IDAP Configuration in SAP GRC: A Step-by-Step Guide

Identity and Directory Access Protocol (LDAP) is a cornerstone of user management within large organizations. SAP Governance, Risk, and Compliance (GRC) integrates with LDAP directories to streamline user provisioning, access management, and compliance initiatives. Configuring this link is a crucial part of any GRC implementation.

Why Connect GRC to LDAP?

• Centralized User Repository: LDAP is a single source of truth for user data, eliminating manual data entry and inconsistencies across systems.
• Streamlined Access Requests and Provisioning: GRC leverages the data from LDAP to automatically populate requests and accurately provision access based on user roles.
• Enhanced Compliance: GRC can use LDAP attributes to enforce segregation of duties (SoD) and monitor access rights, reducing compliance risks.

Prerequisites

Before starting, gather this information from your LDAP administrator:

• LDAP Server Hostname or IP Address: The location of your LDAP server.
• Port Number: Typically 389 (standard LDAP) or 636 (secure LDAP).
• Bind Credentials: A username and password with read permissions on the LDAP directory.
• Base DN: The starting point for user searches within the LDAP tree.
• LDAP Attributes: The specific attribute names in your LDAP schema that correspond to user information (e.g., first name, last name, email, organizational unit).

Steps for LDAP Configuration in SAP GRC

1. Create an RFC Destination
   • Use transaction SM59 to create a new RFC destination type ‘T’ (TCP/IP connection).
   • Set the Program ID to the same name as the RFC destination. The LDAP connector will use this.
   • Specify the appropriate gateway options for your network landscape.
2. Create the LDAP Connector
   • Access the SAP GRC configuration (transaction SPRO).
   • Navigate to Governance, Risk, Compliance → Access Control → Maintain Connectors.
   • Create a new connector and select ‘LDAP’ as the Connector Type.
   • Provide the RFC destination created in step 1, relevant search filters, and the Base DN of your LDAP tree.
3. Define Field Mapping
   • Determine which LDAP attributes map to corresponding fields in SAP GRC (e.g., User ID, First Name, Last Name).
   • Maintain this mapping in the Connector configuration. This ensures that user data is imported and exported properly.
4. Assign the Connector to a Group
   • Create or use an existing Connector Group.
   • Assign the LDAP connector to this group, enabling the connector for use.
5. Configure Integration Scenarios
   • In transaction SPRO: Governance, Risk, and Compliance → Access Control → Maintain Data Sources
   • Configure the integration scenarios relevant to your use case:
     • AUTH: User authentication against LDAP
     • PROV: User provisioning from LDAP
     • User Search and User Detail data sources may also be configured as needed.
6. Testing and Troubleshooting
   • Thoroughly test user creation, updates, and deletion processes in a non-production GRC environment.
   • Use transaction LADT (LDAP Administration Tool) to check connectivity and troubleshoot configuration issues.
   • Refer to SAP documentation or the SAP Community Network for more detailed troubleshooting steps.

Important Considerations

• Security: For sensitive data, use secure LDAP (LDAPS) with SSL/TLS to protect data in transit.
• Performance: Optimize search filters and queries for large LDAP implementations to ensure efficient operation.
• Data Synchronization: Set up periodic synchronization to align GRC and LDAP user data.

Conclusion

Following these steps and carefully considering security and performance’ll establish a robust connection between SAP GRC and your LDAP directory. This foundation allows you to streamline user management, enhance access control, and improve your overall compliance posture within your organization.
