Users and Groups module problem

[yokobr]

Hi guys, i'm getting this error

Trace
root command /etc/init.d/slapd start failed.
Error output:
Command output: 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 (e.g. /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 -h 'ldap:/// ldapi:/// ldaps:///' -g openldap -u openldap -F /etc/ldap/slapd.d/
.

Which version of Zentyal are you using? Is this a fresh install? Or did you installed and then removed some modules?
