I'm not sure, but it could be (space required)

mike    ALL=(ALL) NOPASSWD: LXC

White space is optional there, so that shouldn't have any
effect.

The sudoers(5) man page says:

     White space between elements in a list as well as
     special syntactic characters in a User Specification
     (‘=’, ‘:’, ‘(’, ‘)’) is optional.

And FWIW, I have working rules with and without spaces¹.

My bet is on another rule interfering, due to user mike
being in group admin or sudo.  I've run into that myself.

¹ Because the rules were added at different times by
different people, not because I like to have messy white
space. ;)


       It is possible the sudoers file behaves in a "last line wins"
fashion. Move your lxc line to the end of the file and try again.


Defaults    env_reset
Defaults    mail_badpass
Defaults    secure_path="some_path"

# Cmnd alias specification
Cmnd_Alias LXC=/usr/bin/lxc

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo  ALL=(ALL:ALL) ALL

# User privilege specification
root   ALL=(ALL:ALL) ALL
mike   ALL=(ALL) NOPASSWD:LXC

----

sudoers.d is empty

launching an xterm from the cli then entering in the new xterm:

    lxc list

and I get a password prompt.  Absolutely no clue.
