[Samba] Samba server behaves not as I want it to

[Ham MI-LY, Gerhard Stehr]

Hi there,

I am trying to set up a samba server on AIX and I am able to mount
filessystems on the Windows2000 PC. But, I want to have several
filesystems
only accessed after given login and password of the owner and some
writable to all
without password (/tmp). 

The /tmp FS works fine. At mounting the others the system asks me for a
login/password first. But
when I entered one I can either read all the others (no password
prompting anymore) or
the system asks me for a username and password, but says the filesystem
is already in use with another
username and should be released first, which is very strange in my
opinion... (this is the actual
configuration)

Who do I have to configure samba the right way. I didn't find anything
useful in the documentations.

Kind regards
Gerhard

My smb.conf file is as follows (there is also a smbpasswd file with 4
users in it):

#======================= Global Settings

[global]

   workgroup = WORKGROUP 
   server string = Samba 
   netbios name = ZAPHOD

   log level = 1
   security = server
#   map to guest = Bad User
   encrypt passwords = no 
#   username map = /usr/local/samba/users.map
#   map to guest = Never

# Use password server option only with security = server
# The argument list may include:
#   password server = My_PDC_Name [My_BDC_Name] [My_Next_BDC_Name]
# or to auto-locate the domain controller/s
   password server =  10.63.253.52
;  password server = <NT-Server-Name>

   socket options = TCP_NODELAY
