I'm having a problem with redirects.

We have a WP Multi-Site installation and when we direct someone to a members-only page, the default redirect doesn't work (eg: /login/?redirect_to=http://myawesomesite.com/the-link-i-want-them-to-go-to/). It, instead, takes them to a user dashboard (/login/, after being logged in). This is despite having the WPMU-Dev Login Redirect plugin installed. The redirect plugin DOES work if they go to the /login/ page directly and log in there. Thoughts?
