TYPO3.Flow

(by Fabian Guth)

Input fields with a name attribute with more than 64 characters are
ignored.

After hours of digging into the Flow3-Code i realized that its possibly a
wrong PHP setting. Following test case shows, that input fields with long
(more than 64 characters) name attributes are ignored.

I would really appreciate any hints on the bad setting variable!
I searched php.ini and http.conf without success.

Test Case:

 <?php echo print_r($_POST); ?>

<form action= "" method="post">  
 <input type="text"  
name="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"/>
 <input type="text"  
name="bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb"/>
 <input type="submit" value="Submit"/>
</form>

Renders following after submit (both fields are filled):

Array
(
   [bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb] => b
)

As a workaround i edited the Token
(F3\FLOW3\Security\Authentication\Token\UsernamePassword) to check for a
short array key. I hope there aren't any side effects.
I know that it's better to subclass it with a changed "updateCredentials"
method to preserve the patch at the next release.

As i use the default Linux PHP Package, i am afraid its a very common
setting.
