Email matching for invitations is case-sensitive

[abliss]

Description

When inviting someone to a channel by email, the email is matched case-sensitively. It should be case insensitive.

Steps to reproduce

• Create a private channel
• Invite with email a new user who has never used matrix. Use a capital letter in the email address, like User@example.com
• The new user receives the email and tries to log in, but uses an all-lowerecase email, like user@example.com

Expected: User should be able to log in.
Actual : User is denied with a message like: "This invite to this room was sent to User@example.com which is not associated with your account"

Version information

• Homeserver: matrix.org (using the riot.im frontend)

I think this issue is already fixed, as I cannot reproduce it: I invited my other email starting with capital letter, during process of registration I used all lowercase and it worked like a charm.

@MadLittleMods care to take a look and close this issue if this is no longer a problem? I'd submit a fix, but I cannot reproduce it on matrix.org

I invited my other email starting with capital letter, during process of registration I used all lowercase and it worked like a charm.

To clarify:

• were you able to register a new account using the all-lowercase address?
• when logged in to that new account, did the client show the invite you made before?

[Vetchu]

Yes, I followed this procedure:

• from exisiting account I invited User@domain.com
• I got an email on user@domain.com
• I created account user@domain.com
• on first login, I was shown the prompt to join room and joined the room without problem

I think this reproduces the thinking presented in OP, and it does not produce an error anymore. I can reproduce with screenshots if needed.

That's fine, I was just checking what "worked like a charm".

Given that there have been fixes in the area let's close this. Can reopen if it turns out we missed something.
