slapd uses type ID to refer to an entry from an index.
On my system this is defined in slap.h to be an unsigned
long, sizeof(unsigned long) == 4. One of this range
is reserved to be NOID, so you can have 2^32 - 1 maximum
number of entries (DNs). Probably somewhat less than the
256 TB (unless you're really storing a whole lot of data
under each DN).
