I am thinking that our 2 MB smbpasswd file is probably becoming a
point of resource contention.  I would like to move over to something
that does not require a linear search, and a passdb.tdb seems the most
obvious quick target - but unfortunately most of the 23,452 entries
are old-style ones of the form:

aa103:60001:<hash>:<hash>:U

without the trailing unique identifiers that the pdbedit command needs
to migrate an smbpasswd file to a passdb.tdb hash.

Does *anyone* know how to process an old-style smbpasswd file to add
the trailing unique identifiers to each entry?!
