeez) SAMBA PDC avec annuaire OpenLDAP - { Prog en vrac } http://www.progenvrac.com/spip.php?article19 AccueilLinux Rechercher Debian (squeez) SAMBA PDC avec annuaire OpenLDAP 24 sep par senti Linux 37 commentaires Suite à l’arrivée récente de Windows 7 pro dans mon entreprise, j’ai voulu ajouté mes machines sur mon contrôleur de domaine SAMBA (3.2.5) et malheureusement j’ai eux la surprise de découvrir que mon windows 7 n’arrivait pas à dialoguer avec mon contrôleur de domaine. J’ai donc attaqué les recherches pour savoir si d’autres personnes avait le même soucis... Et apparemment oui.... La version 3.2.5 n’est pas compatible avec windows 7... J’ai donc décidé de tester avec la distribution testing de debian, pour savoir si cela fonctionnerai avec la nouvelle version de samba. Voici donc le tutoriel issue de cette installation, en ésperant qu’il puisse servir à nombre d’entre vous. 1. Prérequis Tout d’abord nous allons changer le niveau de debconf par défaut celui-ci est sur dialogue et élevé. Nous allons le 1 sur 38 07/05/12 10:31 Debian (squeez) SAMBA PDC avec annuaire OpenLDAP - { Prog en vrac } http://www.progenvrac.com/spip.php?article19 reconfigurer en dialogue et intermédiaire. Pour cela faire un : dpkg-reconfigure debconf 2. Installation de openLDAP (2.4.23) 2.1 Installation des paquets apt-get install slapd ldap-utils ldapvi Lors de cette installation un certain nombre de questions seront posées : Faut il omettre la configuration d’OpenLDAP ? Non Nom de domaine : dev.net Nom de votre organisation : dev Mot de passe administrateur : ******** Faut-il autoriser le protocole LDAPv2 : Non Attention : Dans la nouvelle version d’openldap le fichier slapd.conf n’existe plus il est remplacé par le répertoire /slapd.d, Nous verrons comment faire par la suite pour ajouter le nouveau schéma samba. 2.2 Installation de phpldapadmin (1.2.0.5) Afin de visualiser notre nouveau LDAP, je vous propose l’installation de phpldapadmin qui nous permettra de visualiser plus simplement notre annuaire ldap qui pour l’instant ne contient pas grand chose. Il est important aussi de noter que l’installation de celui-ci à un peu changé aussi. apt-get install phpldapadmin 2 sur 38 07/05/12 10:31 Debian (squeez) SAMBA PDC avec annuaire OpenLDAP - { Prog en vrac } http://www.progenvrac.com/spip.php?article19 Lors de l’installation un certain nombre de question seront posées : Adresse du serveur LDAP : 127.0.0.1 (si votre annuaire est sur un autre serveur donnez lui son adresse biensûr) Faut-il gérer le protocole LDAPS : non Nom distinctif de la base de recherche : dc=dev, dc=net Type d’authentification : session (vous avez le choix entre session, cookie, config) Identifiant dn de connexion au serveur LDAP : cn=admin,dc=dev, dc=net Serveur web à reconfigurer automatiquement : apache2 (vous avez le choix entre apache, apache-ssl, apache-perl et apache2). Faut-il redémarrer le serveur web : oui Une fois l’installation terminée allez sur un poste qui dispose d’un navigateur internet et testez si phpldapadmin est bien installé. http://X.X.X.X/phpldapadmin/ Une fois sur l’interface vous pouvez vous connecter à votre annuaire en tant qu’admin avec votre mot de passe administrateur LDAP. 2.3 Installation du schéma samba L’installation de ce schéma est essentiel car il contient les attributs nécessaire au LDAP pour la bon dialogue avec samba en PDC. apt-get install samba-doc Puis ensuite 3 sur 38 07/05/12 10:31 Debian (squeez) SAMBA PDC avec annuaire OpenLDAP - { Prog en vrac } http://www.progenvrac.com/spip.php?article19 gunzip -c /usr/share/doc/samba-doc/examples/LDAP/samba.schema.gz > /etc/ldap/schema/samba.schema Une fois cette étape finie dans l’ancienne version il sufsait d’ajouter le schema dans slapd.conf. Mais avec la nouvelle version de samba quand on fait un ls -l /etc/ldap/slapd.d/cn=config/cn=schema on obtient : -rw------- 1 openldap openldap 15474 24 sept. 13:39 cn={0}core.ldif -rw------- 1 openldap openldap 11308 24 sept. 13:39 cn={1}cosine.ldif -rw------- 1 openldap openldap 6438 24 sept. 13:39 cn={2}nis.ldif -rw------- 1 openldap openldap 2802 24 sept. 13:39 cn={3}inetorgperson.ldif et on constate que notre schéma n’est pas présent. La solution (qui n’est peut etre pas la bonne, car j’avoue avoir cherché longtemps sans en trouvé de meilleur et la doc d’openldap est très très chiante à comprendre) est de creer un fichier /etc/ldap/slapd.conf manuellement et d’y inclure les schémas nécessaires. Attention il faut remettre les anciens schéma sous peine d’avoir un message d’erreur. vim /etc/ldap/slapd.conf puis include /etc/ldap/schema/core.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/nis.schema 4 sur 38 07/05/12 10:31 Debian (squeez) SAMBA PDC avec annuaire OpenLDAP - { Prog en vrac } http://www.progenvrac.com/spip.php?article19 include /etc/ldap/schema/inetorgperson.schema include /etc/ldap/schema/samba.schema Et on sauvegarde en sortant. Une fois ce fichier créer on lance la commande suivante qui convertira au nouveau format : slaptest -f /etc/ldap/slapd.conf -F /etc/ldap/slapd.d/ la commande doit vous retourner config testing succeeded. Si on refait un petit ls -l /etc/ldap/slapd.d/cn=config/cn=schema on constate que le schéma est bien ajouté, mais que le propriétaire est root et non openldap comme ci-dessous. -rw------- 1 openldap openldap 15474 24 sept. 13:39 cn={0}core.ldif -rw------- 1 openldap openldap 11308 24 sept. 13:39 cn={1}cosine.ldif -rw------- 1 openldap openldap 6438 24 sept. 13:39 cn={2}nis.ldif -rw------- 1 openldap openldap 2802 24 sept. 13:39 cn={3}inetorgperson.ldif -rw------- 1 root root 12492 24 sept. 14:13 cn={4}samba.ldif on va donc lancer les commandes suivantes pour lui donner les droits chown openldap:openldap /etc/ldap/schema/ -R chown openldap:openldap /etc/ldap/slapd.d/ -R Un fois ces commandes exécuté on peut enfin faire un redémarrage du serveur ldap. /etc/init.d/slapd restart 5 sur 38 07/05/12 10:31 Debian (squeez) SAMBA PDC avec annuaire OpenLDAP - { Prog en vrac } http://www.progenvrac.com/spip.php?article19 3. Installation de SAMBA Nous allons maintenant attaquer la partie PDC avec samba. Pour cela nous allons installer un certain nombre d’éléments (samba, smbclient, smbfs,smbldap-tools). apt-get install samba smbclient smbfs smbldap-tools Lors de l’installation de samba un certain nombre de questions seront posées : Nom du domaine ou groupe de travail : DEV Voulez vous chifrer les mots de passe : Oui Modifier smb.conf pour utiliser les paramètres WINS fournis par DHCP : Non Comment voulez-vous lancer Samba : Demon Faut-il créer une base de données /var/lib/samba/passdb.tdb : Non Une fois l’installation du serveur SAMBA efectuée, arretez le service samba en faisant : /etc/init.d/samba stop 3.1 Configuration du fichier smb.conf Avant toute chose faire une copie de sauvegarde du fichier d’origine (on est jamais assez prudent hein :p) cp /etc/samba/smb.conf /etc/samba/smb.conf.save Une fois la copie efectuée, éditez le fichier smb.conf avec votre éditeur préférer et changer les paramètres à l’intérieur. Voici ci-dessous mon fichier smb.conf pour plus de simplicité. 6 sur 38 07/05/12 10:31 Debian (squeez) SAMBA PDC avec annuaire OpenLDAP - { Prog en vrac } http://www.progenvrac.com/spip.php?article19 [global] workgroup = DEV server string = Controleur de domaine netbios name = developpement domain master = yes local master = yes domain logons = yes client lanman auth = yes client ntlmv2 auth = yes lanman auth = yes ntlm auth = yes security = user os level = 40 ldap ssl = off ldap passwd sync = yes passdb backend = ldapsam:ldap://127.0.0.1 ldap admin dn = cn=admin,dc=dev,dc=net ldap suffix = dc=dev,dc=net ldap group suffix = ou=Groups ldap user suffix = ou=Users ldap machine suffix = ou=Machines add user script = /usr/sbin/smbldap-useradd -m "%u" ldap delete dn = yes delete user script = /usr/sbin/smbldap-userdel "%u" add machine script = /usr/sbin/smbldap-useradd -w "%u" add group script = /usr/sbin/smbldap-groupadd -p "%g" #delete group script = /usr/sbin/smbldap-groupdel "%g" add user to group script = /usr/sbin/smbldap-groupmod -m "%u" "%g" delete user from group script = /usr/sbin/smbldap-groupmod -x "%u" "%g" 7 sur 38 07/05/12 10:31 Debian (squeez) SAMBA PDC avec annuaire OpenLDAP - { Prog en vrac } http://www.progenvrac.com/spip.php?article19 set primary group script = /usr/sbin/smbldap-usermod -g "%g" "%u" logon path = \\%L\profiles\%U logon drive = P: logon home = \\%L\%U socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 case sensitive = No default case = lower preserve case = yes short preserve case = Yes #character set = iso8859-1 #domain admin group = @admin dns proxy = No wins support = Yes winbind use default domain = Yes nt acl support = Yes msdfs root = Yes hide files = /desktop.ini/ntuser.ini/NTUSER.*/ # autre possibilité "veto files = " # # Reglage de l'encodage des caracteres : unix charset = iso-8859-15 display charset = iso-8859-15 dos charset = 850 # [netlogon] path = /home/dev/netlogon writable = No browseable = No write list = Administrateur 8 sur 38 07/05/12 10:31 Debian (squeez) SAMBA PDC avec annuaire OpenLDAP - { Prog en vrac } http://www.progenvrac.com/spip.php?article19 # [profiles] path = /home/dev/profiles browseable = No writeable = Yes profile acls = yes create mask = 0700 directory mask = 0700 # [homes] comment = Repertoire Personnel browseable = No writeable = Yes # [partage] comment = Repertoire commun browseable = Yes writeable = Yes public = No path = /home/partage # [printers] comment = All Printers path = /var/spool/samba create mask = 0700 printable = Yes browseable = No # [print$] 9 sur 38 07/05/12 10:31 Debian (squeez) SAMBA PDC avec annuaire OpenLDAP - { Prog en vrac } http://www.progenvrac.com/spip.php?article19 comment = Printer Drivers path = /var/lib/samba/printers Une fois le fichier smb.conf sauvegardé il va falloir créer les répertoires pour les scripts de connexion, les profiles itinérants ainsi que le partage sur le serveur.

  • Samba-3 by Example
    Samba-3 by Example Practical Exercises in Successful Samba Deployment John H. Terpstra May 27, 2009 ABOUT THE COVER ARTWORK The cover artwork of this book continues the freedom theme of the first edition of \Samba-3 by Example". The history of civilization demonstrates the fragile nature of freedom. It can be lost in a moment, and once lost, the cost of recovering liberty can be incredible. The last edition cover featured Alfred the Great who liberated England from the constant assault of Vikings and Norsemen. Events in England that finally liberated the common people came about in small steps, but the result should not be under-estimated. Today, as always, freedom and liberty are seldom appreciated until they are lost. If we can not quantify what is the value of freedom, we shall be little motivated to protect it. Samba-3 by Example Cover Artwork: The British houses of parliament are a symbol of the Westminster system of government. This form of government permits the people to govern themselves at the lowest level, yet it provides for courts of appeal that are designed to protect freedom and to hold back all forces of tyranny. The clock is a pertinent symbol of the importance of time and place. The information technology industry is being challenged by the imposition of new laws, hostile litigation, and the imposition of significant constraint of practice that threatens to remove the freedom to develop and deploy open source software solutions. Samba is a software solution that epitomizes freedom of choice in network interoperability for Microsoft Windows clients.

  • Getting Ready for Samba4
    Getting Ready for Samba4 Samba Team member Andrew Bartlett explores the world of Samba4, its development status, what you can (and can’t) do with Samba4, and — most importantly– when you can expect to start using Samba4 in a production environment. Andrew Bartlett Thursday, April 3rd, 2008 Ever wanted to run an Active Directory Domain Controller on your Linux server? Did you run a Samba 3.0 DC, but had to move to Active Directory, or worried you might need to? Interested in the leading edge of Samba development, and wondering what the preceding questions mean? Without Samba, Linux, Windows and Macintosh computers could not share files and printers with each other, and networks of windows computers could only use Microsoft’s products to implement consistent user names and passwords across an organisation, something known as domain control. Since Samba was last covered by Linux Magazine in 2002, it seems the whole world has changed. Yet for members of the Samba Team the task remains to provide the Free Software community with a solid implementation of the Common Internet File System (CIFS) protocol, and with that a bridge into the Windows world. It is in that pursuit of interoperability that the Samba Team has continued, soon (at the time of writing) releasing version 3.2.0 of Samba, and alpha releases of Samba4. But Samba4 is more than just a new version of Samba, and more akin to a new development effort. Largely rewritten to handle the problems of interacting with modern versions of Microsoft’s Windows suite, Samba4 has been a storehouse of testing and innovation.

  • Evolving an Efficient and Effective Off-The-Shelf Computing Infrastructure for Schools in Rural Areas of South Africa
    Evolving an efficient and effective off-the-shelf computing infrastructure for schools in rural areas of South Africa A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy of Rhodes University by Ingrid Giselle Sieborger February 2017 Abstract Upliftment of rural areas and poverty alleviation are priorities for development in South Africa. Information and knowledge are key strategic resources for social and economic development and ICTs act as tools to support them, enabling innovative and more cost effective approaches. In order for ICT interventions to be possible, infrastructure has to be deployed. For the deployment to be effective and sustainable, the local community needs to be involved in shaping and supporting it. This study describes the technical work done in the Siyakhula Living Lab (SLL), a long-term ICT4D experiment in the Mbashe Municipality, with a focus on the deployment of ICT infrastructure in schools, for teaching and learning but also for use by the communities surrounding the schools. As a result of this work, computing infrastructure was deployed, in various phases, in 17 schools in the area and a “broadband island” connecting them was created. The dissertation reports on the initial deployment phases, discussing theoretical underpinnings and policies for using technology in education as well various computing and networking technologies and associated policies available and appropriate for use in rural South African schools. This information forms the backdrop of a survey conducted with teachers from six schools in the SLL, together with experimental work towards the provision of an evolved, efficient and effective off-the-shelf computing infrastructure in selected schools, in order to attempt to address the shortcomings of the computing infrastructure deployed initially in the SLL.
