    MULTI-USER ADD

    You must first create a text file before you can use this program
    properly. Each line is the record for one user account. See "Record
    Format" on page 4-13 for details on creating this file.

    The rest of this subsection describes the functionality of this
    window's fields and buttons.

    Fields

    This window contains the following fields:

    Filename of Accounts DB

    Use this field to specify which database file contains the user
    account information.

    Hostnames

    If you want to limit this user's access to specific hostnames within
    a pool, enter those hostnames in this field. If you are entering
    multiple entries, leave a blank between each entry. You can also use
    the arrow button to the right to select the available hosts from the
    current pool.

    Starting User ID Number

    If the Userid field (field #5) is left blank in any of the records,
    Enlighten will assign the first available (unique) Userid found
    (higher than the UID entered in this field). Click on the arrow
    button on the right to view the already assigned UserID's. A pop-up
    menu will appear with a current list of UserID's. Highlight the
    desired ID number and then click on the Apply button. Enlighten will
    automatically insert the starting Userid into the appropriate
    record.

    Default User Group

    If the GroupID Number field (field #6) is left blank in any of the
    records, Enlighten will use this field to assign those users a
    default Group Name. Click on the arrow button on the right to view a
    current list of User Groups. Highlight the desired entry in the
    pop-up menu and then click on the Apply button to make the
    selection. Enlighten will automatically insert the Group Name into
    the appropriate record.

    Default Home directory

    If the Home Directory field (field #7) is left blank in any of the
    records, Enlighten will use this field to assign those users a
    default Home directory. Use the full path name of the parent
    directory where all user's HOME directories will be created.

    If you specify a HOME directory which does not exist, Enlighten
    creates and initializes it. Enlighten initializes the HOME directory
    by executing the HOME directory initialization script
    $ENLIGHTEN/scripts/user.rc. This copies the initialization files
    (e.g., .profile and .cshrc) into the HOME directory. You can modify
    this script to perform other initialization procedures. These
    procedures are not done on the Windows NT platform. It will generate
    an error if the directory doesn't exist on a NT system.

    Windows style paths may also be entered, e.g. c:\users\charlie.
    However, this path will be converted to //c/users/charlie on any
    UNIX platform that is in the current hostnames selection field or
    in the current pool. This can be changed by entering two paths.
    The following examples show valid entries:

            c:\users\charlie|/home/charlie
            /home/charlie|c:\users\charlie
            /home/charlie|\users\charlie

    The symbol '|' is the pathname delimiter. Only one can occur in the
    field. Each individual pathname must not contain both '/' and '\'.
    A zero length pathname is an error condtion.

    You may also use macros in this field, see "User Account Macros" on
    page J-2 for more details.

    Default Startup Shell

    If the Shell field (field #8) is left blank in any of the records,
    Enlighten will use this field to assign those users a default shell.
    Click on the arrow button on the right to view a current list of
    shells. Highlight the desired entry in the pop-up menu and then
    click on the Apply button to make the selection. Enlighten will
    automatically insert the shell name into the appropriate record.

    Mail Alias

    This field specifies the default mail alias the account will use. An
    alias designates a short name as the substitute for the full
    pathname for a particular user or group. You may also use macros in
    this field, see "User Account Macros" on page J-2 for more details.

    Mail Lists

    This field specifies which mailing lists will be updated to include
    this user. A mail list defines a group of people under one alias, so
    sending mail to that alias will distribute a copy everyone on that
    list. Click on the arrow button for a pick list of defined Mail
    Lists.

    Default Password Configuration

    When a user is created in UNIX, he or she must be assigned a
    password. If the password field (field #9) is left blank in the
    database record, the system must be told which method to use to
    create a password. Choose one of the following options as the
    default:

    + Add all users with the same initial password (the default)
    + Generate random password for each user
    + Password same as user name

    Initial Password

    Use this field if you choose to add all users with the same initial
    password. Enter the password to be assigned to all the user accounts
    created from this process. Remember to check later and make sure
    each new user has changed his initial password. You may also use
    macros in this field, see "User Account Macros" on page J-2 for more
    details.

    Password to expire

    For systems that support password aging, this optional field
    contains the time when the password will expire. Once a password has
    expired, the system will force the user to change their password the
    next time they login to the system.

    If this field is left blank, the appropriate default parameter will
    be used. If no default is set in the User Add window (when you're
    adding a user), password aging will be turned off for that user. For
    more details.

    See "TIME FORMATS" at bottom of help page.

    Span between changes

    In conjunction with the Expires field, this field defines the
    minimum period of time which needs to elapse before the user can
    change his or her password. You can, however, change the user's
    password at any time via Enlighten.

    See "TIME FORMATS" at bottom of help page.

    Buttons

    This window contains the following buttons.

    Add

    Once you've entered the relevant information, click on the Add
    button to start the user account creation process. Enlighten first
    checks all field entries are valid and then starts creating the new
    user accounts.

    Enlighten will then output a list of generated passwords after all
    the accounts have been created. Click on the Print button if you
    want to print the list.

    Clear Fields

    Click on this button to clear the existing choices in all fields.

    Template

    Click on this button for a pick list of defined New User Templates.
    You can use one of this templates to populate default values in the
    new user's account, make any necessary changes, and then Add the
    user. Only those field which are currently blank (in the Create New
    User Account window) will be initialized from your selected
    template.

    Close

    Click on this button to discard any changes and close the window.

    USER ACCOUNT MACROS

    You can use macros to help initialize the form fields when you
    create a User Account. You can enter these macros manually. Or you
    can have them fill (some of) the form fields automatically by first
    defining them in a New User Template and using that template when
    you create the user account.

    The following types of fields accept macros in these two windows:

    + Login Name
    + Home dir.
    + Password
    + Mail Alias

    For working examples, see "Macro Name" on page J-3.

    Format

    A macro has the following format:

        %<Modifiers><Macro Name>

    Modifiers

    <Modifiers> are optional (you can define them multiple times). You
    can use the <Modifiers> to specify only specific parts of the field,
    such as the first letter of the field, or to manipulate and convert
    the given input.

    A modifier has the following format:


    [<Converter><Range>]

    where <Converter> is one or more of the following characters:

        l - Convert the resulting string to lower case
        L - Same as `l'
        u - Convert the resulting string to upper case
        U - Same as `u'
        s - Do not include SPACEs
        _ - Replace SPACEs with underscores (_)

    and the <Range> applies to the complete string in the field (by
    default). Or you can apply a range to a specific word in the input
    string.

    Consequently, a <Range> has the following format:

        $<word number><Character Range>

    where <word number> shows the word's sequence in the string (this is
    optional). The first word would be addressed as $1, the second word
    as $2, and so on. You can also use $0 to address the first word.

    <Character Range> is a comma separated list of character ranges in
    the form. If you specify a <word number>, you must first use a comma
    (`,') in the range list.

    The character range itself has the following format:

        <start char>-<end char>

    where <start char> and <end char> are character numbers. You can
    omit one end of the range to signify the "start of string" and "end
    of string" respectively. Ranges which go beyond the end of the
    string are truncated to match the string.

    Macro Name

    <Macro Name> is one of the following characters:

        g - replace with the users' GID
        u - replace with the users' UID
        G - replace with the users' group name
        U - replace with the users' login name (username)
        R - replace with data from the users' Real Name field
        O - replace with date from the users' Office field
        T - replace with date from the users' Telephone field

    Examples

    These definitions make more sense when they are viewed as examples.
    Assume for the following example, the following data is true:

        Real Name: Thomas Kraus
        Login Name: tmk
        UID: 302

    You could then define the following macros and see the following
    substitutions.

        Field Name   Macro               Value
        -------------------------------------------
        Home Dir     /home/%U           /home/tmk
        Password     %U-%u              tmk-302
        Mail Alias   %[u$1]R_%[u$2]R    THOMAS_KRAUS
        Login Name   %[l$1,1][l$2,-6]   tkraus

    Some explanations:

    /home/%U Create the directory /home/<login name>

    %U-%u Get the User name and add the UID (separated by a dash)

    %[u$1]R_%[u$2]R Get the first word of the users' real name and add
    the second word of the user's real name (separated by an
    underscore). Convert both strings to upper case.

    %[l$1,1][l$3,-6]R Take the first letter of the users first name and
    the first six letters of the users' last name. Convert both strings
    to lower case.


    Record Format

    The format for each record in the text file is:

        Field # Description        Comment

         1      Login Name         Mandatory
         2      User Real Name     Mandatory
         3      Office             Optional
         4      Telephone          Optional
         5      Userid Number      Optional
         6      Groupid Number     Optional
         7      Home Directory     Optional
         8      Shell              Optional
         9      Password           Optional

    Each record (line) in the file represents one user. Each user can
    have up to nine fields in the record. Use a comma (,) to separate
    each field specified. Each record is terminated with a carriage
    return (<CR>). There is no limit to the amount of records you can
    specify in the file.

    The following example sets the account details for five people.

        fred,The Fredster
        barney,The Barnarama,Head office
        wilma,Wilma Fraglerock,,233-7625
        betty,Betty Boomrock,,,401,other
        bambam,Boom,,,403,other,/usr/bambam,/bin/sh,bedrock


    TIME FORMATS

    There are several fields throughout the Enlighten product where you
    can specify a date/time format. For each of these fields, you can
    specify the date and/or time period in two ways: absolutely or
    relatively.

    The first is as a static period, where the period entered is the
    absolute period used in the search. This is the only way to search
    for a combined date/time format. To look for a file created since
    May 10, 1996 at 12 noon, you could use the entry: May 10 96 at
    12:00.

    The second is a relative period, where the period entered is set
    against the current system clock time and then applied during the
    search. This is strictly a time OR date format, e.g., 2 seconds or 1
    month. To find users who have been logged in during the last three
    days, you could use the entry: 3 days.

    Either way, the format is case-insensitive. For example, you could
    use JAN, Jan, or jan as the abbreviation for the month of January.
    This appendix shows all the BNF time measurements in initial caps
    (e.g., Jan or January, 2 Sec or 2 Seconds, etc.).

    Some typical uses of the static format in a Date search field are:

    Absolute: 15 1996 (defaults to the current month)

        Jan 1 97
        July 4 (defaults to the current year)

    Some additional uses of the absolute format in a Time search field
    are:

        June 15 at 3 PM (defaults to the current year)
        June 16 at 2AM (defaults to the current year)
        June 17 96 at 15:31
        18 at 9:31:14 AM (defaults to current month AND year)

    Some typical uses of the relative format in a Date search field are:

        Relative: 1 second

        5 Min
        1 day
        2 weeks
        1 Year

    The rest of this appendix defines the time formats you can use
    whenever you fill in a date and/or time field.
