In SC user management console:
Currently we have option to search user by 'Firstname', 'Lastname', 'login' & 'title'.
I know we can get all the above including 'email ID' by downloading the entire table.
From my experience I felt that, we should be able to search user by email ID too.
Because when an admin wanted to remove a user account who quit job,
admin wouldn't be having more info than email ID, atleast may be from bounced email.
Thanks
