access log for OpenLDAP

[Sebastian Moeller <Sebastian_Moeller@web.de>]

hi all,

I'm looking for some kind of an access log for OpenLDAP, especially for 
"mod"(-ify) access.
The log-level directive in slapd.conf only allows to log _all_ access 
(read, search, modify...). Ok, loglevel 256 is close to what I'm looking 
for, but I don't need these megabytes of information with an very fast 
increasing log.
I just want to log the modify events with the dn and/or an IP.

I think that this is not an unusual requirement. Any suggestions for my 
problem? How would you manage an openLDAP-server where many people have 
read/write access? The admin just wants to let the users know, that they 
shouldn't play around with the directory, because he can see who deleted 
some entries (for example).

Thanks
Sebastian
