I have a question about the visibility of Task forms. We have a custom emai

Thanks for all the feedback.

@Annelise, I updated the process instance security and found that if I updated the Viewer role, the task could be secured. Thank you for pointing this out.
Just to clarify: users with rights to "view task reports" can view the task form (as read only)?

@Cesar, my issue is that basic users can see the task form. These users are not included in the Editor, Manager or Administrator role process security settings.

This is what I observed in my case:

Let's say there are six basic users,
basic1,
basic2 (belongs to Group A),
basic3 (belongs to Group B),
basic4 (belongs to Group C),
basic5 (belongs to Group D),
basic6 (belongs to Group E).
Assume initially task is assigned to ONLY basic1, so normally he can accept and complete the task.

Scenarios:
------------------------------------------------------------------------------
Process Which what happens if the
Model group forwarded link opened by
Security given respective group basic user
--------- -------- ----------------------------
Editor Group A Can accept the task and
                                                                      complete it
Manager                     Group B Can accept the task and
                                                                      complete it
Viewer                     Group C Can see the task/form in
                                                                      read-only mode
Initiator                     Group D "The requested task is not available
                                                                      ...." error message.
Deny                     Group E "The requested task is not available
                                                                      ...." error message

------------------------------------------------------------------------------
                                                                                                              
Note: basic1 is task assignee, Group A,B,C,D,E given process model security as mentioned above.
If the task is opened by any other basic user(who is not in process model security groups/task assignee group)
"The requested task is not available..." error message will be shown.

@Mike, yes that's correct.

An update to the documentation which hopefully makes all of this much clearer is now available. See forum.appian.com/.../Configuring_Process_Security.html. Thank you, and sorry for the confusion.

Thanks Tim, that's much clearer.
