FreeDNS user ID capital letter dialog

[Navid200]

If you create a new FreeDNS account and choose a user ID that has capital letters in it, FreeDNS will not inform you and approves your account. However, your user ID will be converted to all lowercase letters.

If you attempt to log into FreeDNS with the original user ID containing capital letters, your login will be rejected.

If you log into FreeDNS, you can see your approved user ID, which is identical to the one you entered with all letters converted to lowercase.

This PR informs the user if they enter a user ID containing capital letters with the following dialog:

Thanks to @justinthomas for reporting this here: #32.

Excellent, that message would've saved me some time and will certainly help prevent someone else from the same difficulty.

can't we just lowercase whatever they enter?

@jamorham If everything had been done correctly, by FreeDNS, they would inform a user that capital letters in the userID will be changed to lower case as soon as the user entered such in the form.
But, FreeDNS does not do that.
Instead, they change the selected accepted user ID and change it all to lower case.

We can be complicit with the FreeDNS behavior and also hide things from the user and just convert the user ID to lower case.

I suggested that we did not do that. Instead we are informing the user what has happened. That if they log into FreeDNS and pay attention, they can see that their user ID does not contain capital letters.

But, the short answer to your question is, yes, we can.

@jamorham The fact that the user has entered a user ID containing capital letters shows that the user is not aware their user ID has been changed.
Alternatively, it may just suggest that the user has made a typo and entered their user ID incorrectly.

Either way, FreeDNS changes the selected user ID by the user without clearly notifying them.
This is the email I received:

I have marked the only sign that my chosen user ID has been changed by a red enclosing rectangle. That's all. How likely is it that the user will pay attention to that? I didn't.
