ldapsearch Examples

In the next set of examples, the following assumptions are made:

Returning All Entries

Given the previous information, the following call will return all entries in the directory:

ldapsearch -h myServer -p 5201 -D cn=admin,cn=Administrators,cn=config
 -b "dc=example,dc=com" -s sub "(objectclass=*)"

"(objectclass=*)" is a search filter that matches any entry in the directory.

Specifying Search Filters on the Command Line

You can specify a search filter directly on the command line. If you do this, be sure to enclose your filter in quotation marks (“filter”). Also, do not specify the -f option.

For example:

ldapsearch -h myServer -p 5201 -D cn=admin,cn=Administrators,cn=config -w -
 -b "dc=example,dc=com" "(cn=Charlene Daniels)"

Searching the Root DSE Entry

The root DSE is a special entry that contains information related to the current server instance, such as a list of supported suffixes, available authentication mechanisms, and so forth. You can search this entry by supplying a search base of “”. You must also specify a search scope of base and a filter of "(objectclass=*)".

For example:

ldapsearch -h myServer -p 5201 -D cn=admin,cn=Administrators,cn=config -w -
 -b "" -s base "(objectclass=*)"

Searching the Schema Entry

Directory Server stores all directory server schema in the special cn=schema entry. This entry contains information on every object class and attribute defined for your directory server.

You can examine the contents of this entry as follows:

ldapsearch -h myServer -p 5201 -D cn=admin,cn=Administrators,cn=config
 -b "cn=schema" -s base "(objectclass=*)"

Note –

For strict compliance, the location of the schema subentry for a given entry is specified by the subschemaSubentry operational attribute. In this version of Directory Server, the value of this attribute is always cn=schema.


To make searching easier, you can set your search base using the LDAP_BASEDN environment variable. Doing this allows you to skip specifying the search base with the -b option (for information on how to set environment variables, see the documentation for your operating system).

Typically, you set LDAP_BASEDN to your directory’s suffix value. Since your directory suffix is equal to the root, or topmost, entry in your directory, this causes all searches to begin from your directory’s root entry.

For example, if you have set LDAP_BASEDN to dc=example,dc=com, you can search for (cn=Charlene Daniels) in your directory using the following command-line call:

ldapsearch -h myServer -p 5201 -D cn=admin,cn=Administrators,cn=config -w -
 "(cn=Charlene Daniels)"

In this example, the default scope of sub is used because the -s option was not used to specify the scope.

Displaying Subsets of Attributes

The ldapsearch command returns all search results in LDIF format. By default, ldapsearch returns the entry’s distinguished name and all of the attributes that you are allowed to read. You can set up the directory access control such that you are allowed to read only a subset of the attributes on any given directory entry.) Only operational attributes are not returned. If you want operational attributes returned as a result of a search operation, you must explicitly specify them in the search command. For more information on operational attributes, refer to the TODO: No more AdminServerAdminGuide.

Suppose you do not want to see all of the attributes returned in the search results. You can limit the returned attributes to just a few specific attributes by specifying the ones you want on the command line immediately after the search filter. For example, to show the cn and sn attributes for every entry in the directory, use the following command:

ldapsearch -h myServer -p 5201 -D cn=admin,cn=Administrators,cn=config -w -
 "(objectclass=*)" sn cn

This example assumes you set your search base with LDAP_BASEDN.

Searching Multi-Valued Attributes

During a search, Directory Server does not necessarily return multi-valued attributes in sorted order. For example, suppose you want to search for configuration attributes on cn=config requiring that the server be restarted before changes take effect.

ldapsearch -h myServer -p 5201 -D cn=admin,cn=Administrators,cn=config -w -
 -b cn=config "(objectclass=*)" nsslapd-requiresrestart

The following result is returned:

dn: cn=config
nsslapd-requiresrestart: cn=config:nsslapd-port
nsslapd-requiresrestart: cn=config:nsslapd-secureport
nsslapd-requiresrestart: cn=config:nsslapd-plugin
nsslapd-requiresrestart: cn=config:nsslapd-changelogdir
nsslapd-requiresrestart: cn=config:nsslapd-changelogsuffix
nsslapd-requiresrestart: cn=config:nsslapd-changelogmaxentries
nsslapd-requiresrestart: cn=config:nsslapd-changelogmaxage
nsslapd-requiresrestart: cn=config:nsslapd-db-locks
nsslapd-requiresrestart: cn=config:nsslapd-return-exact-case
nsslapd-requiresrestart: cn=config,cn=ldbm database,cn=plugins,
nsslapd-requiresrestart: cn=config,cn=ldbm database,cn=plugins,
nsslapd-requiresrestart: cn=config,cn=ldbm database,cn=plugins,
nsslapd-requiresrestart: cn=config,cn=ldbm database,cn=plugins,
nsslapd-requiresrestart: cn=encryption,cn=config:nssslsessiontimeout
nsslapd-requiresrestart: cn=encryption,cn=config:nssslclientauth
nsslapd-requiresrestart: cn=encryption,cn=config:nssslserverauth
nsslapd-requiresrestart: cn=encryption,cn=config:nsssl2
nsslapd-requiresrestart: cn=encryption,cn=config:nsssl3

As shown here, the nsslapd-requiresrestart attribute takes multiple values. These values are not, however, in sorted order. If you develop an application that requires multi-valued attributes in sorted order, make sure that your application performs the sort.

Using Client Authentication When Searching

This example shows user cdaniels searching the directory using client authentication:

ldapsearch -h myServer -p 636 -b "dc=example,dc=com"
  -N  "cdanielsscertname" -Z -W certdbpassword
  -P /home/cdaniels/certdb/cert.db "(givenname=Richard)"
