If you define the index before adding the attribute then it will be
built up on the fly. If the attribute already exists in the directory
and then you define the index, then you must run slapindex.
By the way, after some more research/benchmarking, we've found a way to
make slapindex significantly faster on large databases. The code is now
in OpenLDAP's CVS HEAD. (see the back-bdb "linearindex" config option.)
And another note, if you only need to run slapindex because you've added
a new index, then you should run it with all the other indices commented
out. That will also make things much faster, since it won't waste time
working on existing indices that don't need updating.
