[Samba] homedir login account issue

[Shahid Hussain]

 I am having problem with Samba 2.x.
 I am be able to login to Samba without a problem :).  When I login to 
"Shahid" account it directed to "/home/shahid" but I can still can see 
another user home dir too? why that

so like I login as "shahid" account then can see "/home/shahid" but why I 
can see " /home/test" too - it shouldnt be?
Each user should have own homedir only.

What did I do wrong? look below, thanks!
