Chapter 25 Membership Authentication Attributes

The Membership Authentication attributes are organization attributes. The values applied to them under Service Configuration become the default values for the Membership Authentication template. The service template needs to be created after registering the service for the organization. The default values can be changed after registration by the organization’s administrator. Organization attributes are not inherited by entries in the subtrees of the organization. The Membership Authentication attributes are:

Minimum Password Length

This field specifies the minimum number of characters required for a password set during self-registration. The default value is 8.

If this value is changed, it should also be changed in the registration and error text in the following file:

Default User Roles

This field specifies the roles assigned to new users whose profiles are created through self-registration. There is no default value. The administrator must specify the DNs of the roles that will be assigned to the new user.



Note	The role specified must be under the organization for which authentication is being configured. Only the roles that can be assigned to the user will be added during self-registration. All other DNs will be ignored. The role can be either an Access Manager role or an LDAP role, but filtered roles are not accepted.

User Status After Registration

This menu specifies whether services are immediately made available to a user who has self-registered. The default value is Active and services are available to the new user. By selecting Inactive, the administrator chooses to make no services available to a new user.

Primary LDAP Server

This field specifies the host name and port number of the primary LDAP server specified during Access Manager installation. This is the first server contacted for LDAP authentication. The format is hostname:port. (If there is no port number, assume 389.).

If you have Access Manager deployed with multiple domains, you can specify the communication link between specific instances of Access Manager and Directory Server in the following format (multiple entries must be prefixed by the local server name):

For example, if you have two Access Managers deployed in different locations (L1-machine1-IS and L2- machine2-IS) communicating with different instances of Access Manager (L1-machine1-DS and L2-machine2-DS), it would look the following:

L1-machine1-IS.example.com|L1-machine1-DS.example.com:389 L2-machine2-IS.example.com|L2-machine2-DS.example.com:389

Secondary LDAP Server

This field specifies the host name and port number of a secondary LDAP server available to the Access Manager platform. If the primary LDAP server does not respond to a request for authentication, this server would then be contacted. If the primary server is up, Access Manager will switch back to the primary server. The format is also hostname:port. Multiple entries must be prefixed by the local server name.



Caution	When authenticating users from a Directory Server that is remote from the Access Manager enterprise, it is important that both the Primary and Secondary LDAP Server Ports have values. The value for one Directory Server location can be used for both fields.

DN to Start User Search

This field specifies the DN of the node where the search for a user would start. (For performance reasons, this DN should be as specific as possible.) The default value is the root of the directory tree. Any valid DN will be recognized. If OBJECT is selected in the Search Scope attribute, the DN should specify one level above the level in which the profile exists.

If you use multiple entries, the entries must be prefixed by the local server name.The format is as follows:

DN for Root User Bind

This field specifies the DN of the user that will be used to bind to the Directory Server specified in the Primary LDAP Server and Port field as administrator. The authentication service needs to bind as this DN in order to search for a matching user DN based on the user login ID. The default is amldapuser. Any valid DN will be recognized.

Password for Root User Bind

This field carries the password for the administrator profile specified in the DN for Root User Bind field. There is no default value. Only the administrator’s valid LDAP password will be recognized.

Password for Root User Bind (Confirm)

LDAP Attribute Used to Retrieve User Profile

This field specifies the attribute used for the naming convention of user entries. By default, Access Manager assumes that user entries are identified by the uid attribute. If your Directory Server uses a different attribute (such as givenname) specify the attribute name in this field.

LDAP Attributes Used to Search for a User to be Authenticated

This field lists the attributes to be used to form the search filter for a user that is to be authenticated, and allows the user to authenticate with more than one attribute in the user’s entry. For example, if this field is set to uid, employeenumber and mail, the user could authenticate with any of these names.

User Search Filter

This field specifies an attribute to be used to find the user under the DN to Start User Search field. It works with the User Naming Attribute. There is no default value. Any valid user entry attribute will be recognized.

Search Scope

This menu indicates the number of levels in the Directory Server that will be searched for a matching user profile. The search begins from the node specified in the attribute DN to Start User Search. The default value is SUBTREE. One of the following choices can be selected from the list:

OBJECT — Searches only the specified node

ONELEVEL — Searches at the level of the specified node and one level down

SUBTREE — Search all entries at and below the specified node

Enable SSL Access to LDAP Server

This option enables SSL access to the Directory Server specified in the Primary and Secondary LDAP Server and Port field. By default, the box is not checked and the SSL protocol will not be used to access the Directory Server.

If the LDAP Server is running with SSL enabled (LDAPS), you must make sure that Access Manager is configured with proper SSL trusted certificates so that AM could connect to Directory server over LDAPS protocol

Return User DN To Authenticate

When the Access Manager directory is the same as the directory configured for LDAP, this option may be enabled. If enabled, this option allows the LDAP authentication module to return the DN instead of the userId, and no search is necessary. Normally, an authentication module returns only the userId, and the authentication service searches for the user in the local Access Manager LDAP. If an external LDAP directory is used, this option is typically not enabled.

Authentication Level

The authentication level is set separately for each method of authentication. The value indicates how much to trust an authentication. Once a user has authenticated, this value is stored in the SSO token for the session. When the SSO token is presented to an application the user wants to access, the application uses the stored value to determine whether the level is sufficient to grant the user access. If the authentication level stored in an SSO token does not meet the minimum value required, the application can prompt the user to authenticate again through a service with a higher authentication level. The default value is 0.



Note	If no authentication level is specified, the SSO token stores the value specified in the Core Authentication attribute Default Auth Level. See “Default Authentication Level” on page 306 for details.
