I have uploaded Neil Dunbar's constraint overlay, and patches to auxiliary build
files such as the Makefile.in in the overlays directory, the top level
configure.in, and portable.h.in. The constraint overlay limits the values which
can be placed into an attribute, over and above the limits placed by the schema.
It traps only LDAP adds and modify commands (and only seeks to control the add
and modify value mods of a modify). The constraint can be specified as a
character set (e.g. US-ASCII) or as a regular expression.
