I noticed that a group can be used as account as well, but without any password!
HFS will prevent anyone from loggin in with a group name
a)create an account with no password
b)Attribute the rights of access for a directory for this account only
c)convert this account as a group
d) you can go in the folder with the account(group) name and blank password
e) if you uncheck the group for this account, give it a password , and convert it as group
f) password box is masked
(don't forget to save every time
f) you can now go in the folder with the group name and the new password ( leave blank and you can't log)
end; // saveAccountProperties
the password is saving every time you save an account, when you change an account to a group , the old password is not cleared.
sorry maverick, but I agree the other man
