    Fedora Core 2 : Authentication Failed


    Sorry to repost this, but my original post disappeared before I could
    get a solution.
    My system flat-out refuses to allow anything to login.
    I can get limited access through single-user mode, but I can't figure
    out how to fix the problem from there. The exact problem:
    -Single-user mode:
    >su
    Incorrect Password

    >passwd
    Changing password for root...
    passwd: Unknown Module

    su immediately shows "Incorrect Password' without allowing me to enter a password, and passwd shows "Changing password for root..." for a few seconds before outputing the error.

    -Multi-user (runlevel 3):
    Regardless of what is entered at the login prompt, it flashes "Incorrect Login" without giving me the option to enter a password

    -Multi-user GUI (runlevel 5)
    Again, no matter what is entered in the login field, it brings up a dialog
    which simply says "Authentication Failed" without allowing me to enter
    a password.

    there was a problem with the database and the past 4 days of post were lost (see the news forum) Do you have anything that you cant afford to lose? I would reommend re installing, it seems like you botched the install a bit, redownlaod and burn the ISO's then check the md5sums.

    Sorry, I didn't check the news page.
    It wasn't the installation, the system has been working fine for about a month, and I can't think of anything I did that would make a problem.
    I can afford to reinstall it, but I'd like to avoid it if possible.

    I fixed the problem myself.
    Apparently, the PAM module got damaged somehow,
    so I uninstalled and reinstalled the RPM from the FC2
    distro disk, and now things work almost perfectly.
    The problem now is that if I set the default runlevel
    in /etc/inittab to 5, the boot process hangs on
    "allocating swap space." Other values (excluding 0 & 6
    of course) cause a prompt to appear during boot asking
    which runlevel to use. I figure the inittab file got damaged,
    as the boot process displayed an error about a missing
    process field in inittab, but i have no idea what could be wrong.
    Any help would be apreciated.
