Servei de Directori amb OpenLDAP [6]: Certificats en Debian 7 "Wheezy"

El procediment d'instal·lació i configuració del bufetada, així com la resta del que indiquen els dos articles anteriors, amb l'excepció de la generació dels certificats, és vàlid per al Wheezy.

Emprarem l'estil de la consola majoritàriament ja que es tracta d'ordres de consola. Deixem totes les sortides perquè guanyem en claredat i puguem llegir amb deteniment quins missatges ens torna el procés, que d'una altra manera gairebé mai llegim detingudament.

La major cura que hem de tenir és quan ens preguntin:

Common Name (eg server FQDN or YOUR name) []:mildap.amics.cu

i hem d'escriure el FQDN del nostre servidor LDAP, que en el nostre cas és mildap.amics.cu. Si no ho feu, no funcionarà correctament el certificat.

Per obtenir els certificats, seguirem el procediment següent:

:~# mkdir /root/myca
:~# cd /root/myca/
:~/myca# /usr/lib/ssl/misc/CA.sh -newca
