Hudson ver. 1.285

1. When I enable "Matrix-based security".
2. Add group foo.
3. Grant all permissions to group foo.
4. Login as a new user in group foo to hudson.
5. Hudson displays following error

Access Denied

User is definitely in the group
Group definitely has all permissions

I didn't test if this also applies to non-LDAP groups.
