Symptoms

In our SharePoint 2013 dev environment, we have activated an old SP2010 feature "Sign in as different user". From our K2 site project, we load a Smartform and at the view level, there exists a rule that "When the View executed Initialized ... then show a message to the user" The message alerts the user of their Email, FQN, and Display_Name. These values are derived from the Context_Browser's System_Values | Current_User.

When I used "Sign in as different user" to switch logon account, the K2 Smartform alert still displays the old logon Email, FQN, and Display_Name. Shouldn't the Current_User context follows the SharePoint's new logon account?
 

Diagnoses

I believe this is expected. When using the sign in as different user within SharePoint the browser is still running under the identity of the user that started the session and the tokens for that user will be passed. To use a different user you will need close the browser and perform a run as for the desired user.

 

Resolution

The customer will use separate browser with run as option.
