</listitem>
</varlistentry>
<varlistentry>
<term>debug</term>
<listitem><para>Set debug level to the value specified by the
parameter. This can be sent to any of the destinations. If this
message is sent to either the smbd or winbindd daemons, the parent
process will rebroadcast the message to all child processes changing
the debug level in each one.</para>

<title>AUTHOR</title>
<para>The original Samba software and related utilities
were created by Andrew Tridgell. Samba is now developed
by the Samba Team as an Open Source project similar
to the way the Linux kernel is developed.</para>
<para>The original Samba man pages were written by Karl Auer.
The man page sources were converted to YODL format (another
excellent piece of Open Source software, available at <ulink url="ftp://ftp.icce.rug.nl/pub/unix/">
ftp://ftp.icce.rug.nl/pub/unix/</ulink>) and updated for the Samba 2.0
release by Jeremy Allison. The conversion to DocBook for
Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for
Samba 3.0 was done by Alexander Bokovoy.</para>
