Thanks to vhoang for pushing me just a little further. I had tried to expand the dialog box like I have others in VS for SSIS, but that did not work. What I did do is type in the password in the password box. Then I tabbed to the next box, which is not visible and entered the password again (with faith that I was in the confirm password box). And yep the OK button became available.
