  29  * Parameters used as input for the LDAP {@code CertStore} algorithm.
  30  * <p>
  31  * This class is used to provide necessary configuration parameters (server
  32  * name and port number) to implementations of the LDAP {@code CertStore}
  33  * algorithm. However, if you are retrieving certificates or CRLs from
  34  * an ldap URI as specified by RFC 5280, use the
  35  * {@link java.security.cert.URICertStoreParameters URICertStoreParameters}
  36  * instead as the URI may contain additional information such as the
  37  * distinguished name that will help the LDAP CertStore find the specific
  38  * certificates and CRLs.
  39  * <p>
  40  * <b>Concurrent Access</b>
  41  * <p>
  42  * Unless otherwise specified, the methods defined in this class are not
  43  * thread-safe. Multiple threads that need to access a single
  44  * object concurrently should synchronize amongst themselves and
  45  * provide the necessary locking. Multiple threads each manipulating
  46  * separate objects need not synchronize.
