You're welcome. Unfortunately, it appears I missed something in merging the
CVS version into 2.1.23. You should probably stick with the 2.1.22 ldapdb.c
for now, will have to fix this in 2.1.24.
Also in this otherwise excellent summary:

The sasl-regexp statements are in the wrong order. The statements are matched
in the order that they're listed in slapd.conf. You must put the most
specific statement first, otherwise it will never be used. This is already
stated in the documentation, yet it seems that everyone overlooks it.
