Cookie issue with username length

Stéphane Laurière
Hi everybody,

I have this issue with usernames: it appears that too long logins
prevent users from logging in. What is the actual limit for login names,
and is there a way to extend it?

As a test I have registered on xwiki.org a user with a username having
100 characters, and they cannot login indeed.

Locally I see the user is correctly authentified, but then there's a
problem with the cookie. Here's the trace I get:
==============
!remember-me cookie validation hash mismatch!
!remember-me cookie has been tampered with!
!remember-me cookie is being deleted!
==============

That's a problem for me as my logins are based on the email address, and
some have a length of 100 characters.


Stéphane
