    How to disable annoying authentication prompt?


    Hi,

    I would like to disable the most annoying authentication prompt in Suse
    Linux Enterprise. I have tried all the options under Security Center And
    Hardening as well as User and Group Management. Also Encription and
    Keyrings. The annoying prompt appears when I try to open e.g. Yast or
    similar.

    If there's a simple way to disable all authentication, that would be
    great.

    Please help, it's driving me nuts. Thanks in advance.

    Hi
    It's called security You can use the sudoers file to add
    applications to not require your 'root' user password.

    Thank you for the reply. However, if you could find it in your heart to
    explain where this file is and what I should do with it, I,d be most
    grateful. And as for security, imagine if you had a car that asked you
    for a password each time you wanted to use the turn signal, it would
    suck pretty bad now, wouldn,t it?

    Google finds it pretty quickly: /etc/sudoers

    Yes, but it'd also be pretty bad if the turn signal had anywhere near
    the implication to the car's functionality as running something as
    'root' does. A better comparison would be starting the car, or opening
    the car door, both which require a key (root password). I am sure you
    will find that the vast majority of commands on your system do NOT
    require the root password.

    Good luck.

    Hi
    But a turn signal may not compromise the car, now if you have a vehicle
    with one of those keypads for entry, would you put a sticky note on the
    window with the password?

    Anyway, we digress, have a read of these;
    http://en.opensuse.org/SDB:Administer_with_sudo
    http://en.opensuse.org/SDB:Login_as_root

    You can customize the YaST commands via launching the individual
    modules and add specific ones your wanting rather than just YaST in
    general. The other one maybe look at installing web YaST and open with
    your browser, web YaST is still in it's early stages, but I think will
    do the tasks your wanting (plus you can save the password in the
    browser cache )

    Hi, thank you again for the answers. I have managed to locate the
    sudoers file and have even found instructions on how to disable the ****
    thing, but unfortunately, I cannot open it. The system says it doesn,t
    recognize the file type or something. I don,t know, I,m pretty exhausted
    by now. I think I might just install Windows, despite the hassle of
    installing drivers. Well, thanks.

    How did you try to open it? This should pretty easy as it is a plain
    old boring text file:

    sudo vi /etc/sudoers
    #enter the root password when prompted

    Good luck.

    Are you going to install Windows XP? Because that defaults to you
    running with Administrator rights which means that you, or *any*
    software you run (knowingly or unknowingly), is free to change any part
    of the operating system you like without anything asking you 'are you
    sure?'. This is very, very convenient for the user in the short term but
    it is a travesty from a security point of view and can create massive
    inconvenience for the user when their system becomes full of viruses, or
    they accidentally trash part of the OS and render the machine
    un-bootable, because of the total lack of any 'are you sure?' or
    additional authentication being required to make changes to the OS.

    Vista and 7 both prompt you before making system level changes, which
    is the behaviour you're complaining about in SLED. Microsoft introduced
    that for a reason and that reason is security. Mac OS X also puts up an
    authentication prompt when you're trying to change something at the OS
    level. It is a *good* thing.

    Linux clearly separates the regular users from the user which can
    change parts of the operating system (root). A regular user can only
    change things that relate to that user. The root user can change
    *anything*. So normally you run as a regular user and all you can mess
    up is your own environment. If you want to make changes to the operating
    system itself, you need to do that as root. (Or as a user which you have
    given sudo rights as Malcolm suggested, but will still mean a prompt for
    authentication.)

    If you really think about it, would you honestly say that having
    uncontrolled access to the entire operating system all the time is
    better than you being asked to enter a password before you make changes
    to it? (If your answer is yes, you need to think about it more )

    Jesus tapdancing Christ!!! Why are you acting like a retarded child had
    asked you where to buy some heroin? First of all, it's just a f+cking
    computer. Mine, not yours, not the Pope's. Not storing any nuclear
    missile plans or nude pictures of Mahmoud Ahmadinejad on the hard drive.
    There's not going to be a tsunami if I delete something by accident.
    Just an ordinary crappy laptop made by poor Chinese people.

    Second of all, you will probably think that it's unbelievable that I
    have had that Windows XP you fear so much, for years and had NEVER, not
    once, messed anything up by accident. "Wow, you must be a f+cking brain
    mutated genius, how the f+ck did you manage that?". I hear you say.
    Well, I have this amazing ability not to mess around with stuff I don't
    need. So there was never, not once, any need for a stupid password.

    So please understand that I have read and understood the warning,and if
    I end up in Linux hell for disabling the **** authentication, it's on my
    soul,not yours. Here, I'll even give you a written disclaimer:

    I hereby declare, of sound mind and reason and with no pressure from
    anybody, that I have understood and acknowledged that disabling the
    stupid authentication in Suse Linux or any other Linux distribution will
    surely bring about the apocalypse, whereupon the black plague will
    return and Satan and all his armies will arise from hell to torture us,
    and our children will walk backwards, and the four horsemen will pillage
    the land saying "Why did he disable the password?", and the Lord will
    smite us with his smiting thingy, and there will be no more porn on the
    Internet. Amen.

    Now will you please, please, please tell me how to edit the f+cking
    sudoers file?

    Is it possible to you to log as root, then edit this file, then switch
    back to your user session ? It will be easier to edit than using vi
    editor.

    Otherwise, try this with a terminal (xterm or gnome terminal) the
    following commands :
    xhost +
    su
    [prompt : type the administrator/root password]
    gedit /etc/sudoers

    You should be able to edit the file.

    Regards,

    Arnaud
