AuthType

Use user/password configured on the AuthType authentication server. No logins

allowed if the AuthType server is down or the AuthType authentication fails.

AuthType Down/Local Use local authentication if the AuthType server is down.

AuthType/Local Use local authentication if the AuthType authentication fails.

Local/AuthType Use the AuthType authentication if local authentication fails.

NOTE: The AuthType is Kerberos, LDAP, NIS, RADIUS, SMB, TACACS+ or DSView 3. For the DSView 3

authentication method, the MergePoint SP manager must be managed by the DSView 3 management software;

otherwise, the DSView 3 authentication will fail.

The default authentication service type is Kerberos. If any other authentication method is

selected, additional fields appear on the screen for specifying the information for an

authentication service of the selected method.

When the administrative user configures an authentication server on this page, the server is

available to perform authentication checking for logins to the MergePoint SP manager, if the

MergePoint SP manager is subsequently configured to use that authentication method. See

Configuring an Authentication Method for the MergePoint SP Manager on page 100 for how

the MergePoint SP manager is assigned an authentication method.

Configuring a Kerberos Authentication Server

You need to configure a Kerberos authentication server when the MergePoint SP manager is

configured to use the Kerberos authentication method or any of its variations (Kerberos, Local/

Kerberos, Kerberos/Local or Kerberos Down/Local).

If the Kerberos authentication server (which is also referred to as a Key Distribution Center, or

KDC) has previously been configured in either of the authentication configuration screens, the

fields are filled in with the previously configured values.

NOTE: The Kerberos KDC rejects tickets when the timestamp on an authentication request from a host is not within

the maximum clock skew time specified in the KDC’s hdc.conf file. Therefore, it is essential for the time on the

MergePoint SP manager to be synchronized with the time on the KDC.

To configure a Kerberos authentication server:

1. Make sure entries for the appliance and the Kerberos server exist in the MergePoint SP

manager’s /etc/hosts file.

a. Select the Network - Host Table menu option. The Host Table form appears.
