037 * The class is used to perform privileged operation with
038 * <code>AccessController.doPrivileged()
039 * </code> when using
040 * <code> com.iplanet.am.util.AMPasswordUtil</code> to encrypt passwords. Ths
041 * class implements the interface <code>
042 * PrivilegedAction </code> with a
043 * non-default constructor. This class should be used in order to perform the
044 * privileged operation of
045 * <code> com.iplanet.am.util.AMPasswordUtil.encrypt()</code>.

047 * <PRE>
048 * 
049 * This line of code: String encStr =
050 * com.iplanet.am.util.AMPasswordUtil.encrypt(str); should be replaced with:
051 * String encStr = (String) AccessController.doPrivileged( new
052 * EncryptAction(str)); If this is not done and Java security permissions check
053 * is enabled, then the operation will fail and return a null everytime.
054 * 
055 * Note: Java security permissions check for OpenSSO can be enabled by
056 * setting the property <code>com.sun.identity.security.checkcaller</code> to
057 * true in AMConfig properties file.
