@item Use DNS: @var{bool}
The IP address of a client is looked up using DNS when it connects.
Unfortunately, this lookup blocks the entire server, and it can take
several minutes. You can disable DNS lookup with this parameter.
Default is on.
@item DNS log threshold: @var{double}
If the @samp{Use DNS:} parameter is true, the server will measure the
time each DNS lookup takes. If the time exceeds the specified
threshold, an entry will be made in the log. The value is specified
in seconds. The default value is 1.5 seconds. If your libc supports
it, you can enter @code{+inf} to disable logging.
@item Anyone can create new persons: @var{bool}
If this is set, anyone can create a new person, even if he lacks
special bits for doing so. Default is on.
