Examples of LDAP URLs

The syntax for LDAP URLs does not include any means for specifying credentials or passwords. Search request initiated through LDAP URLs are unauthenticated (anonymous), unless the LDAP client that supports LDAP URLs provides an authentication mechanism. This section gives examples of LDAP URLs.

Example 12–1 Base Search for an Entry

The following LDAP URL specifies a base search for the entry with the distinguished name dc=example,dc=com.

ldap://ldap.example.com/dc=example,dc=com

• Because no port number is specified, the standard LDAP port number 389 is used.

• Because no attributes are specified, the search returns all attributes.

• Because no search scope is specified, the search is restricted to the base entry dc=example,dc=com.

• Because no filter is specified, the directory uses the default filter objectclass=*.

Example 12–2 Retrieving postalAddress Attribute of an Entry

The following LDAP URL retrieves the postalAddress attribute of the entry with the DN dc=example,dc=com:

ldap://ldap.example.com/dc=example,dc=com?postalAddress

• Because no search scope is specified, the search is restricted to the base entry dc=example,dc=com.

• Because no filter is specified, the directory uses the default filter objectclass=*.

Example 12–3 Retrieving cn and mail Attributes of an Entry

The following LDAP URL retrieves the cn, and mail attributes of the entry for Barbara Jensen.

ldap://ldap.example.com/cn=Barbara%20Jensen,dc=example, dc=com?cn,mail

• Because no search scope is specified, the search is restricted to the base entry cn=Barbara Jensen,dc=example,dc=com.

• Because no filter is specified, the directory uses the default filter objectclass=*.

Example 12–4 Retrieving the Surname Jensen Under dc=example,dc=com

The following LDAP URL specifies a search for entries that have the surname Jensen and are at any level under dc=example,dc=com:

ldap://ldap.example.com/dc=example,dc=com??sub?(sn=Jensen)

• Because no attributes are specified, the search returns all attributes.

• Because the search scope is sub, the search encompasses the base entry dc=example,dc com and entries at all levels under the base entry.

Example 12–5 Retrieving the Object Class for all Entries One Level Under dc=example,dc=com

The following LDAP URL specifies a search for the object class for all entries one level under dc=example,dc=com:

ldap://ldap.example.com/dc=example,dc=com?objectClass?one

• Because the search scope is one, the search encompasses all entries one level under the base entry dc=example,dc=com. The search scope does not include the base entry.

• Because no filter is specified, the directory uses the default filter objectclass=*.
