There should not be any problem with this.  You may want to
try adding with them with ldapadd to get schema checks.

As this with a released version, please submit an ITS with
debugger backtrace.

This indicates that a pointer was freed twice.... which implies
that the pointer was used after being freed (the first time).

This may be a completely independent bug.

Submit ITS with backtraces.  I'd be just grabbing at straws
to guess at what the problem might be without a backtrace.

This is generally limited by the underlying database, not
back-ldbm.  I've built much larger directories using BerkeleyDB.
