Step 4: Select the User Database

The next screen (Database Options) asks you to select the user database option you prefer. See Step 3: Choose the Type of User Database in the "Planning Your Installation" section. Select from the following database options:

• Windows NT User Database - IMail Server creates a user mail account for each user listed in the NT Database. Note that you will need to use the Windows NT User Manager to add or delete users. You cannot add or delete users from the NT database using IMail Administrator.
• IMail User Database - User IDs and passwords for mail accounts are created using IMail Administrator and stored in a database on the IMail server.
• External Database (ODBC compliant) - IMail uses an external database to register and authenticate users. Users that you add and delete using IMail Administrator will be added to and deleted from that external database and vice versa.

  Selecting External Database, you must specify the ODBC System DSN for the database, along with the user ID and password to log on to the database server. IMAILSECDB is the default name that the IMail ODBC link uses. For example, for the System DSN, you would enter: imailsecdb;UID=imailuser;PWD=password

  Note: If a domain uses an external database, the Internet guest account (IUSR_<computer name>) must have full permissions set for the directory in which the database exists. For example, if the external database resides in c:\somewhere, then the Internet Guest Account must have full permissions to that directory.

• Active Directory Database - IMail Server will create a user mail account for each Active Directory user listed from the Root Directory Service Entry (DSE). You can change this default in the Web Administrator under Domain Properties > User Database Type > NT/AD Database (Drop down List) > Naming Context. You cannot add or delete users using the IMail Administrator with Active Directory.

  Note: IMail Server is now designed to not display built-in Active Directory users. The word "built-in" must be added to the front of the full description under Active Directory user properties.
