Enabling Secure IMAP Authentication

Your IMAP mail service can protect users’ passwords by requiring that connections use

a secure method of authentication. You can choose CRAM MD-5, or Kerberos v5

authentication. When a user connects with secure authentication, the user’s mail client

software encrypts the user’s password before sending it to your IMAP service. Make

sure that your users’ email applications and user accounts support the method of

authentication you choose.

If you configure your mail service to require CRAM MD-5, mail users’ accounts must be

set to use a Mac OS X Server Password Server that has CRAM MD-5 enabled. For

information, see the Open Directory administration guide.

Before enabling Kerberos authentication for incoming mail service, you must integrate

Mac OS X with a Kerberos server. If you’re using Mac OS X Server for Kerberos

authentication, this is already done for you. For instructions, see the Open Directory

administration guide for more information.

If you want to require any of these authentication methods, enable only one method.

To set secure IMAP authentication:

1 In Server Admin, select Mail in the Computers & Services pane.

2 Click Settings.

3 Select the Advanced tab.

4 Select Security.

5 Select CRAM MD-5 or Kerberos (as desired) in the IMAP section.

6 Click Save.
