Liferay mail domain and Sign In

[Hiran Chaudhuri，修改在12 年前。]

It seems to me that whatever I enter in Portal Instances/Mail Domain, this value will be displayed in the sign-in page as default email address.
It also seems that this value prevents web browsers from directly inserting the user's credentials straight away.

What can I do to get browsers to fill in the form automatically?
I tried to set an empty mail domain, but Liferay does not allow that...

It defaults to your mail domain to simplify the login process for your local users.

I use the "remember me" checkbox to save my credentials.

Otherwise what you're asking for is not really possible; the server doesn't know who you are (you haven't logged in yet), and the browser has no reason to start populating form fields just cuz you land on a form page...

Understood. However I do not use cookies, which would be required for that solution.
However I want to use the browser builtin functionality.

Then how does this work on zillions of other sites?
I delete my cookies regularly, still the browser (whom I allow to store credentials) populates the fields as soon as the form/page is fully loaded.

edit: have a look at http://support.mozilla.com/en-US/kb/Form%20autocomplete and http://support.mozilla.com/en-US/kb/make-firefox-remember-usernames-and-passwords

The browser can store username/password combos. When you delete the cookies, it doesn't affect the username/password database.

When you use the browser functionality to save the username/password combo, the browser knows the page and id of the element that has the username and, when that page is rendered, can offer to pre-populate the values but only in empty fields.

In any case, this is all browser-triggered stuff. There is nothing in your page (or Liferay) which triggers this activity.

Exactly that is what I want to use.

But it seems that Liferay can prevent it. The browser does not fill in the Liferay Sign In form.
And I realized this is as long as such fields come pre-filled with some value. As soon as I remove that, Firefox offers the stored value.

So what can I do to make Liferay deliver an empty sign-in form without any mail domain in it?
