Oddly enough it looks like it comes out as part of the LDIF comment.  If you skip the option to tell it to not output ldif comments you'll get your base:

$ ldapsearch -d1 -x "(uid=example)" 2>&1 | grep base

# base <dc=example,dc=com> (default) with scope subtree

Hmmm, that is a really interesting problem. I could not find any solution to it either.

<rant>
from the man page
-d debuglevel
             Set the LDAP debugging level to debuglevel.  ldapsearch must be compiled with LDAP_DEBUG defined for this option to have any effect.

that is just bloody useless, why do I have to google to find a sun man page that contains the actual possible debug levels. Why is it not part of the man page in Red Hat / CentOS ?!!?!?!?!

Lets get rid of man pages save some disk space and find everything with google, who reads man pages anyway.
</rant>
