Hi,
I was working on this problem: https://bugzilla.sudo.ws/show_bug.cgi?id=748
The fix seems OK, but I noticed that the option sudoers_locale probably
does not work as described in man pages: Locale to use when parsing the sudoers file,
logging commands, and sending email. Note that changing the locale may affect how
sudoers is interpreted. Defaults to “C”.
When these default values are used in sudoers file:
Defaults sudoers_locale = cs_CZ.UTF-8
Defaults passwd_timeout = 0,1
sudo returns this error:
>>> /etc/sudoers: syntax error near line 58 <<<
sudo: parse error in /etc/sudoers near line 58
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
When I set 'cs_CZ.UTF-8' locale to parse the file, '1,0' should be a valid value.
The problem seems to be in a grammar which is used by the parser, I'm not sure if
I am free to change it.
Another question is that if '1,0' even passed through the parser, the position of
'Defaults sudoers_locale = cs_CZ.UTF-8' in the sudoers file must matter, because
Defaults are loaded from the top to the bottom of the file, so :
Defaults sudoers_locale = cs_CZ.UTF-8
Defaults passwd_timeout = 0,1
teoretically would pass but :
Defaults passwd_timeout = 0,1
Defaults sudoers_locale = cs_CZ.UTF-8
would not. Shouldn't it be mentioned in the documentation that the position of 'sudoers_locale'
matters or even that it must be placed to the beginning of the sudoers file so as it would behave
according to the man pages description mentioned above? I wasn't sure about it, that's why I'm asking.
