Troubleshooting LDAP

Healthy:

slapd should be running

If not:

Check /var/log/ldap.log

If database corrupted, use db_recover -h <path-to-database>

<path-to-database> can be /var/lib/ldap, can be found on /etc/openldap/slapd.conf

A sample extract from /etc/openldap/slapd.conf
# The database directory MUST exist prior to running slapd AND
# should only be accessible by the slapd and slap tools.
# Mode 700 recommended.
directory       /var/lib/ldap

Make sure to:
$ chown -R ldap /var/lib/ldap && chgrp -R ldap /var/lib/ldap

If it does not work, check the backup (for instance /var/lib/ldap/backup) against the current database directory
