Can't connect as different user while accessing network share with in domain network in Mac Can't connect as different user while accessing network share with in domain network in Mac.
Through Go > Connect to server > connect as
I am having the same issue. I am logged in with userA. I can see all of the shares. I want to access a specific share that userA does not have access to that userB does. I disconnect from server, but 'connect as' does not do anything when I click it

I found a workaround: 


Go to Finder
Click Go, then Connect to Server
Create a path of smb://userB@myserver
