• What is the cause and solution for SAP error message LDAPRC051 - LDAP server is overloaded ?

  The SAP error message "LDAPRC051: LDAP server is overloaded" indicates that the LDAP (Lightweight Directory Access Protocol) server is experiencing high load or resource constraints, which prevents it from processing requests efficiently. This can lead to performance issues or failures in authentication and directory services within SAP systems that rely on LDAP for user management.
  Causes:
  
  High Traffic: A sudden increase in the number of requests to the LDAP server can overwhelm it.
  Insufficient Resources: The server may not have enough CPU, memory, or disk I/O capacity to handle the current load.
  
  Configuration Issues: Misconfigurations in the LDAP server settings can lead to inefficient processing of requests.
  Network Issues: Latency or connectivity problems between the SAP system and the LDAP server can exacerbate the perception of overload.
  Inefficient Queries: Poorly optimized queries or excessive search requests can put additional strain on the server.
  
  Solutions:
  
  Monitor Server Performance: Use monitoring tools to check the CPU, memory, and network usage
