To return all attributes from LDAP using ldapsearch you can use both “*” for user and “+” for operational attributes
ldapsearch -LLL -H "ldaps://url:1636" -D "cn=Directory Manager" -w $LDP -b "ou=entity,dc=domain,dc=com" -s sub "(&(attr_filter1=SOMETHING)(attr_filter2=ELSE))" "*" "+"
You would like to do a search for a specific LDAP attribute (ie email) using a file (emails.txt) with the list of emails you want to search for.
After exporting the password (LDP) you can use the following to do the search and output the results into a file (search_results.txt)
ldapsearch -LLL _H "ldaps://ldap_url:port" -D "cn=User_name" -w $LDP -b "ou=ou_name,dc=dc_name,dc=domain_name" -s sub -f emails.txt "(mail_attribute=%s)" uid mail_attribute other_attribute > search_results.txtProblem
You need to install OpenLDAP for testing the authentication against LDAP, but the command line utility ldapsearch is not installed in your system.
Solution
You would need to install Mandriva’s openldap-clients package that includes the ldapsearch:
sudo urpmi openldap-clients
