Note: For maximum security and performance, before you begin the installation, make sure that you have the latest patches for your operating system version. One Identity recommends that you run the Preflight utility to check for supported operating systems and correct operating system patches.
Safeguard Authentication Services includes the following Unix components.
| Unix component | Description |
|---|---|
|
vasd |
The Safeguard Authentication Services agent background process that manages the persistent cache of Active Directory information used by the other Safeguard Authentication Services components. vasd is installed as a system service. You can start and stop vasd using the standard service start/stop mechanism for your platform. vasd is installed by the vasclnt package. |
|
vastool |
The Safeguard Authentication Services command line administration utility that allows you to join a Unix host to an Active Directory Domain; access and modify information about users, groups, and computers in Active Directory; and configure the Safeguard Authentication Services components. vastool is installed at /opt/quest/bin/vastool. vastool is installed by the vasclnt package. |
|
vgptool |
A command line utility that allows you to manage the application of Group Policy settings to Safeguard Authentication Services clients. vgptool is installed at /opt/quest/bin/vgptool. vgptool is installed by the vasgp package. |
|
oat (Ownership Alignment Tool) |
A command line utility that allows you to modify file ownership on local Unix hosts to match user accounts in Active Directory. oat is installed at /opt/quest/libexec/oat/oat. oat is installed by the vasclnt package. |
|
LDAP proxy |
A background process that secures the authentication channel for applications using LDAP bind to authenticate users without introducing the overhead of configuring secure LDAP (LDAPS). The LDAP proxy is installed by the vasproxy package. |
|
NIS proxy |
A background process that acts as a NIS server which can provide backwards compatibility with existing NIS infrastructure. The NIS proxy is installed by the vasyp package. |
|
SDK package |
The vasdev package, the Safeguard Authentication Services programming API. |
The following table details the permissions required for full Safeguard Authentication Services functionality.
| Function | Active Directory permissions | Local client permissions |
|---|---|---|
| Safeguard Authentication Services Application Configuration: creation | Location in Active Directory with Create Container Object rights | N/A |
Safeguard Authentication Services Application Configuration: changes
|
Update permission to the containers created above (no particular permissions if you are the one who created it) | N/A |
| Schema optimization | Schema Administrator rights | N/A |
| Display Specifier Registration | Enterprise Administrator rights | N/A |
| Editing Users | Administrator rights | N/A |
|

| Unix Account Import Wizard | Administrator rights (you are creating new accounts) | N/A |
| Logging Options | Write permissions to the file system folder where you want to create the logs | N/A |
| vasd daemon |
The client computer object is expected to have read access to user and group attributes, which is the default. In order for Safeguard Authentication Services to update the host object operating system attributes automatically, set the following rights for "SELF" on the client computer object: Write Operating System, Write operatingSystemHotfix, and Write operatingSystemServicePack. |
