SAP S/4HANA Error 4202: Invalid LDAP Provider Name
Description
This error indicates that the Lightweight Directory Access Protocol (LDAP) server configuration in SAP S/4HANA contains an invalid or unrecognized provider name. It typically occurs during user authentication, directory synchronization, or when attempting to connect to an external LDAP directory service, preventing successful communication.
Error Message
ERR_LDAP_INVALID_PROVIDER_NAME
Known Causes
4 known causesMisconfigured Provider Name
The LDAP provider name specified in the SAP S/4HANA system configuration does not match any defined or available LDAP server configurations.
Typographical Error
A simple typo, incorrect capitalization, or spacing issue in the provider name during manual entry or setup.
LDAP Server Not Registered
The external LDAP server corresponding to the provider name might not be correctly registered or active within the SAP S/4HANA system's landscape.
Incorrect System Landscape Setup
The overall system landscape configuration for LDAP integration might be incomplete or incorrectly set up, leading to the provider name being unresolvable.
Solutions
3 solutions available1. Verify and Correct LDAP Provider Configuration in SAP S/4HANA easy
Ensures the LDAP provider name in SAP S/4HANA matches the actual provider name configured in the system.
1
Log in to your SAP S/4HANA system with an administrator role.
2
Navigate to the transaction code `LDAP` (or `SM30` and enter table `LDAPSERVER`).
3
Locate the entry that is causing the error. The error message 'ERR_LDAP_INVALID_PROVIDER_NAME' usually indicates an incorrect provider name.
4
Compare the 'Provider Name' field in this entry with the actual name of your LDAP server or directory service. This might involve checking your operating system's network configuration or the specific LDAP server's configuration.
5
Correct the 'Provider Name' field to match the exact name of your LDAP provider. Ensure there are no typos or extra spaces.
6
Save the changes.
7
Test the LDAP connection again to confirm the error is resolved.
2. Check System Landscape Directory (SLD) for LDAP Server Information medium
Verifies that the LDAP server is correctly registered and configured in the SAP System Landscape Directory (SLD).
1
Access the SAP SLD user interface. The URL is typically `http://<host>:<port>/sld`.
2
Log in with appropriate credentials.
3
Navigate to 'Software Components' or 'Servers' and search for your LDAP server entry.
4
Verify that the LDAP server is correctly registered and that its hostname or IP address and port are accurate.
5
Ensure the 'Provider Name' or equivalent identifier in the SLD matches what is expected by SAP S/4HANA. Sometimes, the SLD acts as a central source of truth for such configurations.
6
If the SLD entry is incorrect or missing, update or create it accordingly. You might need to use SLD tools or consult your infrastructure team.
7
After updating SLD, it might be necessary to restart relevant SAP S/4HANA components or services for the changes to take effect. Consult SAP notes for specific restart procedures if needed.
3. Review and Re-establish LDAP Server Connection Details medium
Performs a comprehensive check and potential re-configuration of the LDAP server connection parameters within SAP S/4HANA.
1
Log in to SAP S/4HANA and navigate to transaction `LDAP`.
2
Identify the LDAP server configuration entry causing the error.
3
Carefully review all fields, including: 'Provider Name', 'Host', 'Port', 'Bind DN', 'Bind Password', and 'Search Base'.
4
Confirm that the 'Provider Name' is correct and unique. If you have multiple LDAP providers, ensure each has a distinct and accurate name.
5
Verify the 'Host' and 'Port' are reachable from the SAP S/4HANA application server. You can use basic network tools like `ping` and `telnet` from the application server's operating system to test connectivity.
ping <ldap_host>
telnet <ldap_host> <ldap_port>6
Double-check the 'Bind DN' and 'Bind Password' for any typos or expired credentials. These are crucial for authentication with the LDAP server.
7
Consider temporarily removing and re-adding the LDAP server configuration with the correct details. This can sometimes resolve underlying configuration inconsistencies.
8
Save the updated configuration and test the LDAP connection.
