Administering LDAP on the MSS

The LDAP (Lightweight Directory Access Protocol) directory is used as the primary storage location for Message Storage Server (MSS) subscriber names, email addresses, extensions, and other data.

There are two types of LAN access to the LDAP directory data:

• Private LAN: Private LAN access to the LDAP directory is always enabled on the MSS. The Messaging Application Server (MAS) uses the private LAN to access the LDAP directory information on the MSS. You cannot enable or disable this type of access.
• Public LAN access: You can enable or disable public LAN access to the MSS LDAP directory. You must enable public LAN access to the directory if:
  • Your subscribers will be using the MSS in conjunction with Avaya and Standards-based email client applications, such as Microsoft Outlook and Express, or they will be using "by name" addressing.
  • If you are using subscriber management products such as Mailbox Manager, Avaya's ProVision software, Avaya Speech Access, Avaya Site Administration, or a Directory Enabled Management (DEM) server.

  Email client applications have only read permissions to a limited amount of directory data while products such as Mailbox Manger have read/write permissions to the directory data.

For additional information about administering LDAP on the MSS, see the following:

• Administering LDAP ports
• Accessing the LDAP address directory
• Checking the Alarm log for LDAP directory alarms
• You must add a trusted server to the MSS for each client server (such as Mailbox Manager) to which you want to provide permission to write data to the LDAP directory on the MSS.

Before your subscribers can use "by name" addressing, you must first administer and test Email (Internet Messaging). For more information, see Email (Internet Messaging).
