[EXTERNAL] Re: change case to Title case in IdP

[O'Quinn, Dennis]

Hi, can someone tell me how to just get the returned NameID (i.e., at the SP) converted to lowercase?

I have no control over how the data is stored or presented to me, it comes in uppercase, and, I just need to change it to lowercase before passing it off to the application.

Will the “<AttributeResolver type="LowerCase" source="NameID" />” directive do that for me (running Shibboleth 2.6.1).

Thanks, Dennis

That's where you'd need to fix it, in the source system.

You can't. There's no algorithm in the world that can get the case
correct in all, well, cases. There are too many cultural and regional
conventions involved (MacBla, Macbla, Mc Bla, De La Foo, De la Foo,
van der Foo, Van Foo, etc.pp.) -- ignoring the case (ha!) or non-latin
script completely for now -- and people are somewhat picky when it
comes to messing up their names.
(They're probably used to the specific messing up you've done so far
in ALL CAPS as they realize that's not how the name is supposed to be
spelled.)

So save yourself that trouble of implementing a "quick fix" downstream
that doesn't in fact fix anything, and start recording case properly
at the source systems.
