UI not alow add domain begin xn-- with error "host name with domain"
Manualy add to config file is working.
I guess the problem arises with the double minus sign “–”. That sequence does not match the validation regexp.
Anyway that sequence seems allowed by Wikipedia, at least
https://en.m.wikipedia.org/wiki/Hostname
Could you suggest any other reference to fix the bug?
IDN is standardized RFC 3490 - Internationalizing Domain Names in Applications (IDNA) with ACE prefix (xn–).
And from year 2009 allowed and now widely used for example in EU TLD Introduction of Internationalized Domain Names | MPO
Without repaired bug “add IDN domain record”
in to user interface is not usable in Europe. I mean the unusable for general users. IT technician can use a configuration files, but then litle becomes meaningless use NethServer.
Thank you for pointing it out and for the provided information! We can now record the bug on
