I don't understand what you try to say me but I have the feeling that I 
did not explained well. I will try again:

The CentOS computer logs on locally always with the same user: LocalUser

Once I logged on CentOS with LocalUser user:

I connect to the NAS (\\NAS\sharedA) from "Connect to Server">> "Shared 
Windows" as userA.

I disconnected from the NAS as userA ejecting the volume on the Desktop.

I connect to the NAS (\\NAS\sharedB) from "Connect to Server">> "Shared 
Windows" as userB.

I disconnected from the NAS as userB ejecting the volume on the Desktop.

Now, from any window of Gnome Desktop I write smb://ip-nas/ and I have 
access to sharedA and sharedB.

In fact, if I do netstat -an I can see four connections to the NAS, two 
for every user (139 tcp and 445 tcp) what are saying I'm not really 
disconnected from the NAS.

How can I really disconnect from NAS? Or how can I force the password 
being asked every time I try to access to one shared ressource as 
happens in Debian?
