[Samba] Roaming profiles errors and shares not disconnecting

[Philippe LAUGET]

Hi,

We are using Samba 3.0.22 on FreeBSD 5.5 PDC with ldap backend and 
roaming profiles.

We meet some difficulties when users logout from some Windows 2000 SP4 
clients, and storing their profiles back to the Samba server.

The file NTUSER.DAT seems to be uploaded and stored in lowercase, as 
ntuser.dat.
Then, when users try to reopen a win session, they get a corrupted new 
profile. This new profile is fully broken, since it's not possible to 
modify any options that affect NTUSER.DAT.

When they disconnect, smbstatus shows the user as connected on the 
machine for a long time ( from 15 minutes to hours ) after he has logged 
out. The shares that has been mounted on the client do not seem to be 
disconnected.
Here is the output of smbstatus for user test 15 minutes afters he has 
logged out :

Here is some relevant part of smb.conf :

[global]

   force user     = %U
   valid users    = %S
   max connections= 8

[netlogon]
   path           = /export/samba/netlogon
   browseable     = no
   writable       = no

[profiles]
   path           = /export/samba/profiles
   read only      = No

   directory mask = 0700

   browseable     = yes
   read only      = no
   create mask    = 0640
   directory mask = 0770
   force group    = wusers
   valid users    = @wadms, at wusers

----------- EOF ----------------

Is there a way to force these shares to close really when users logout ?

Thank for your help.
