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 Safeguard Authentication Services to reload configuration settings by restarting the Safeguard Authentication Services services.

Restarting services

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

Note: Due to library changes between the Safeguard Authentication Services 4.1 and 4.2, the system may need to be rebooted before all processes load the new libraries.

Automatically generating Posix user identities

When user identity information is not stored centrally within Active Directory, it is possible for Active Directory users to have Posix identity attributes automatically generated for them when interacting with Unix hosts, allowing the user to authenticate with an Active Directory password.

This is convenient in situations where you can not utilize enterprise user and group identification from Active Directory. For example, when you do not have sufficient rights to modify User identity objects, or are unable to create the Safeguard Authentication Services Application Configuration object, you can configure Safeguard Authentication Services to auto-generate Posix identity attributes on the Unix host for Active Directory users.

The following attributes are auto-generated:

  • UID Number: This attribute is derived from a hash of the Active Directory Users Globally Unique Identifier (GUID).
  • GID Number: This attribute is derived from the hash of the Active Directory Group GUID that is assigned as the Windows Primary Group object.
  • Gecos: The gecos field is populated by the users CN, but is configurable by using the [vasd] realname-attr vas.conf setting.
  • Unix Home Directory: This attribute is a concatenation of the per-machine configurable home directory base option, [vasd] autogen-posix-homedir-base, and the users sAMAccountName value.
  • Login Shell: This attribute is set by the per-machine [vasd] autogen-posix-default-shell configuration option.

The generated attributes are stored locally on each Unix host and remain in effect until manually removed by the system administrator.
