Using map files to map users

Instead of modifying password entries directly, you can map local Unix users to Active Directory accounts using map files.

To configure a user mapping file

  1. Run the following command as root to enable local map files:
    vastool configure vas vas_auth user-map-files /etc/user-map

    Note: This example configures Authentication Services to use /etc/user-map for user mappings. You can specify any filename.

  2. Add user mappings to the map file.

    The format is <local user name>:<sAMAccountName@domain>.

    If you want to map a local user named jdoe to the Active Directory account for johnd@example.com, add the following line to the file:

    jdoe:johnd@example.com

Mapping the root account

You can only map the root account to an Active Directory account using the mapped-root-user setting in vas.conf.

To map the root user to an Active Directory account

  1. Run the following command as root: 
    vastool configure vas vas_auth mapped-root-user Administrator@example.com

Note: If you specify mapped-root-user on AIX you must set VASMU on the system line of the root section in /etc/security/user. Refer to your AIX system documentation for more information.

Enable self enrollment

Self enrollment allows users to map their Unix account to an Active Directory account as they log in to Unix. This mapping occurs as part of the standard PAM login. Users are first prompted for their Unix password. Once authenticated to Unix, they are prompted to authenticate to Active Directory. This process happens on the first log in after you enable self enrollment. Once the self enrollment is complete, the user logs in with his Unix user name and Active Directory password.

To enable self enrollment:

  1. Run the following command as root: 
    vastool configure vas vas_auth enable-self-enrollment true

    Note: All users mapped by the self-enrollment process are stored in the /etc/opt/quest/vas/automatic_mappings file.

  2. Force Authentication Services to reload configuration settings by restarting the Authentication Services services.

Restarting Authentication Services Services

  1. The method for restarting services varies by platform:
    1. To restart Authentication Services on Linux or Solaris, enter:
      /etc/init.d/vasd restart
    2. To restart Authentication Services on HP-UX, enter:
      /sbin/init.d/vasd restart
    3. To restart Authentication Services on AIX, enter:
      stopsrc -s vasd
startsrc -s vasd

Note: Due to library changes between the Authentication Services 3.x and 4.1, One Identity recommends that you restart all long-lived processes that use Authentication Services data to force a reload of the newer libraries. For example, you must restart cron.
