A form of ours, which is accessed as a User Task, contains a link to the Web Client that in Chrome and Firefox will take the user to the Web Client and pass credentials through so no additional login is required. in IE 11 (not sure of previous versions), the link takes the user to a the login page, then goes nowhere after pressing Sign In, i.e. the Sign In page simply refreshes. If, however, a user logs into the Web Client directly in another tab in IE, they can then login via the iframe in Forms without any issue.
Is behavior like this known, and is there a fix on the back-end?
We're running Rio 10.2, Forms is 10.2.1.157, Web Client is 10.2.1.277
