--------------------------------

             Summary: RBAC:Ambari should be sensitve to the change of login 
user's permissions.
                 Key: AMBARI-21016
                 URL: https://issues.apache.org/jira/browse/AMBARI-21016
             Project: Ambari
          Issue Type: Bug
    Affects Versions: trunk
            Reporter: Yao Lei
             Fix For: trunk, 2.5.1


Steps to reproduce:
1.Login ambari with ambari administrator role and create a user named Test on 
host A.
2.Assign service administrator role(or any other one of five roles) to this 
user Test.
3.On host B, login ambari with user Test .Now it plays as a service 
administrato role.
4.On host A, unassign the role of user Test , or change the role to another 
one, or even delete this user.
5.On host B, we will find the user Test can continue to operate ambari with 
previous permissions as a service administrator which actually have already 
changed by step 4.

Except for on two different hosts, we also can reproduce this problem between 
two different browsers on local host.


One solution:
Periodly schedule a task to update current user's authorization. If any error 
happens in this process, we should log off current user.
