Hello,
Please, i need help with security mode = share.
i want to configure security = share and the parameter "username = user"
in a shared folder to avoid that everybody could access to it. f I have
understood correctly the manual, this configuration enables to access if
the password provided matches with the user`password. But when i try to
access returns this error:
smbclient //SERVER/Docs
Enter user's password:
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.4.7]
Server not using user level security and no password supplied.
tree connect failed: NT_STATUS_WRONG_PASSWORD

I also tried:
smbclient -U user%passwd //SERVER/Docs
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.4.7]
Server not using user level security and no password supplied.
tree connect failed: NT_STATUS_WRONG_PASSWORD

smbclient -U user%passwd //SERVER/Docs -P
Failed to open /var/lib/samba/secrets.tdb
ERROR: Unable to open secrets database

sudo smbclient -U user%passwd //SERVER/Docs -P
ERROR: Unable to fetch machine password for SERVER$@ in domain
WORKGROUP

If i change "passdb backend = smbpasswd" in GLOBAL options:

smbclient -U user%passwd //SERVER/Docs -P -e -A
/etc/samba/smbpasswd
ERROR: Unable to open credentials file!

sudo smbclient -U user%passwd //SERVER/Docs -P -e -A
/etc/samba/smbpasswd
ERROR: Unable to fetch machine password for SERVER$@ in domain
WORKGROUP

My system:
Linux user-laptop 2.6.32-23-generic #37-Ubuntu SMP x86_64 GNU/Linux

My config:

testparm

Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.4.7]
smb: \> quit
user(a)user-laptop:~$ testparm
