Modify the attribute olcAuthIDRewrite in cn=config and you get:
conn=0 op=7 RESULT tag=103 err=80 text=<olcAuthIDRewrite> handler exited with 1
It seems to do this with 2.4.18 and 2.4.19 as well as the version I downloaded from the CVS tonight (2009-11-20).
If others don't seem to have the same problem, I'd be happy to list more information about my setup. This is my first ITS bug, so if you need more info about something, let me know and I can provide.
