Users and Permissions for Synchronizing with a Unix-Based Target System

The following users are involved in synchronizing One Identity Manager with a Unix-based target system.

Table 2: Users for Synchronization
User Permissions
User for accessing the Unix host

You must provide a user account with the following permissions for full synchronization of a Unix-based target system with the supplied One Identity Manager default configuration.

  • Permissions for establishing a Secure Shell (SSH) connection to the host.
  • Administration permission for executing write operation in the Unix objects.

One Identity Manager Service user account

The user account for the One Identity Manager Service requires access rights to carry out operations at file level (issuing user rights, adding directories and files to be edited).

  • The user account must belong to the group "Domain Users".
  • The user account must have the extended access right "Log on as a service".
  • The user account requires access rights to the internal web service.

NOTE: If the One Identity Manager Service runs under the network service (NT Authority\NetworkService), you can issue access rights for the internal web service with the following command line call:

netsh http add urlacl url=http://<IP address>:<port number>/ user="NT AUTHORITY\NETWORKSERVICE"

The user account needs full access to the One Identity Manager Service installation directory in order to automatically update the One Identity Manager.

In the default installation the One Identity Manager is installed under:

  • %ProgramFiles(x86)%\One Identity (on 32-bit operating systems)
  • %ProgramFiles%\One Identity (on 64-bit operating systems)
User for accessing the One Identity Manager database

The default system user "Synchronization" is available to run synchronization over an application server.

Setting Up the Synchronization Server

To setup synchronization with a Unix-based target system, a server must be available with the following software installed on it:

  • Windows operating system

    Following versions are supported:

    • Windows Server 2008 (non-Itanium based 64-bit) Service Pack 2 or later
    • Windows Server 2008 R2 (non-Itanium based 64-bit) Service Pack 1 or later
    • Windows Server 2012
    • Windows Server 2012 R2
    • Windows Server 2016
  • Microsoft .NET Framework Version 4.5.2 or later

    NOTE: Microsoft .NET Framework version 4.6 is not supported.

    NOTE: Take the target system manufacturer's recommendations into account.
  • Windows Installer
  • One Identity Manager Service, Unix connector
    • Install One Identity Manager components with the installation wizard.
      1. Select the option Select installation modules with existing database.
      2. Select the machine role Server | Job server | Unix.

All One Identity Manager Service actions are executed against the target system environment on the synchronization server. Entries which are necessary for synchronization and administration with the One Identity Manager database are processed by the synchronization server. The synchronization server must be declared as a Job server in One Identity Manager.

NOTE: If several target system environments of the same type are synchronized under the same synchronization server, it is useful to set up a job server for each target system on performance grounds. This avoids unnecessary swapping of connection to target systems because a job server only has to process tasks of the same type (re-use of existing connections).

Use the Server Installer to install the One Identity Manager Service. This program executes the following steps.

  • Setting up a Job server.
  • Specifying machine roles and server function for the Job server.
  • Remote installation of One Identity Manager Service components corresponding to the machine roles.
  • Configures the One Identity Manager Service.
  • Starts the One Identity Manager Service.

NOTE: The program executes remote installation of the One Identity Manager Service. Local installation of the service is not possible with this program. Remote installation is only supported within a domain or a trusted domain.

To install and configure the One Identity Manager Service remotely on a server

  1. Start the program Server Installer on your administrative workstation.
  2. Enter valid data for connecting to One Identity Manager on the Database connection page and click Next.
  3. Specify on which server you want to install the One Identity Manager Service on the Server properties page.
    1. Select a job server in the Server menu.

      Queue

      Name of queue to handle the process steps. Each One Identity Manager Service within the network must have a unique queue identifier. The process steps are requested by the job queue using exactly this queue name. The queue identifier is entered in the One Identity Manager Service configuration file.

      Full server name

      Full name of the server in DNS syntax.

      Example:

      <name of server>.<fully qualified domain name>

      NOTE: Use the Advanced option to edit other Job server properties. You can use the Designer to change properties at a later date.
  4. Specify which job server roles to include in One Identity Manager on the Machine role page. Installation packages to be installed on the Job server are found depending on the selected machine role.

    Select at least the following roles:

    • Unix
  5. Specify the server's functions in One Identity Manager on the Server functions page. One Identity Manager processes are handled depending on the server function.

    The server's functions depend on which machine roles you have selected. You can limit the server's functionality further here.

    Select at least one of the following server functions:

    • Unix connector
    • AIX connectorWindows PowerShell
  6. Check the One Identity Manager Service configuration on the Service settings page.

Creating a Synchronization Project for initial Synchronization of a Unix Host

Creating a Synchronization Project for initial Synchronization of a Unix Host

Use the Synchronization Editor to configure synchronization between the One Identity Manager database and the Unix-based target system. The following describes the steps for initial configuration of a synchronization project.

After the initial configuration, you can customize and configure workflows within the synchronization project. Use the workflow wizard in the Synchronization Editor for this. The Synchronization Editor also provides different configuration options for a synchronization project.

For more detailed information about setting up synchronization, see the One Identity Manager Target System Synchronization Reference Guide.

Detailed information about this topic

Information Required for Setting up a Synchronization Project

Have the following information available for setting up a synchronization project.

Table 5: Information Required for Setting up a Synchronization Project
Data Explanation

Server name or IP address of the host

Full name or IP address of the host for connecting to the synchronization server to provide access to Unix objects.

Host communications port

Communications port for establishing a Secure Shell (SSH) connection to the host. The default port is TCP port 22.

User account and password for logging onto the host

User account and password for logging onto the host. This user account is used to access the host by SSH. The user account requires permissions for establishing an SSH connection.

Method, user name and password for escalating permissions

Executing commands requires an administrative context. Make a user account available with sufficient permissions. This user account is used to perform write operations on the Unix objects.

Available methods are:

  • Default

    The user that logs in on the host already has administrative permissions.

  • Sudo

    The user for logging in on the host can execute administrative tasks with another user's permissions, for example "root". This is configured in the sudoer file on the host.

  • su

    This method uses the su command for changing the context. Another user with administrative permissions is required.

Synchronization server of the Unix-based target system

All One Identity Manager Service actions are executed against the target system environment on the synchronization server. Entries which are necessary for synchronization and administration with the One Identity Manager database are processed by the synchronization server.

The One Identity Manager Service with the Unix connector must be installed on the synchronization server.

The synchronization server must be declared as a Job server in One Identity Manager. Use the following properties when you set up the Job server.

Table 6: Additional Properties for the Job Server
Property Value
Server Function

Unix connector

AIX connector

Machine role Server/Job server/Unix
One Identity Manager Database Connection Data

SQL Server:

  • Database server
  • Database
  • Database user and password
  • Specifies whether Windows authentication is used.

    This type of authentication is not recommended. If you decide to use it anyway, ensure that your environment supports Windows authentication.

Oracle:

  • Species whether access is direct or through the Oracle client

    Which connection data is required, depends on how this option is set.

  • Database server
  • Oracle instance port
  • Service name
  • Oracle database user and password
  • Data source (TNS alias name from TNSNames.ora)
Remote connection server

To configure synchronization with a target system, One Identity Manager must load the data from the target system. One Identity Manager communicates directly with target system to do this. If you do not have direct access on the workstation on which the Synchronization Editor is installed, because of the firewall configuration, for example, you can set up a remote connection.

The remote connection server and the workstation must be in the same Active Directory domain.

Remote connection server configuration:

  • One Identity Manager Service is started
  • RemoteConnectPlugin is installed
  • Unix connector or AIX connector is installed

The remote connection server must be declared as a Job server in One Identity Manager. The Job server name is required.

TIP: The remote connection server requires the same configuration (with respect to the installed software) as the synchronization server. Use the synchronization as remote connection server at the same time, by simply installing the RemoteConnectPlugin as well.

For more detailed information about setting up a remote connection, see the One Identity Manager Target System Synchronization Reference Guide.
