Hi you both
I'm having a similar problem (using the latest Silverstripe). I've created a menu, made some of the pages visible only for a special group in the security panel, however something goes very wrong. This is what happens:
When you log in, not as an admin, but as a user in a special group, you get redirected to a page I've set using this tutorial from ssbits: http://ssbits.com/custom-login-form-with-group-based-redirection/ - this part works fine.
Now logged in as a user in this special group I can view the secured pages (this is possible since I'm getting redirected to one of them), but if I refresh the browser or just clicks on any other menu link, the user gets logged out and all the secured menu links gets hidden again.
Have you got any ideas what goes wrong? Sessions?
Thanks for your help
Joel
