Authentication Failure

Postby gnu-stu on Tue Dec 28, 2010 5:03 pm

Hi All, I've installed LMDE from the live DVD onto my lenovo (IBM) ThinkPad R60 four times now and each time I attempt to log into my new installation I get an "Authentication Failure" message and fail to login. The live DVD seems to be working fine.
Anyone come across this problem before?

Cheers

No problem here
Is this the Latest LMDE release?
32 or 64 bit?

Did you run the media check? (Even though it boots to the desktop)

Hi caf4926,
It's the 64 bit version, 201012, I downloaded it two days ago (I think) when I saw it mentioned on Distrowatch.
I did do the md5sum check and it checked out OK ...

Authentication Failure means you are entering wrong password. Are you sure you are entering correct password?

Hi cecar,
that was my first thought after the first install, but after three more installs in which I set the same password I'm pretty confident that I'm typing the correct password.
Having said that I have rebooted into recovery mode and when prompted to "type in password or press ctrl+D to continue" at the command line, my password is accepted! weird!!

That is weird... Could it be something that there is something wrong with your keyboard setting when X starts?

What you could do after logging in into recovery mode..

passwd <your user name>

And set the password there..

Example for my username

passwd cecar

This sets a password for user cecar,

Just tried your suggestion cecar and got the following message;
Code: Select all
mint-debian~# passwd stuart
mint-debian~# passwd: user 'stuart' does not exist


I guess I could try using 'adduser' ... will 'adduser' put me in a default set of groups or do I need to define them manually?

Glad to be able to help.. :)
Just curious.. You must have another user named something else then?

Could you type in terminal
Code: Select all
ls /home

And post the output?

Since his password worked in recovery, I'm thinking that he may have a password with two of the same characters next to each other and is typing too fast. This sometimes negates the second letter if certain settings are in place in Keyboard Accessibilities. Bounce Key or Bouncy Key. I forgot what it was called.

To me it looked like he was trying to log in to a user that did not exist because terminal told him that user stuart was not to be found.

@cecar,
Code: Select all
stuart@mint-debian ~ $ ls -lsa /home/
total 12
4 drwxr-xr-x  3 root   root   4096 Dec 29 09:50 .
4 drwxr-xr-x 21 root   root   4096 Dec 27 20:28 ..
4 drwxr-xr-x 24 stuart stuart 4096 Dec 29 12:08 stuart


just the one entry ...
I'm gonna have to re-install again. Initially I had my hard drive all partitioned nicely and thought that maybe my partitioning scheme was screwy or something. At the moment I have one one huge partition + swap, not nice ...
