using ldapsearch to return only a value

linux, openldap

Solution

Here's how you query your ldap server.

HOSTNAME=<your ladap hostname>
USERNAME=<your ldap username>
PASSWORD=<your ldap username's password>
SEARCHBASE=<your ldap's search base DN>
QUERYSTRING=test1
PORT=<your ldap port>

ldapsearch -LLL -h ${HOSTNAME} -p $PORT -D cn=${USERNAME} -w ${PASSWORD} -b "${SEARCHBASE}" "(id=${QUERYSTRING})" uri | sed -n 's/^[ \t]*uri:[ \t]*\(.*\)/\1/p'

The option `-LLL` will not print ldap comments on output. Your ldap may require `-x` (simple authentication) if it doesn't support `SASL`.

Problem

using an OPENLDAP server i want to retrieve informations from it with ldapsearch. I created a custom class called iduriclass, this class is used to store an id and an uri. in my ldapsearch command i want it to return only the uri for a specified id. EXAMPLE : the directory contain now two entries `id=test uri=server.com/test` and `id=test2 uri=server.com/test2` Trying it i get an ldif file that contains all uris in the server I want to have an ldapsearch command that takes test as argument and returns only a value that is : `server.com/test`
