Trailing dot autoremove

[1Dragoon]

Given RFC 3546 stipulates that the trailing dot should never be present in a domain name: https://datatracker.ietf.org/doc/html/rfc3546#section-3.1

Could we either automatically detect and remove the trailing dot from domain names passed to native-tls, or have the error message produced show what the expected name(s) was vs what was found?

FWIW here's where I ran into this issue:

inejge/ldap3#84

May or may not be in scope for this project, just wanted to at least bring up the issue.

This crate does not interact with rustls.

sorry accidentally wrote rustls but meant native-tls

native-tls directly exposes the errors returned by the underlying TLS library (e.g. OpenSSL). If you want a more descriptive error, you would probably need to ask there.
