Dancing in Samba rhythm

Sometimes I want to use Samba as fast as possible. Unfortunately there may occur unexpected problems during user authentication. Following sequence of commands solves many of them:

smbpasswd user_name
pdbedit -a user_name

In other words, adding user and setting up password may not have been enough, we need to add him/her to user database.

Mount:
sudo mount -t cifs //netbiosname/sharename /media/sharename

Options:
-o \
username=winusername, \
password=winpassword, \
iocharset=utf8, \
file_mode=0777, \
dir_mode=0777 \

Or:
guest, \
rw
