Nice explanation of what/how to do this, Donna.  Say, can you set some
paver-stones for a patio (10' X 12' rectangle please)...I need to do
this at my house, and if you do it first and put the instructions here,
I'm sure I'll have no problems when I go to do mine.

Have a great week!

the i&i products (including samba) tended to be pretty os version
independent.  it's not a hard & fast rule...but usually you can get
away with putting i&i products on older releases of the os.

i think so too....but (afaik) it has nothing to do with being on 6.0.

in order to log on as a specific user, you have to define that user to
samba.  additionally, the password you give (when adding the user to
samba) has *nothing* to do with that user's mpe password (kinda spooky
:-) nor does this password have to comply with mpe requirements (like
length or character restrictions (even more weird)).

in the shell -- as manager.sys -- navigate your way to
   /SAMBA/SMB228A/bin

the program you want is smbpasswd.  here's the help text:

/SAMBA/SMB228A/bin: ./smbpasswd -h
When run by root:
    smbpasswd [options] [username] [password]
otherwise:
    smbpasswd [options] [password]

Version: 2.2.8a
options:
  -L                   local mode (must be first option)
  -h                   print this usage message
  -s                   use stdin for password prompt
  -c smb.conf file     Use the given path to the smb.conf file
  -D LEVEL             debug level
  -r MACHINE           remote machine
  -U USER              remote username
extra options when run by root or in local mode:
  -a                   add user
  -d                   disable user
  -e                   enable user
  -m                   machine trust account
  -n                   set no password
  -x                   delete user
  -j DOMAIN            join domain name
  -t DOMAIN            change trust account password on domain
  -S DOMAIN            Retrieve the domain SID for DOMAIN
  -R ORDER             name resolve order
  -W S-1-5-...         Write the SID S-1-5-... to the secrets file
  -X SERVER|DOMAIN     Extract SID for SERVER or DOMAIN from the
secrets file

the option you want is '-a'.  i've always added users in all upper as
USER.ACCOUNT.  i'm not sure that case makes a difference...but otoh,
i've not had any problems.  on the windows side, i can enter
'user.account' and it works.  ymmv...  you can do user mapping so that
'jdunlop' (from windows) becomes 'mgr.acct' for samba.  it is an extra
layer of complexity so give it some thought before proceeding.

once this samba-only password is set for the user, you can't look it up
(it's encrypted) so select the password with care.  oh -- and it's
case-sensitive too!

here's an example of how i typically set-up an account for samba:

[acct]
  comment = config access for MGR.ACCT
# grant access to the ACCT account tree
  path = /ACCT/
# require user validation by password
  guest ok = no
# allow read and write access
  write ok = yes
# create new files with rwxr--r-- permissions
  create mask = 0744
# only accept connections as mgr.acct
  valid users = mgr.acct
# check passwords against mgr.acct only
  user = mgr.acct
  only user = yes
# don't hide this share from network neighbourhood
  browseable = yes

(i only allow guest in the default samba areas)  hth      - d
