	<para>
	Mapping usernames with the <smbconfoption name="username map"/>
	or <smbconfoption name="username map script"/>
	features of Samba can be relatively expensive.
	During login of a user, the mapping is done several times.
	In particular, calling the <smbconfoption name="username map script"/>
	can slow down logins if external databases have to be queried from
	the script being called.
	</para>

	<para>
	The parameter <smbconfoption name="username map cache time"/>
	controls a mapping cache. It specifies the number of seconds a
	mapping from the username map file or script is to be efficiently cached.
	The default of 0 means no caching is done.
