Management Console for Unix requirements

One Identity recommends that you install One Identity Management Console for Unix, a separate One Identity product which provides a mangement console that is a powerful and easy-to-use tool that dramatically simplifies deployment of Authentication Services agents to your clients. The mangement console streamlines the overall management of your Unix, Linux, and Mac OS X hosts by enabling centralized management of local Unix users and groups and providing granular reports on key data and attributes.

Prior to installing Management Console for Unix, ensure your system meets the minimum hardware and software requirements for your platform.

Table 9: Management Console for Unix: Hardware and software requirements
Component Requirements
Supported Windows Platforms

Can be installed on 32-bit or 64-bit editions of the following configurations:

  • Windows XP SP2 (or later)
  • Windows Vista
  • Windows 7
  • Windows 8
  • Windows Server 2003 SP1 (or later)
  • Windows Server 2008
  • Windows Server 2008 R2
  • Windows Server 2012

NOTE: When running Management Console for Unix on Windows Server 2008 R2, functioning as a domain controller, the process must be elevated. As a best practice, One Identity does not recommend that you install or run the Windows components on Active Directory domain controllers. The recommended configuration is to install them on an administrative workstation.

NOTE: The performance of some Active Directory searches may be better on:

  • 64bit: Windows Server 2003 64-bit and above
  • 32bit: Windows Server 2003 SP1 + hotfix* or Windows 2003 SP2 (and above)

    (*Click Microsoft Support to read a Microsoft article entitled, "A hotfix is available that improves the performance of programs that query Active Directory for group memberships in Windows Server 2003".

    To apply this hotfix, you must have Windows Server 2003 Service Pack 1 (SP1) installed. Note: The x64-based versions of Windows Server 2003 already include the fixes and features that are included in Windows Server 2003 SP1. If the computer is running an x64-based version of Windows Server 2003, you do not have to install SP1.

Server Requirements

You can install Management Console for Unix on any platform that has 32-bit Sun JRE (Java Runtime Environment) 1.6.

NOTE: Management Console for Unix is not supported on AIX.

Managed Host Requirements

Click here to view a list of supported Unix, Linux, and Mac OS X platforms that the server can manage; that is, hosts you can add and profile from the mangement console.

NOTE: To use Authentication Services with the mangement console on a Solaris 10 Sparc, you must have Authentication Services 4.0.3.152 or greater.

NOTE: To enable the Management Console for Unix server to interact with the host, you must install both an SSH server (that is, sshd) and an SSH client on each managed host. Both OpenSSH 2.5 (and higher) and Tectia SSH 5.0 (and higher) are supported.

Default memory requirement:

1024 MB

NOTE: See Tune JVM Memory in online help for information about changing the default memory allocation setting in the configuration file.

Supported Web Browsers

The mangement console officially supports the following web browsers:

  • Microsoft Internet Explorer 7, 8, 9, and 10
  • Mozilla Firefox 3 and greater
  • Apple Safari 4 (Mac OS X only; Windows not supported)

NOTE: To use specific features such as the SSH to Host feature or the Policy Editors, you must install the Sun JRE (Java Runtime Environment) 1.6 browser plugin.

NOTE: One Identity recommends that you do not open two sessions of the mangement console in the same browser.

NOTE: One Identity recommends that set your screen resolution to a minimum of 1024 x 768 for the best results.

Network requirements

Authentication Services must be able to communicate with Active Directory including domain controllers, global catalogs and DNS servers using Kerberos, LDAP and DNS protocols. The following table summarizes the network ports that must be open and their function.

Table 10: Network ports
Port Function
389 Used for LDAP searches against Active Directory Domain Controllers. TCP is normally used, but UDP is used when detecting the Active Directory site membership.
3268 Used for LDAP searches against Active Directory Global Catalogs. TCP is always used when searching against the Global Catalog.
88 Used for Kerberos authentication and Kerberos service ticket requests against Active Directory Domain Controllers. TCP is used by default.
464 Used for changing and setting passwords against Active Directory using the Kerberos change password protocol. Authentication Services always uses TCP for password operations.
53 Used for DNS. Since Authentication Services uses DNS to locate domain controllers, DNS servers used by the Unix hosts must serve Active Directory DNS SRV records. Both UDP and TCP are used.
123 UDP only. Used for time-synchronization with Active Directory.
445 CIFS port used to enable the client to retrieve configured group policy.

Note: Authentication Services, by default, operates as a client, initiating connections. It does not require any firewall exceptions for incoming traffic.

Unix administration and configuration

This section explains Authentication Services administration and configuration details relevant to administrators who are integrating Unix hosts with Active Directory.

A separate Administration Guide for Mac OS X is available on the distribution media. While many of the concepts covered in this guide apply to Mac OS X it is recommended that you refer to the Authentication ServicesMac OS X/macOS Administration Guide first when working with Mac OS X.
