SAP S/4HANA Error 4196: LDAP Role Mapping Missing
Description
This error indicates that an SAP S/4HANA role cannot be successfully mapped to an existing LDAP group. It typically occurs during user authentication or authorization attempts when the system tries to resolve permissions based on external directory services.
Error Message
ERR_LDAP_MAPPING_DOESNT_EXIST
Known Causes
4 known causesIncorrect LDAP Group Name
The LDAP group name specified in the SAP S/4HANA role mapping configuration does not exactly match an existing group in the LDAP directory.
Missing Role-to-Group Configuration
No mapping has been defined in SAP S/4HANA to link the specific user role to any LDAP group.
LDAP Group Deleted or Renamed
The corresponding LDAP group, which was previously mapped to an SAP S/4HANA role, has been deleted or renamed in the LDAP directory.
Synchronization Issues
There might be a delay or failure in synchronizing LDAP directory changes with the SAP S/4HANA system, leading to outdated mapping information.
Solutions
3 solutions available1. Verify and Create LDAP Role Mapping in SAP Identity Management medium
Ensure the necessary LDAP role mapping exists within SAP Identity Management (IdM) and create it if absent.
1
Access SAP Identity Management (IdM) system. This is typically done via a web browser using the IdM portal URL.
2
Navigate to the role mapping configuration. The exact path may vary slightly based on your IdM version, but generally look for sections related to 'Identity Lifecycle Management', 'Role Management', or 'LDAP Configuration'.
3
Search for the specific LDAP role mapping that is expected to exist and is referenced in the error message (e.g., a mapping from an LDAP group to an SAP S/4HANA role or user group).
4
If the mapping is missing, create a new one. This involves defining the source (LDAP attribute/group) and the target (SAP S/4HANA role/group). You will need to know the exact DN (Distinguished Name) of the LDAP group and the identifier for the target SAP S/4HANA role or user group.
5
Save the newly created or modified role mapping configuration.
6
Restart the relevant SAP S/4HANA services or the entire application server to ensure the changes are picked up. Alternatively, trigger an IdM synchronization if applicable.
2. Check and Correct LDAP Attribute Configuration for Role Assignment medium
Review the LDAP connector configuration to ensure the correct attribute is used for role assignment and that it's properly populated.
1
Log in to your SAP S/4HANA system using a user with administrative privileges (e.g., SAP_ALL profile).
2
Execute transaction code `LDAP` to access the LDAP configuration. This transaction allows you to manage the connection to your LDAP server and define how user attributes are mapped.
3
Navigate to the connector configuration that is being used for user authentication and/or role retrieval. Identify the attribute that is supposed to carry the role information from LDAP (e.g., `memberOf`, `groupMembership`, or a custom attribute).
4
Verify that this attribute is correctly specified in the LDAP connector configuration. Ensure it matches the attribute used in your LDAP directory service to store group memberships.
5
If the attribute is incorrect, modify the configuration to point to the correct LDAP attribute. Save your changes.
6
Test the LDAP connection and user synchronization to confirm that the corrected attribute is being read and processed correctly.
3. Synchronize LDAP Groups with SAP S/4HANA User Groups easy
Manually trigger or ensure scheduled synchronization of LDAP groups to their corresponding SAP S/4HANA user groups.
1
Access SAP S/4HANA system via SAP GUI.
2
Execute transaction code `SU01` to manage user master data. While not directly for synchronization, it's a good place to verify user and group assignments.
3
Alternatively, if you are using SAP Identity Management (IdM), navigate to the synchronization jobs or tasks within the IdM portal. Look for tasks related to 'LDAP Group Synchronization' or 'User Group Mapping'.
4
Manually trigger the synchronization job. This will force the system to re-read LDAP group memberships and update the corresponding SAP S/4HANA user groups.
5
Monitor the synchronization job for any errors. If errors occur, investigate them further using IdM logs or system logs.
6
After successful synchronization, check `SU01` or the relevant user management transaction to confirm that the user's group memberships have been updated correctly based on their LDAP group assignments.
