User guide
Logging on
User identification (id)
As far as FileStore is concerned, the people that use it are identified by their
user identification when they log on. In this manual we abbreviate this to
user id. Typically, each id owns a directory with the same name, contained
within the root directory.
The id used to log on tells FileStore which directory the user owns and thus
which files they can use and change and where to put files they create. Thus,
in the above example, the user EDP owns the directory named EDP and all
that it contains.
File ownership
In general, users can use, change and delete any files that they own, but can
only use files owned by someone else — they cannot change or delete them.
(But see Security and
access
in Chapter 3.)

When a user attempts to log on, FileStore checks for the user id they type in
a file called the password file. This is a file created by FileStore but
maintained by you that contains the user ids and passwords of all users that
will be allowed to use FileStore.
FileStore looks for the password file on its 'leftmost' disc. This is the hard
disc, if one is being used, otherwise the disc in the lefthand drive if it is being
used, otherwise the disc in the righthand drive.
Mistaken password
If the user id typed is not in the password file, users will receive the error
message
User not known.
Try again.
If the user id is in the password file but the user has not typed the password
required to use that id, they will receive the error message
wrong password.
If the user id is in the password file and the user has typed the correct
password, they will be logged on as that id.
User directory
FileStore will then look for the user directory corresponding to the id, again
searching from the lefthand disc. If it finds the user directory, the user will be
logged on to that disc with that as the current directory. If it doesn't find the
correct user directory, the user will be left in the root directory ($) of the first
disc searched.
