previous logged user's home dir is seen

[TAKAHASHI Motonobu]

Hi, 

There is a probrem that:
for example, if there is a Samba PDC which also offers users's home
directories, when a certain user logged off and another user
logged on immediately to the Samba PDC, the previous user's home
directory will appear in the share list.

The patch bellow is fixed this problem for Samba 2.2.2, 
Samba 2.0.10 and Samba HEAD branch can be fixed with the same
approach.
