I installed GP 2013 R2 last week and am slowly encountering a few changes and new features.
One change that jumped out at me was the redesigned User Setup window.
GP 2013 SP2:
GP 2013 R2:
Obviously the R2 window has the rather "prominent" ribbon at the top, but aside from that global change in R2, the User Setup window has a few interesting additions.
User Type: Full vs. Limited. A Limited user is apparently "restricted to inquiries and reports" only. And if the user is a member of the POWERUSER role, you cannot change the user from Full to Limited. As such, you cannot change the sa or DYNSA logins from Full to Limited.
Web client user only: This allows you to specify that the user is for the web client only, and will use their Windows account to login rather than a SQL login.
There are now two tabs on the window--one for SQL Server Account info, and the other to specify a Windows Account for web client users.
Last, there is a Home Page Role field. The help file explains:
Assign the user to a user role. The user role determines the content that is displayed on a user’s home page by default.On my install, that field is disabled, so I don't know if I am missing some configuration options, or if that is a future feature.
