Re: Cosign @ uMich and logging out

Hi Kevin,

thanks for you that. Just to clarify, you have a logout button in all of
the applications (at least the main ones) which use this CGI and
redirect them to the UniSign logout. So each time they logout of an
application it will ask them if they which to logout of 'everything'

Also, like Mark said, if they hit cancel wont it send them back to the
application and 'log' them back in again?

I am asking these questions to get an idea on how you guys handle the
logout problems. Also, how did you students react to the SSO and logout
changes? Dod you do a large communication of this when you went live?

Thanks heaps, and sorry for the pestering (Bosses and their insistance
on this :) )
