sudo

Hello,
I'm having problem with my sudo. It always denies my attempt as if my password was incorrect. There is a clear time difference when I write correct and incorrect password (sudo always lags for a second when user enters wrong password).

My distribution is Arch linux.

I installed fresh version of sudo, problem can be reproduced.

Code:

[root@sigma /]# sudo -V
Sudo version 1.8.5p2
...
[root@sigma /]# ls -l /etc/sudoers
-r--r----- 1 root root 2849 May 31 13:37 /etc/sudoers

If /etc/sudoers is configured to forbid me usage of sudo, it asks me for password, but never accepts authentication.

Behavior is same when I allow sudo usage for wheel group and add myself to wheel group.

Code:

[root@sigma /]# cat /etc/sudoers|grep wheel
## Uncomment to allow members of group wheel to execute any command
%wheel ALL=(ALL) ALL
# %wheel ALL=(ALL) NOPASSWD: ALL
[root@sigma /]# su skyer
[skyer@sigma /]$ groups
wheel audio users wireshark skyer

I can log in using 'login' normally. (login, the program for standard log ins).

If I allow access for wheel without password, it seems to work.

I have no idea where the problem could be,
thank you for your help.

AFAIK, you have two options right now.

1. Set a new password for your user account.

2. Create a new user group and add your user account to it. Then use 'visudo' to add it to the config file.

Furthermore, you should note that any changes to sudo usually don't take affect until you log out and log back in again. When in doubt, restart your computer. If that doesn't work, then it may not be just sudo that has a problem.
