Hello everyone.
I am writing here (hopefully it's the right list for the topic) to ask about IDN (Internationalized Domain Names) support in OpenLDAP and LDAP in general.
I'd think it's not relevant for LDAP, because:
- DNS originally was ASCII based with only a limited set of characters allowed,
Strictly speaking: Nope.
See definition of RDATA:
https://datatracker.ietf.org/doc/html/rfc1035#section-4.1.3
Anyway use of DNS RRs is specific to application protocols. Thus broad statements like yours are always wrong.
while LDAP allows UTF-8, a wider character set. So basically just use the name you like.
Also this general statement is wrong.
- IDN support (AFAIK) just translates "special characters" to ASCII
when querying the servers, and the ASCII response is translated back.
This is only applicable when resolving host names or MX RRs.
Not needed for LDAP.
Are you actually overseeing what you're talking about? What's "needed for LDAP" depends on how certain LDAP clients (e.g. MTAs) make use of it. And that's why some people are writing specifications.
Ciao, Michael.
