h3. Install required packages 

<pre>apt-get install samba krb5-config krb5-user winbind libpam-winbind libnss-winbind</pre>

=== Reconfigure krb5-config ===

<pre>dpkg-reconfigure krb5-config</pre>

Answer with the REALM (in case of etb1: ''DOMPEDAGO.ETB1.LAN'')

h3. Test kerberos server

<pre>~# kinit admin (password: eole)

~# klist

Ticket cache: FILE:/tmp/krb5cc_0

Default principal: admin@DOMPEDAGO.ETB1.LAN

Valid starting       Expires              Service principal

20/11/2019 09:33:22  20/11/2019 19:33:22  krbtgt/DOMPEDAGO.ETB1.LAN@DOMPEDAGO.ETB1.LAN

    renew until 21/11/2019 09:33:20</pre>

h3. Configure samba

<pre> mv /etc/samba/smb.conf /etc/samba/smb.conf.initial

 cat > /etc/samba/smb.conf << EOF

 [global]

        workgroup = DOMPEDAGO

        realm = DOMPEDAGO.ETB1.LAN

        netbios name = ubuntu

        security = ADS

        dns forwarder = 10.1.3.11

        idmap config *:range = 2000-2999

        idmap config DOMPEDAGO:backend = rid

        idmap config DOMPEDAGO:range = 10000-999999

   template homedir = /home/adhomes/%U

   template shell = /bin/bash

   winbind use default domain = true

   winbind offline logon = false

   winbind nss info = rfc2307

   winbind enum users = yes

   winbind enum groups = yes

  vfs objects = acl_xattr

  map acl inherit = Yes

  store dos attributes = Yes

EOF</pre>

h3. Join samba domain

<pre>net ads join -U admin

systemctl restart smbd nmbd winbind</pre>

h3. Modify nsswitch configuration

<pre>#/etc/nsswitch.conf

# /etc/nsswitch.conf

#

# Example configuration of GNU Name Service Switch functionality.

# If you have the `glibc-doc-reference' and `info' packages installed, try:

# `info libc "Name Service Switch"' for information about this file.

passwd:         compat winbind systemd ldap

group:          compat winbind systemd ldap

shadow:         compat ldap

gshadow:        files

hosts:          files mdns4_minimal [NOTFOUND=return] dns

networks:       files

protocols:      db files

services:       db files

ethers:         db files

rpc:            db files

netgroup:       nis</pre>

h3. Give it a try:

<code>wbinfo -u</code> should return all local users along domain users <code>wbinfo -g</code> should return all local groups along domain groups

h3. Modify pam configuration

Activate winbind login with:

<pre>pam-auth-update</pre>

Edit /etc/pam.d/common-password to replace winbind line with this one:

<pre>...

password        [success=1 default=ignore]      pam_winbind.so try_first_pass

...</pre>

If you want to activate homedir creation upon login add the following line at the end of /etc/pam.d/common-account:

<pre>session    required    pam_mkhomedir.so    skel=/etc/skel/    umask=0022</pre>

=== Reboot and test ===

You should be able to log in with domains users (admin,prof.6a….)

h3. Install libpam-mount

**This part is not fully fonctionnal for now**

<pre>apt-get install libpam-mount

cat > /etc/security/pam_mount.conf.xml << EOF

<?xml version="1.0" encoding="utf-8" ?>

<!DOCTYPE pam_mount SYSTEM "pam_mount.conf.xml.dtd">

<pam_mount>

    <debug enable="0" />

    <volume user="*" fstype="cifs" server="10.1.3.11" path="%(DOMAIN_USER)" mountpoint="/home/adhomes/%(DOMAIN_USER)" options="sec=ntlmssp,nodev,nosuid,mfsymlinks,nobrl,vers=1.0" />

    <mntoptions allow="nosuid,nodev,loop,encryption,fsck,nonempty,allow_root,allow_other" />

    <mntoptions require="nosuid,nodev" />

    <logout wait="0" hup="no" term="no" kill="no" />

    <mkmountpoint enable="1" remove="true" />

</pam_mount>

EOF
