The UnboundID LDAP SDK for Java is a fast, comprehensive, and easy-to-use
Java API for communicating with LDAP directory servers and performing
related tasks like reading and writing LDIF, encoding and decoding data
using base64 and ASN.1 BER, and performing secure communication. This
package contains the Standard Edition of the LDAP SDK, which is a
complete, general-purpose library for communicating with LDAPv3 directory
servers.

/**
* This class provides an implementation of the password policy response control
* as described in draft-behera-ldap-password-policy. It may be used to provide
* information related to a user's password policy. It may include at most one
* warning from the set of {@link PasswordPolicyWarningType} values and at most
* one error from the set of {@link PasswordPolicyErrorType} values. See the
* documentation for those classes for more information on the information that
* may be included. See the {@link PasswordPolicyRequestControl} documentation
* for an example that demonstrates the use of the password policy request and
* response controls.
*
*
* NOTE: This class, and other classes within the
* {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
* supported for use against Ping Identity, UnboundID, and
* Nokia/Alcatel-Lucent 8661 server products. These classes provide support
* for proprietary functionality or for external specifications that are not
* considered stable or mature enough to be guaranteed to work in an
* interoperable way with other types of LDAP servers.
*
*
* The control has an OID of 1.3.6.1.4.1.42.2.27.8.5.1 and a criticality of
* false. It must have a value with the following encoding:
*
* PasswordPolicyResponseValue ::= SEQUENCE {
* warning [0] CHOICE {
* timeBeforeExpiration [0] INTEGER (0 .. maxInt),
* graceAuthNsRemaining [1] INTEGER (0 .. maxInt) } OPTIONAL,
* error [1] ENUMERATED {
* passwordExpired (0),
* accountLocked (1),
* changeAfterReset (2),
* passwordModNotAllowed (3),
* mustSupplyOldPassword (4),
* insufficientPasswordQuality (5),
* passwordTooShort (6),
* passwordTooYoung (7),
* passwordInHistory (8) } OPTIONAL }
