Ipad auto-capitalization of username

[McDermott, Michael]

Hello List,

I haven't seen anything on the user list about this, but our Ipad/Iphone users are complaining that "Shib" capitalizes their case sensitive username when they login and wonder how to "fix" Shib.

Clearly this is a client issue, but the "fix" I've found is to add the html element that directs clients not to auto capitalize.  

In the login.jsp, change the input field from something like:

<input name="j_username" type="text"  />

to

<input name="j_username" type="text" autocapitalize="off"  />

I'm wondering if others are doing the same thing, and if there are any problems with this approach.  If not, then perhaps it could be added in a future release of the IdP.

You don't mention what the actual problem is (authentication failing?
JAAS?) but I lookup usernames entered on the web from LDAP (uid),
which is case-preserving (keeps and returns case as stored, which is
consistently lowercase here) but has case-insensitive matching
rules. That way usernames entered on the web are normalized "for
free". Don't know if that helps or not.

Kerberos would fail certainly unless you add code to lower case the
principal (assuming you use lower case principals).

I have code like that in mine, but this is a convenient trick to fix the
problem.

That would be something I'd be fine adding to the default login JSP
page if you wanted to file a JIRA request for it.

Hello,

since that's a non-standard attribute (causing validation of the page
to fail), I would recommend to not add it to the default login page.

Bernd

Chad,

I'd be happy to put in a JIRA ticket, 

Bernd, before I do, other than a validation to fail, what error is it likely to cause?  Have you any experience, anecdotes, or evidence that it impacts screen readers for the visually impaired or something analogous?

A known issue with usability outweighs correctness for its own sake in my estimation, but I know little about what additional issues may arise and a brief wrangle with Google did not yield any issues.

I fully agree with Bernd that the project should not be changing
defaults to include non-standard/non-validating HTML esp. when it's
trivial to add this to your own login.jsp during branding/customization.

[Chad La Joie]

The *example* login page doesn't claim conformance to any of the dozens of HTML/XHTML versions out there, so it's not technically possible for any of it's pages to be schema/DTD invalid. I don't even know which schema/DTD I'd pick if I had to.

Conversely, to your point Peter, if you care about validation against a particular HTML/XHTML schema/DTDs it's trivial to remove that attribute when creating your real login page from the shipped example.

A proper way to force the text lowercase on the client would be to have some javascript - fairly trivial.

FWIW, we made this change to our login page over a year ago, and haven't
heard any negative side effects; mostly, people were thrilled they no
longer had issues with iPads and Androids.

A little after that, we also added:
<meta name="viewport" content="width=device-width" />

This helped our customized login page. I'm not sure if it will improve
the usability of the default/sample login page, though, as it is much
wider than our login page is.

Hope this helps,

There is "proper" way to do any of this stuff. There is only the way that works best for you in your environment.

+1

[McDermott, Michael]

Not seeing any objections other than it might upset validations, I'll post it to Jira and the core team can debate.
