Hi thanks I understand i will have to start from scratch for certificate .. but few explanation i need My ldapserver host name is : ldap-2.fosiul.lan and I just cn="Directory Manager" so according to those info.. what shall i put in , dc=directory ??? and cn=directory.example.com" ??? My server hostname or "Directory Manager" # certutil -S -n "CA certificate" -s "cn=CA cert,dc=directory,dc=example,dc=com" -2 -x -t "CT,," -m 1000 -v 720 -d . -k rsa Make sure you say yes to "Is this a CA certificate [y/N]?" and everything else will be default. Next we create your server cert. Make sure your cn is your FQDN of this server. # certutil -S -n "directory-Server-Cert" -s "cn=directory.example.com" -c "CA certificate" -t "u,u,u" -m 1001 -v 720 -d . -k rsa Thanks for your help . Really appreciate .. -- 389 users mailing list 389-users@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/389-users
