I’m using a authentication profile that tries Active Directory, then fails over to internal authentication if necessary. If I go to the Designtime Security Tool, it pulls in about 40 roles from AD (most of which aren’t relevant, but that’s expected). The list, however, is longer than will fit in the window, but there’s no scroll bar, making some of the roles unreachable. I can even use the keyboard to move the cursor down the list, off the visible area of the window.
Also in this tool, I can shuttle roles out of the Selected Roles section to the left, and they disappear from that pane, but they never appear in the Available Roles pane, which is always empty. That makes it a one-way trip, and there’s no way to get them back, other than logging in again.
