Playing with the panel delegation I maybe found a bug in /usr/share/nethesis/NethServer/Authorization/base.json
{
"Id": 1328028218,
"Effect": "ALLOW",
"Subject": ".groups HAS managers",
"Action": ["QUERY OR MUTATE OR INSTANTIATE", "WRITE"],
"Resource": [".category IS Management", "Nethgui\\System\\EsmithDatabase:accounts"],
"Description":
"Managers can access modules in Management category and write accounts database"
}
like you can see the Managers group can change settings in the Management section, but only the accounts database can be modified by the members of this group.
It gives an issue for example for the virtualhost panel because the database is vhosts (no permission granted on it)
