You would need to edit the source of Guacamole and remove the various calls to "clipboardService", which is the service that attempts to read/write the local clipboard:
https://github.com/apache/incubator-guacamole-client/blob/0.9.10-incubating/guacamole/src/main/webapp/app/index/controllers/indexController.js#L128-L148 https://github.com/apache/incubator-guacamole-client/blob/0.9.10-incubating/guacamole/src/main/webapp/app/client/controllers/clientController.js#L409-L411 https://github.com/apache/incubator-guacamole-client/blob/0.9.10-incubating/guacamole/src/main/webapp/app/client/controllers/clientController.js#L515-L519 If you do that and rebuild the .war, local clipboard will no longer be integrated, and you will not be prompted. It'd be awfully nice if the browser would just remember the permission grant per-domain... - Mike On Sat, Jan 14, 2017 at 10:43 AM, Peter Burdine <pburd...@gmail.com> wrote: > Thank you for the new release! > > Our users are getting prompted to enable clipboard integration each time > they login.
