Filter chain halted as [:check_authentication] rendered_or_r

I have this page that you login in from. You get authenticated and then
bumped over to the appropriate page depending on what your role is:
Traveler, Travel Manager, Admin. All pieced work except for the role
asssociated with Travel Managers who get tossed out, apprarently when
they hit a before_filter to check authenication. However, it seams that
they are properly getting authenticated and moved along correctly in the
grand scheme of things before they are kicked. I get this error:

Filter chain halted as [:check_authentication] rendered_or_redirected.

I recently upgraded to rails 2.1.0 and only after I did that did I start
to see this error. Before this was a non-issue. Anyone have this
experience and how do I fix it? Thanks,

Find out why your check_authentication filter is rendering or
redirecting (as of rails 2.0 it is that which determines whether the
filter chain is halted or not. Previously it was the return value of
the filter that mattered.

As it turns out, many of my wows was the result of the fact that I
switched from using a webrick server to using a Mongrel server, and
Mongrel servers apperently handle session data differently and was
causing havoc - not to mention bucket loads of frustation - when I tried
to authenticate my users. Long story-short, I need to refactor some
code. In others news Internet Exploder still sucks.
