Old topic but... staff email addresses here now have a . in - it didn't seem to break the IdP or our SP on our moodle instance which uses shibboleth SSO for some users (we were going to switch everyone on LDAP to Shibb, but have hit a problem with SSO to/from another of our websites when shibboleth is used - so that switch is on hold).

Not that I know of, but it would probably not be a good idea for the usual reasons that's generally not a good idea. It will break something somewhere or end up requiring escaping.
