For users to have access to Elipse E3 in Read-Only mode, at least one of these conditions must be true:

•The license in use must be a Viewer Only type

•A logged-on user with no permission to access a Writing access to the server item

It is worth noticing that in case there is no user logged on an Elipse E3 Viewer, that is, an anonymous user, access restrictions apply as long as one or more users have this restriction.

Thus, every time a user changes, Elipse E3 Viewer's access mode can be changed, and consequently the IsReadOnly property, according to the result of a combination between what is permitted by the license in use and the permission of the logged-on user.

Changing access mode can also happen in case there is an Elipse E3 Viewer reconnection, since it can trigger either a license change, from Viewer Control to Viewer Only or vice versa, or a change in permissions of the logged-on user.

In case there is any user with a blocked writing access to a server when Elipse E3 Viewer opens, they enter this application automatically in Read-Only mode, regardless of the license in use, since an anonymous user always assume the maximum configured restriction.
