	<para>This parameter allows an admin to define the character 
	used when listing a username of the form of <replaceable>DOMAIN
	</replaceable>\<replaceable>user</replaceable>.  This parameter 
	is only applicable when using the <filename moreinfo="none">pam_winbind.so</filename>
	and <filename moreinfo="none">nss_winbind.so</filename> modules for UNIX services.

	<para>Please note that setting this parameter to + causes problems
	with group membership at least on glibc systems, as the character +
	is used as a special character for NIS in /etc/group.</para>
