Hello, I’m trying to analyse the requests done to my ldapserver from a nas. While browsing the logs I found the following entries :

What I see is that in the first case I have err=4, from what I have found it means size limit exceeded. Do you have an explanation of the first anwser ? Is there any param that can be in the request to cause the err=4 ? Maybe I should rise the logLevel to find the difference between the two requests ? Thanks in advance for any hint... — Frédéric Goudal Ingénieur Système, DSI Bordeaux-INP +33 556 84 23 11
