When I'm searching for an non-existent attribute the slapd
writes in its logfile "(?=undefined)" using logmask=256

It would be more helpfully to see the name of the mistyped
attribute for example (vwuuid=undefined). So I would be able
to grep my sources for this mistyped attributename.

may have a look on bug ITS#2506
