Safeguard Authentication Services 6.1 - Administration Guide

To restart services, enter:

vastool daemon restart vasd

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.

Once a host has Posix identity attributes generated for an Active Directory user or group, they remain in effect until you manually remove them. This ensures that you take the proper steps when migrating user identities, specifically when you realign the file and directory ownerships to the new UID and GID values.

This section describes how to migrate auto-generated group identities.
