Incorrect LDAP Configuration

The configured LDAP server details, such as hostname, port, base DN, bind DN, or password, are incorrect or outdated in SAP S/4HANA settings.

⚠️

Network Connectivity Issues

SAP S/4HANA cannot reach the LDAP server due to firewall restrictions, incorrect DNS resolution, or the LDAP server being offline or unreachable on the network.

⚠️

LDAP Server Unavailable or Overloaded

The external LDAP server is not running, is experiencing high load, or has reached its connection limit, preventing SAP S/4HANA from establishing a connection.

⚠️

SSL/TLS Certificate Problems

If using secure LDAP (LDAPS), issues with expired, invalid, or untrusted SSL/TLS certificates on either the SAP S/4HANA or LDAP server side can cause validation to fail.
