Pre --- Install slapd and ldap-utils: sudo aptitude install slapd ldap-utils It will ask for eg. domain, password. If your domain is `example.net`, your basedn will be `dc=example,dc=net`. If you want to use an other basedn, for example `o=example,c=de`, debian/ubuntu will not provide any way to do that. Thats because while these steps your database will be lost and you can choose your basedn. Add your basedn to file `basedn`: echo dc=example,dc=net > basedn Init ---- Usefull defaults for security (better Passwordhashes): ldapmodify -H ldapi:// -Y EXTERNAL -f 10.acls.ldif ldapmodify -H ldapi:// -Y EXTERNAL -f 20.passwordhash.ldif BaseDN ------ These steps will erase your database. If you do not want to change your BaseDN, skip this step. The next step will print your new password on STDERR, so note it. You can change it any time. ./00.suffix.ldif.sh | sudo ldapmodify -H ldapi:// -Y external ./30.root.ldif.sh | sudo -u openldap -i slapadd -vb `cat basedn` Clientconfig ------------ Some lines should be added to `/etc/ldap/ldap.conf`. These would set defaults, so you could omit `-H ldapi://` and `-b $DN`. cat >> /etc/ldap/ldap.conf <
