I am following the tutorial at https://help.ubuntu.com/8.10/serverguide/C/openldap-server.html. Everything worked until... Command: sudo /etc/init.d/slapd restart Output: Stopping OpenLDAP: slapd. 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://127.0.0.1:389/ ldaps:/// ldapi:///' -g openldap -u openldap -F /etc/ldap/slapd.d/ Command: slapd -d 16383 Output: @(#) $OpenLDAP: slapd 2.4.11 (Nov  8 2008 09:42:18) $         buildd@palmer:/build/buildd/openldap-2.4.11/debian/build/servers/slapd ldap_pvt_gethostbyname_a: host=MORPHEUS.matrix.corp, r=0 daemon_init: <null> daemon_init: listen on ldap:/// daemon_init: 1 listeners to open... ldap_url_parse_ext(ldap:///) daemon: bind(7) failed errno=13 (Permission denied) daemon: bind(7) failed errno=13 (Permission denied) slap_open_listener: failed on ldap:/// slapd stopped. connections_destroy: nothing to destroy.
