There is always a risk in doing that.  Much of it depends on how well you did the application.  How are you expecting to use it?

It depends on application's reliability and security.

Only if the app is insecure.  If you are only forwarding that port to that machine, then the only security risk is the app running on that port.

All depends on how secure your webserver is and not on port numbers.

This said, port 8081 is as risky (or not)as port 80 is.

You should have a login at least.  And don't link the application on a 'public' page.

absolutely the application is connected to our AD on the server so authentication is performed through there

End result, if you trust the webpage to public access, then which port you are using is unimportant.

As long as you don't list the port on any public resources, I would change the port to something other than this default.  8081 is kind of a common webserver port, so a hacker may try this port if he knows the domain along with port 80 and other common ports.  You could use a non-common port to run your website on and then the only way someone would know how to get in would be by doing a port scan and find it open.  But, like people said above, the security risk would be based on your application code.  If it has holes, then someone could hack it.
