Samba-LDAP on Debian

Software to install

slapd

apt-get install slapd

choose admin password

dpkg-reconfigure slapd

Go with the defaults

libpam-ldap

apt-get install libpam-ldap

Go with defaults, except for dc values. For Root login account use cn=admin instead of cn=manager.

libnss-ldap

apt-get install libnss-ldap

Go with defaults, except for dc values. For Root login account use cn=admin instead of cn=manager. Fix the base dc= line in /etc/libnss_ldap.conf.

Update /etc/nsswitch.conf

passwd: compat ldap
group: compat ldap

smbldap-tools

apt-get install smbldap-tools

BUGS

• libpam-ldap
  • debconf should be able to provide/suggest already used dc values like slapd debconf does
  • Root login account should be cn=admin?
• libnss-ldap
  • debconf should be able to provide/suggest already used dc values like slapd debconf does
  • in fact it should use same config as libpam-ldap or at least look at it
  • debconf sets base dc=padl,dc=com
• smbldap-tools
  • README.Debian mentions 3. Optionally add indexes to optimize SAMBA access. This is not optional, leaving it out causes smbldap-populate to fail miserably.
  • README.Debian tells to run net getlocalsid after changing samba config. This is wrong, since at that point the command will fail untill evertything is configured and working. This should be a job for debconf anyway.
