Make `mail` attribute optional

[n-peugnet]

Currently, mail attribute seems to be required. Would it be possible to make it optional and let the user enter an email when creating the account ?

I just made a test by not providing the email address in the Controller. The LDAP connection modal asked me to type an Email address that later need to be verified, which is what I would expect in this case.
