HP-UX

Here's how the HP CIFS Client and Server handle user-level security.
Admittedly rather quirky, but it works; you just have to follow the rules.

i. In the Samba configuration file, under the entry for the share, you give
a list of one or more usernames. These are the users whose passwords are
used by Samba to authenticate client requests to access the share (this will
make sense later). For example:

[global]
security = share
encrypt passwords = yes

[share]
path = /export/share
username = userA userB

ii. On the cifsclient, root mounts the share:

cifsmount server:/share /mountpoint

Root may also provide a username and password (-U and -P), subject to constraints
described below.

iii. On the cifsclient, whoever wants to access the share must be autheticated
via cifslogin:

cifslogin [-U username] //server/share
Share Password for \\SERVER\SHARE:****

Note that if you use this syntax:

cifslogin [-U username] server

you will first get this prompt:

Login to Share:

which is asking for the share name; then you will get the "Share Password..." prompt.

but i don't know why it gives error now...
