Hello again:

I copied the certificates in slapd.con:
TLSCipherSuite HIGH: MEDIUM: + sslv2: RSA
TLSCACertificateFile / etc / ldap / slapd-certs / cacert.pem
TLSCertificateFile / etc / ldap / slapd-certs / servercrt.pem
TLSCertificateKeyFile / etc / ldap / slapd-certs / serverkey.pem

and also writes:

SLAPD_SERVICES = "ldap: / / / LDAPS :///"

And start giving me the following error:
root @ mario-desktop: / etc / gulCA # / etc / init.d / slapd start
Starting OpenLDAP: slapd - failed.
The operation failed but no output was produced. For hints on what went
wrong please refer to the system's logfiles (eg / var / log / syslog) or
try running the daemon in Debug mode like via "slapd-d 16383" (warning:
this will create copious output).

Below, you can find the command line options used by this script to
run slapd. Do not forget to specify those options if you
want to look to debugging output:
   slapd-g openldap-u openldap-f / etc / ldap / slapd.conf

Deputy my folder

Thank you very much it is very important
