Re: debugging OpenLDAP client
Well, the question is what log level will print out ASNs?

Dieter,
I understand that if strace(1) is available, it can be used. I want to learn how to lift the relevant debug information from the OpenLDAP server. Specially, I would love to see decoded requests and responses. It can be quite helpful in realizing whether the client author messed up the request, or the unexpected response is due to its' decoding error.
Compile with --enable-debug (if this default was overridden) and set an appropriate olcLogLevel to get the messages. This is often accomplished in practice using the -d command line argument, rather than a permanent config change. If your server is under live load, trying this from the client (e.g. ldapsearch(1)) may be a wise approach.
See Table 6.1 in the OpenLDAP 2.4 Administrator's Guide for the available levels (please note that some levels are only relevant in slapd(8) context).
Sincerely,
Igor Shmukler

Hello,
I wrote a client to make RFC 2696 (paged results) requests. My client
gets results fine, yet size and cookie values are always 0, "" - this
should not be the case. I tried with ldapsearch(1) and it does paging
fine. Hence, it makes sense to assume that the server is OK and
opaque/cookie must not be empty. At the same time, format of my ASN
object is fine.
I need to understand where exactly, I messed up.

depending on your programming language, you may run your client with
strace or similar tools.
