Class LdapDnsProvider

java.lang.Object
javax.naming.ldap.spi.LdapDnsProvider
public abstract class LdapDnsProvider extends Object
Service-provider class for DNS lookups when performing LDAP operations.

An LDAP DNS provider is a concrete subclass of this class that has a zero-argument constructor. LDAP DNS providers are located using the ServiceLoader facility, as specified by InitialDirectContext. The ServiceLoader is used to create and register implementations of LdapDnsProvider.

An LDAP DNS provider can be used in environments where the default DNS resolution mechanism is not sufficient to accurately pinpoint the correct LDAP servers needed to perform LDAP operations. For example, in an environment containing a mix of ldap and ldaps servers you may want the LdapContext to query ldaps servers only.
