LDAP connection has been closed error during task execution in Identity Manager

Issue/Introduction

Intermittent failures are observed during task execution in CA Identity Manager (IM). Events such as CreateUserEvent fail with the error message:

ERROR MESSAGE: LDAP connection has been closed. 

This issue does not occur for every task but appears sporadically during user management operations.

 

Environment

Identity Manager 14.5, v15

Resolution

To resolve this issue, investigate the network infrastructure settings between the application and the user store:

Check Load Balancer/Firewall Settings: Review the idle connection timeout settings on your Load Balancer or Firewall.

Adjust Timeouts: Ensure the network device's idle timeout is properly aligned with the application's connection lifecycle to prevent premature termination of active or pooled LDAP connections.

Validate connectivity: Monitor the Identity Manager logs and event states to ensure that CreateUserEvent and other LDAP-dependent tasks complete successfully after the network adjustments.
