[Solved] sudo not accepting my password anymore all of a sudden

So, as the title says, apparently sudo doesn't like any of my passwords anymore. Many times I've tried to change it and when I want to run a command through sudo it just gives me 3 attempts (all of which fail) and then gives up.
I have tried the easiest possible passwords, such as 'ciao', maybe thinking that it could have been a different charset problem, but it failed as well.

This is my sudoers file

## sudoers file.
##
## This file MUST be edited with the 'visudo' command as root.
## Failure to use 'visudo' may result in syntax or file permission errors
## that prevent sudo from running.
##
## See the sudoers man page for the details on how to write a sudoers file.
##

##
## Host alias specification
##
## Groups of machines. These may include host names (optionally with wildcards),
## IP addresses, network numbers or netgroups.
# Host_Alias	WEBSERVERS = www1, www2, www3

##
## User alias specification
##
## Groups of users.  These may consist of user names, uids, Unix groups,
## or netgroups.
# User_Alias	ADMINS = millert, dowdy, mikef

##
## Cmnd alias specification
##
## Groups of commands.  Often used to group related commands together.
# Cmnd_Alias	PROCESSES = /usr/bin/nice, /bin/kill, /usr/bin/renice, \
# 			    /usr/bin/pkill, /usr/bin/top

##
## Defaults specification
##
## You may wish to keep some of the following environment variables
## when running commands via sudo.
##
## Locale settings
# Defaults env_keep += "LANG LANGUAGE LINGUAS LC_* _XKB_CHARSET"
##
## Run X applications through sudo; HOME is used to find the
## .Xauthority file.  Note that other programs use HOME to find   
## configuration files and this may lead to privilege escalation!
 Defaults env_keep += "HOME"
##
## X11 resource path settings
 Defaults env_keep += "XAPPLRESDIR XFILESEARCHPATH XUSERFILESEARCHPATH"
##
## Desktop path settings
 Defaults env_keep += "QTDIR KDEDIR"
##
## Allow sudo-run commands to inherit the callers' ConsoleKit session
 Defaults env_keep += "XDG_SESSION_COOKIE"
##
## Uncomment to enable special input methods.  Care should be taken as
## this may allow users to subvert the command being run via sudo.
# Defaults env_keep += "XMODIFIERS GTK_IM_MODULE QT_IM_MODULE QT_IM_SWITCHER"
##
## Uncomment to enable logging of a command's output, except for
## sudoreplay and reboot.  Use sudoreplay to play back logged sessions.
# Defaults log_output
# Defaults!/usr/bin/sudoreplay !log_output
# Defaults!/usr/local/bin/sudoreplay !log_output
# Defaults!/sbin/reboot !log_output
Defaults insults
##
## Runas alias specification
##

##
## User privilege specification
##
root ALL=(ALL) ALL
freakazoid ALL=(ALL) ALL

## Uncomment to allow members of group wheel to execute any command
 %wheel ALL=(ALL) ALL

## Same thing without a password
# %wheel ALL=(ALL) NOPASSWD: ALL

## Uncomment to allow members of group sudo to execute any command
# %sudo	ALL=(ALL) ALL

## Uncomment to allow any user to run sudo if they know the password
## of the user they are running the command as (root by default).
# Defaults targetpw  # Ask for the password of the target user
# ALL ALL=(ALL) ALL  # WARNING: only use this together with 'Defaults targetpw'

## Read drop-in files from /etc/sudoers.d
## (the '#' here does not indicate a comment)
#includedir /etc/sudoers.d

And, for what it's worth, the root and user password are the same.
Many thanks in advance for your patience.

Many thanks in advance for your patience.

Which basically means

su -c

should fit your needs anyway

abraxas88,

check the permissions of the /etc/sudoers.

should be:

-r--r----- 1 root root 1,1K Abr  1 13:29 /etc/sudoers

Okay, that's it. I always check whether there are other threads about it, but I wasn't aware that pam would have broken sudo. Apologies and thank you. Marked as solved.
