Users and authorizations for synchronizing with SAP R/3

The following users are involved in synchronizing One Identity Manager with SAP R/3.

Table 2: Users for synchronization

User

Authorizations

One Identity Manager Service user account

The user account for the One Identity Manager Service requires user permissions to carry out operations at file level (adding and editing directories and files).

The user account must belong to the Domain users group.

The user account must have the Login as a service extended user permissions.

The user account requires permissions for the internal web service.

NOTE: If the One Identity Manager Service runs under the network service (NT Authority\NetworkService), you can grant permissions 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 One Identity Manager.

In the default installation, 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 target system (synchronization user)

You must provide a user account with the following authorizations for full synchronization of SAP R/3 objects with the supplied One Identity Manager default configuration.

Required authorization objects and their meanings:

  • S_TCODE with a minimum of transaction codes SU01, SU53, PFCG

  • S_ADDRESS1 (address services) with activities 01, 02, 03, 06 and valid address groups (at least BC01)

  • S_USER_AGR (role maintenance) with activities 02, 03, 22, 78, possibly with a restricted name range (for example Z*)

  • S_USER_GRP (group maintenance) with activities 01, 02, 03, 22, 78 and PP (if available in the SAP R/3 environment)

  • S_USER_AUT (authorizations) with activities 03, 08

  • S_USER_PRO (profile) with activities 01, 02, 03, 22

  • S_USER_SAS (system specific assignments) with activities 01, 06, 22

  • S_USER_UID with the activity 03

  • S_RFC (authorization check by RFC access) with activity 16 at least for function groups ZVI, /VIAENET/ZVI0, /VIAENET/ZVI_L, /VIAENET/Z_HR, SU_USER, SYST, SDTX, RFC1, RFC_METADATA, SDIFRUNTIME, SYSU,

  • /VIAENET/ZVIL_TABLE

    NOTE:

    As of One Identity Manager version 8.2, an updated BAPI transport SAPTRANSPORT_70.ZIP is provided. This replaces the RFC_READ_TABLE SAP module with the /VIAENET/READTABLE function module. When it accesses an SAP R/3 environment, the SAP R/3 connector checks whether the /VIAENET/READTABLE function module exists and uses it.

    If the function module is not available, the connector uses the RFC_READ_TABLE SAP module.

    In this case, the synchronization user needs the authorization object S_TABU_NAM with the activity 03.

    Alternatively you can define access permissions on the tables using the S_TABU_NAM or the S_TABU_DIS authorization object. These are tested equally.

    In the TABLE field, the names of the tables to be read can be specified individually.

Apart from the authorizations listed, the user account has to get all objects from the authorization classes ZVIH_AUT, ZVIA_AUT, and ZVIL_AUT that are installed by the transport package for synchronization. These authorization objects are there to guarantee principal authorization for running function modules.

In addition, the authorization objects ZVIH_OP, ZVIA_OP, ZVIL_OP need to be assigned. This regulates the type of access to SAP R/3 data using the ACTVT authorization field. Possible values are 01 add or create, 02 change, 03 display, 06 delete. The respective activity is checked before accessing data. If only the 03 display activity has been assigned, it means that absolutely no write operations can be carried out with this user account using the One Identity Manager Business Application Programing Interface.

The following authorization objects are required in addition for the child system in order to synchronize central user administration:

  • S_RFC with the function group SUU6

  • S_TCODE with the transaction code SU56

User for accessing the One Identity Manager database

The Synchronization default system user is provided to run synchronization using an application server.

TIP: The transport file provided by default, SAPRole.zip, includes a transport package with a role that the base authorization object already possesses. This role can be assigned to the user account. You will find the transport files on the One Identity Manager installation medium in the Modules\SAP\dvd\AddOn\Bapi directory.

The named authorizations are required so that the SAP R/3 connector has read and write access to the SAP R/3 system. If only read access is permitted, set up a profile that has authorizations for carrying out for transactions SU01 and PFCG but prevents write access at activity or field level. Also be aware of granting authorizations for activities regarding the authorization objects ZVIH_OP, ZVIA_OP, ZVIL_OP. If access is read-only, only the 03 display activity is enabled.

The user account requires the user type dialog, communication, or system to load more information.

NOTE: In SAP R/3 versions up to and including SAP Web Application Server 6.40, the password and user input are not case-sensitive. this no longer applies to the password for SAP NetWeaver Application Server 7.0 and later. Passwords are case sensitive.

All SAP’s own tools that are supplied up to SAP Web Application Server 6.40, apart from the SAP GUI (RFC-SDK, SAP .Net Connector), therefore change the password to capital letters before passing them to SAP R/3. You must set the password in capital letters for the user account used by the SAP .Net Connector to authenticate itself on the SAP R/3 system. If this is done, all the usual tools can be accessed on SAP NetWeaver Application Server 7.0 by RFC.

Setting up the synchronization server

To set up synchronization with an SAP R/3 environment, a server has to be available that has the following software installed on it:

  • Windows operating system

    The following versions are supported:

    • Windows Server 2022

    • Windows Server 2019

    • Windows Server 2016

    • Windows Server 2012 R2

    • Windows Server 2012

  • Microsoft .NET Framework version 4.8 or later

    NOTE: Take the target system manufacturer's recommendations into account.
  • Windows Installer
  • SAP .Net Connector 3.1 for x64, with at least version 3.1.2.0, for Microsoft .NET 4.8
  • One Identity Manager Service, Synchronization Editor, SAP R/3 connector
    • Install One Identity Manager components with the installation wizard.
      1. Select Select installation modules with existing database.
      2. Select the Server | Job Server | SAP R/3 machine role.

Further requirements

  • Following files must either be in the Global Assemblies Cache (GAC) or in the One Identity Manager installation directory.
    • libicudecnumber.dll
    • rscp4n.dll
    • sapnco.dll
    • sapnco_utils.dll
  • Following files must either be in the Global Assemblies Cache (GAC) or in C:\Windows\System32 or in the One Identity Manager's installation directory.
    • msvcp100.dll
    • msvcr100.dll

All One Identity Manager Service actions are run against the target system environment on the synchronization server. Data entries required 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 recommended that you set up a Job server for each target system for performance reasons. This avoids unnecessary swapping of connections to target systems because a Job server only has to process tasks of the same type (re-use of existing connections).

To set up a Job server, perform the following steps.

  1. Create a Job server and install and configure the One Identity Manager Service.

    Use the One Identity Manager Service to install the Server Installer. The program runs the following steps:

    • Sets up a Job server.

    • Specifies machine roles and server function for the Job server.

    • Installs One Identity Manager Service components corresponding to the machine roles.

    • Configures the One Identity Manager Service.

    • Starts the One Identity Manager Service.

    Use the Server Installer to install the One Identity Manager Service locally or remotely.

    To remotely install the One Identity Manager Service, provide an administrative workstation on which the One Identity Manager components are installed. Ensure that the One Identity Manager components are installed on the server before installing locally. For more information about installing One Identity Manager components, see the One Identity Manager Installation Guide.

  2. If you are working with an encrypted One Identity Manager database, declare the database key in the One Identity Manager Service. For more information about working with an encrypted One Identity Manager database, see the One Identity Manager Installation Guide.

  3. To generate processes for the Job server, you need the provider, connection parameters and the authentication data. By default, this information is determined from the database connection data. If the Job server runs through an application server, you must configure extra connection data in the Designer. For more information about connection data, see the One Identity Manager Configuration Guide.

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

  1. Start the Server Installer program.

    NOTE: To install remotely, start the Server Installer program on your administrative workstation. To install locally, start the program on the server.

  1. On the Database connection page, enter the valid connection credentials for the One Identity Manager database.

    You can connect via the application server or directly to connect to the database.

  2. On the Server properties page, specify the server on which you want to install the One Identity Manager Service.

    1. Select a Job server from the Server menu.
