[SOLVED] Authentication failure for root logins (Fedora 12)

JustOnePixel · 01-20-2010, 11:59 AM

Hey everyone,

I just got Fedora 12, and I used su root to change the bin ownership to my primary developer account. For some reason, though, all subsequent attempts to log in as root have had authentication failure, be it through su or through the startup login screen. This does NOT occur for adminstrator tools such as Groups and Users. Any ideas why this might be happening?

root login in fedora AND Gnome have been disabled on BOTH for the GUI
login as a normal user and use "su -" in the terminal

fedora DOSE need you to use " su -" and NOT " su " to use the root account .This is VERY well documented in the fedora docs

Don't change that ownership. If your 'primary dev' acct needs access, add that to his $PATH and/or add him to the relevant group.
You'll want this to reset the perms correctly: http://www.cyberciti.biz/tips/reset-...ermission.html

Hey everyone,

I've tried su -, and I'm still getting denied access with the right password. Any thoughts?

What exactly did you do , to do this . Please post what you did.

I did the following to change permissions:

Code:

su root  //Now I know that was a bad move!
chmod 775 /bin

The plot thickens, though: I reformatted the computer, and logged in as root again (this was before I posted the question.) This time, I didn't edit anything (just

Code:

su

'd into the computer), and then logged out. Interestingly, I was locked out of both

Code:

su root

and

Code:

su -

. What should I do to correct this, short of rebooting the whole machine?

if you did this " chmod 775 /bin "
then you will need to reinstall fedora 12
you FUBAR'ed the operating system

Why did you do "chmod 775 /bin"? What were you trying to achieve?

Bahaha, oops. Well, that was silly.

@Evo2: I was trying to allow myself to write to /bin because I was having trouble installing to it. So that won't be happening again...

Anyway, thanks everyone for helping out a true moron. I really appreciate it!
