Oracle Internet Directory Utility class

/* * This class is a usage of the User/ Group class in oracle.ldap.util package * found in ldapjclnt11.jar. This can define a user/ Group using DN, GUID, or * a simple name representing the user. The following methods are exercised * in this sample program: * * - OIDUtils.authenticateUser() - to authenticate a user with the appropriate * credentials * - OIDUtils.createUser() - to create the user * - OIDUtils.createGroup() - to create the Group * - OIDUtils.addUsertoGroup() - to add the user in Group * - OIDUtils.upadteUsers() - to update the user * - OIDUtils.upadteGroups() - to update the Group * */ package utils; /** * * @author ryarakaraju Verion 1.0 */ import java.util.HashMap; import java.util.Map; import oracle.ldap.util.jndi.*; import javax.naming.*; import javax.naming.directory.*; import oracle.ldap.util.UtilException; public class OIDUtils { /* createUser(String[]) will create user in OID. this reuires context value to make a conection with OID.
