After generating an LDIF file using ldapsearch having a direct fast connect to the LDAP directory, attempt to re-import the file have succeeded while being on the local network. However attempt to import the same LDIF file over a WAN connection fail with the following error: ldapadd -c -D "..." -w ... -x -h ... -p 389 -f test2.ldif adding new entry "..." ldap_add: Already exists (68) adding new entry "..." ldap_add: Already exists (68) adding new entry "..." ldap_add: Protocol error (2) additional info: no attributes provided adding new entry "..." ldap_add: Already exists (68) .. adding new entry "..." adding new entry "..." .. adding new entry "..." ldapadd: update failed: ... ldap_add: Can't contact LDAP server (-1) .. All messages after this file with the same error (-1). It seems that the slower connection is causing a Protocol error which results in LDAP falling over, or at least becoming un-available. Any ideas what could be causing this problem and what I could to address this. Regards Alex
