AccessControlService and Permission cache [message #840650]

I have following problem:

In my Application, the AccessControlService loads the Permissions for each user from a Database.

The application also provides a way to edit the corresponding database records (kind of administration Outline).

From what I have seen, the server calls the AccessControlService when a new user logs in. I assume the Permissions are cached after this.

After a modification of the database in the admin view, I somehow need to invalidate the cache.

I could imagine that the user needs to restart the client in order to have his modification on the Permission (force to refresh the Permission Cache after Log-in). But even this do not work yet.

What are the best practices? and how do I take control of the permission cache?

Just found:
* clearCache()
* clearCacheOfUserIds(String... userIds)
in the service extending IAccessControlService.

I still do not understand:
* Why isn't there any clear Cache for the user just after new log-in (restart of the client) or when the user quit the client application?
* When is the cache invalidated if none of the clear functions are called?

Is there any best practices?

By default the TTL Cache in the AccessControlStore has a time to live from 3600000 milliseconds = 1 hour

org.eclipse.scout.rt.server.services.common.security.internal.AccessControlStore:

    m_store = new TTLCache<String, Permissions>(3600000L);
