# derby.authentication.ldap.searchAuthDN

Along with derby.authentication.ldap.searchAuthPW, this property indicates how Derby should bind with the LDAP directory server to do searches for user DN (distinguished name). This property specifies the DN; derby.authentication.ldap.searchAuthPW specifies the password to use for the search.

If these two properties are not specified, an anonymous search is performed if it is supported.

For more information about LDAP user authentication, see "LDAP Directory Service" in Chapter 7 of the Derby Developer's Guide.

#### Syntax

    derby.authentication.ldap.searchAuthDn=DN

#### Default

If not specified, an anonymous search is performed if it is supported.

#### Example

    -- system-wide property
    derby.authentication.ldap.searchAuthDn=
        cn=guest,o=ExampleSite.com
    -- database-wide property
    CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY(
        'derby.authentication.ldap.searchAuthDn',
        'cn=guest,o=ExampleSite.com')

#### Dynamic or static

Static. For system-wide properties, you must reboot Derby for the change to take effect. For database-wide properties, you must reboot the database for the change to take effect.
