Moodle 1.7 (to be released shortly) lets you do this.

No, that's incorrect. That table is just for the GUI, in that it says "Admins can set overrides on Teachers".

Capabilities in different roles do not have priority in calculations. An ALLOW in one role will exactly cancel a PREVENT from another role (in any given context), and the system will look to HIGHER contexts to resolve it (and if it can't find anything then you effectively have no permission there).

The problem is really the missing help files, which is my bug MDL-6923

Coming real soon now!

It would be great for those using Hotpot to help Gordon out here.

Firstly by commenting/supporting/altering/prioritising this list.

Secondly by offering Gordon your financial support. So far he's been working on Hotpot totally in his own limited time and it would really help him (and you, if you use hotpot) if you can help fund his activities.

I've been planning a big Moodle funding drive for some time, but have been struggling with good processes to distribute raised funds to various programmers. We need some sort of system that tracks payees etc... I don't know of one (and haven't had time to build one).

Until then, if you want to donate directly towards Gordon's work I'm happy to collect all Paypal donations sent to payment@moodle.com with "Hotpot" in the comments and bank transfer them to Gordon, if that helps.

There's no known bug like this (except in current 1.7 beta where forum posting can be quite cpu-intensive, it's being worked on).

What version of Moodle are you running?

Firstly CONGRATS on the launch!!

Secondly, I'm looking at the code and I do indeed see the problem with opentogoogle (capabilities are not loaded for google!) ... Here's the fix! (I filed a bug in the tracker for it too: MDL-7229)
