[Contrib: Evaluation System] selecting "login" with an ad hoc group of recipients

[Adam Marshall]

we've discovered a problem if one selects "Login to Sakai" and then use an ad hoc group which contains email addresses which do not relate to a  sakai account.

What happens is that these users receive an email with a link but are challenged for a login - since they don't have an account they get stuck.

What is the intention here?

1/ should such users have accounts created on the fly so that when they attempt to fill in the survey they can actually log in, or,

2/ should the system actually prevent people without accounts being added to the ad hoc group if "login to Sakai" has been selected.

we're happy to fix this bug but would like to know what the original intention was.
