Can I have oplocks enabled without problems?

[David Collier-Brown]

  Never turn on oplocks for databases: NT auto-recognizes and 
turns them off for you, Samba has to be told.

  If you do, the first person to open the database will get
an entire copy of it copied to their machine, to use locally.
As soon as the second person logs on, though, the first one will
be stopped (by an oplock break), will have to copy it
all back to the server, and only then will be able to work.

  This produces HORRIBLE delays for the first two users, who
will report the Samba server has bad performance.
