/**

 * Parameters used as input for the LDAP {@code CertStore} algorithm.

 * <p>

 * This class is used to provide necessary configuration parameters (server

 * name and port number) to implementations of the LDAP {@code CertStore}

 * algorithm. However, if you are retrieving certificates or CRLs from

 * an ldap URI as specified by RFC 5280, use the

 * {@link java.security.cert.URICertStoreParameters URICertStoreParameters}

 * instead as the URI may contain additional information such as the

 * distinguished name that will help the LDAP CertStore find the specific

 * certificates and CRLs.

 * <p>

 * <b>Concurrent Access</b>

 * <p>

 * Unless otherwise specified, the methods defined in this class are not

 * thread-safe. Multiple threads that need to access a single

 * object concurrently should synchronize amongst themselves and

 * provide the necessary locking. Multiple threads each manipulating

 * separate objects need not synchronize.

 *

 * @since       1.4
