Manager error not displayed
If there is an encoding error in conf, manager do not save conf but no error message is displayed.
Found this in error log: mod_fcgid: stderr: malformed or illegal unicode character in string [\xe9d\xe9ration d], cannot convert to JSON at /usr/share/perl5/Lemonldap/NG/Common/PSGI.pm line 105.
Maybe this kind of error could be handled to display a clean error message
