Management Console for Unix requirements

One Identity recommends that you install One Identity Management Console for Unix, a separate One Identity product that provides a management console that is a powerful and easy-to-use tool that dramatically simplifies deployment of Safeguard Authentication Services agents to your clients. The management console streamlines the overall management of your Unix, Linux, and macOS 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 platforms

Can be installed on the following configurations:

  • Windows x86 (32-bit)
  • Windows x86-64 (64-bit)
  • Unix/Linux systems for which Java 8 is available
Server requirements

The Management Console for Unix server requires Java 8 (also referred to as JRE 8, JDK 8, JRE 1.8, and JDK 1.8).

  • 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.
  • Management Console for Unix does not support Security-Enhanced Linux (SELinux)
  • When you install Safeguard Authentication Services on Oracle Solaris 11, the Oracle Solaris 10 packages are installed.
Default memory requirement

NOTE: See JVM memory tuning suggestions in the One Identity Management Console for Unix Administration Guide for information about changing the default memory allocation setting in the configuration file.

Network requirements

Safeguard 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 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. Safeguard Authentication Services always uses TCP for password operations.
53 Used for DNS. Since Safeguard 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: Safeguard 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 Safeguard Authentication Services administration and configuration details relevant to administrators who are integrating Unix hosts with Active Directory.

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