Hi Jens,

Using the web interface is the only option currently. I filed a bug for 
adding permissions management to cli.

You can edit the file safely with the cluster (corosync, pacemaker and 
even pcsd) running. However this file is synchronized across the cluster 
nodes automatically by pcsd. You can edit it manually at any time but 
you need to increment the "data_version" field enough to be the highest 
across the cluster before saving the file. Otherwise your changes will 
be lost in the synchronization process. Also be careful not to make any 
error in the file as it would lead to the file being restored from other 
cluster nodes and your changes being lost.

Hope that helps,
