LDAP071 - Details

• The SAP error message "LDAP071 LDAP Connector &1: Maximum number of connections exceeded" indicates that the LDAP (Lightweight Directory Access Protocol) connector has reached its maximum limit of concurrent connections to the LDAP server. This can happen due to various reasons, such as configuration settings, high load, or resource limitations.
  
  Cause:
  
  Configuration Limits: The maximum number of connections allowed to the LDAP server may be set too low in the configuration.
  High Load: There may be a high number of concurrent requests being made to the LDAP server, exceeding the configured limit.
  Resource Constraints: The LDAP server itself may have resource constraints or limitations on the number of connections it can handle.
  Connection Leaks: Connections may not be properly closed after use, leading to exhaustion of available connections.
  
  
  Solution:
  
  
  Increase Maximum Connections:
  
  Check the configuration settings of the LDAP server and increase the maximum number of allowed connections if possible.
