Client user - roles without panel access

Hello all.
I have set up protected pages for the first time and it seems to work fine - Clients log in to the site and see restricted access content but cannot log in to panel.
However, I noticed that if I log in to the site as client and then access the panel via URL I do get access with all writing permissions. Has anybody come across this?
My scripts are as described by Bastian here http://getkirby.com/docs/solutions/authentication#protecting-content
Did I miss something or perhaps this is a bug/known issue?

Cheers

Renato

Are you on the latest Kirby version? I remember that this used to be an issue but has been resolved since …

I am on Kirby 2. Upgrading to 2.1 as soon as I have a chance, specially if this issue is solved.
Checking release notes now!

Thanks @texnixe! Issue resolved with K2.1.
