In CMO 1.1 you can try this:
- login as user in administrators role, who has access to CMO
- Go to Admin mode and click on CMO Settings in Tools section, open Security tab
Here you can define the list of administrative and user roles, that must have access to CMO. Roles must be separated by coma. Note that specified roles must have access to CMS Edit mode.
You can find details in "Administering EPiServer CMO" section of user guide: http://world.episerver.com/Documentation/Items/Manuals/EPiServer-CMO/User-Guide---EPiServer-CMO-10/
I have installed CMO 1.1 on a CMS5 R2 SP2 site. But after the installation was done I got a request of setting up a dedicated group for admin-access to CMO. Since I didn't know this beforehand i just let the default groups be in the installation (webadmins, administrators). Is there an easy way to add a newly created 'CMOAdmin'-group? I would think there was someplace in web.config this could be added, but I didn't see any obvious place to add it.
