# LDAP Authentication Provider: Configuration: Common

Configuration Options Related Tasks Related Topics

Use this page to define the general configuration of this LDAP Authentication provider.

Authentication is the process whereby the identity of users or system processes are proved or verified. Authentication also involves remembering, transporting, and making identity information available to various components of a system when that information is needed.

By default, the WebLogic Authentication provider is configured in the default security realm (myrealm). The WebLogic Authentication provider allows you to edit, list, and manage users, groups, and group membership. User and group information is stored in the embedded LDAP server.

The Control Flag attribute is the Java Authentication and Authorization Service (JAAS) control flag that determines how the LoginModule for the WebLogic Authentication provider is used in the login sequence.

You can use a custom Authentication provider instead of the WebLogic Authentication provider. For a custom Authentication provider to be available in the WebLogic Server Administration Console, the MBean JAR file for the provider must be in the `WL_HOME\lib\mbeantypes` directory.

#### Configuration Options

Name | Description
--- | ---
Name | The name of the Java class used to load the LDAP Authentication provider. MBean Attribute: `LDAPAuthenticatorMBean.ProviderClassName` Changes take effect after you redeploy the module or restart the server.
Description | A short description of the LDAP Authentication provider. MBean Attribute: `LDAPAuthenticatorMBean.Description` Changes take effect after you redeploy the module or restart the server.
Version | The version number of the LDAP Authentication provider. MBean Attribute: `LDAPAuthenticatorMBean.Version` Changes take effect after you redeploy the module or restart the server.
Control Flag | Returns how the login sequence uses the Authentication provider. A `REQUIRED` value specifies this LoginModule must succeed. Even if it fails, authentication proceeds down the list of LoginModules for the configured Authentication providers. This setting is the default. A `REQUISITE` value specifies this LoginModule must succeed. If other Authentication providers are configured and this LoginModule succeeds, authentication proceeds down the list of LoginModules. Otherwise, control is return to the application. A `SUFFICIENT` value specifies this LoginModule need not succeed. If it does succeed, return control to the application. If it fails and other Authentication providers are configured, authentication proceeds down the LoginModule list. An `OPTIONAL` value specifies this LoginModule need not succeed. Whether it succeeds or fails, authentication proceeds down the LoginModule list. MBean Attribute: `LDAPAuthenticatorMBean.ControlFlag` Changes take effect after you redeploy the module or restart the server.
