I would like to restrict a specific group not to access crxde lite in author mode .
Is there any way to do that ?
suggestions are really appreciated,thx.
You can write a sling filter with a pattern property. Check runmode. Get UserId. Then get Authorizable from UserManager. Then you can call memberOf() method on Authorizable.
This is first what came to my mind. Maybe there are better ways to reach you goal.
