Special characters in username

[rosali]

Assume that "über@über.net" is a valid and existing user. If I try to login with this user, I a valid login in my MTA logs (hmailserver). RoundCube Login fails with the message "Session invalid or expired".

The reason is that RoundCube creates a user in users table with an empty username field.

It is a serious problem for me, because I urgently need support for IDNA domains!

über@über.net is not a valid email address. While the domain-part may be an IDN, the local part is still defined by RFC 2822, which only allows 7Bit-ASCII characters in the local part.

See

Yes you are right, but valid@über.net cause same problems either.

[lukasGraf]

You might want to try using the Ascii compatible encoded form as a workaround, until IDNs are implemented in RoundCube: "valid@…"

D'oh. That was supposed to be valid (at) xn--ber-goa.net. Sorry for cluttering up this bugreport.

Replying to lukasGraf:

Did it this way and it works.

Real Name/Domain?: IDN encoded
Alias: valid@über.net

Nethertheless RoundCube should never create users in users table with empty username field.

And it is still not perfect because identiy etc. do show up encoded.
