Issue/Introduction

After upgrading to version 24.4.x the LDAPSync, the application regularly fails to connect to LDAPS server during the bind step. 

The errors are always the same (connection is reset after just 1ms):

2025-11-20 16:41:49.312 [main] o.a.d.l.c.a.LdapNetworkConnection        DEBUG  MSG_04104_SENDING_REQUEST (MessageType : BIND_REQUEST
Message ID : 1
    BindRequest
        Version : '3'

)
2025-11-20 16:41:49.313 [main] o.a.d.l.c.a.LdapNetworkConnection        DEBUG  MSG_04106_ADDING (1,org.apache.directory.ldap.client.api.future.BindFuture)
2025-11-20 16:41:49.313 [NioProcessor-1] o.a.d.l.c.a.LdapNetworkConnection        WARN   Connection reset

Rolling back to version 24.3.0 resolves the issue and the synchronization completes successfully.

We also observed that if we use ldap instead of ldaps, the ldapsync 24.4 works fine all the time.

Cause

DE179040
