Question

How to disable Java Login in Internet Explorer

Hey Y'all:

We are currently on Windchill 9.0 m060, and when we use Internet Explorer to access Windchill, whenever a java applet launches, we have to "login" or Authenticate to get the applet to run. I will attach a screenshot showing the login window.

Funny thing is when you do the same thing using FireFox, no authentication window appears. MUCH nicer. Because of that, I don't think it is the server requiring us to authenticate.

So: How to get rid of the authenticate login?

Thanks for the heads up. I was reading they put it on Java.com usually a week after release.

Hi,


i know that in 9.1 there is preference which can stop this double authentication, im not sure whether its applicable for 9.0

Set the Home#Utilities#PreferenceManager#PSE #Java Web Start preference to No in the Preference Manager.

Have any of you guys tried 1.6.23 yet?

I get a Windows error 'getCacheDescriptor' failed error preventing uploading of a new document. I was getting this with 1.6.22 as well.

In Reply to Thomas Busch:

Is there something additional that needs to be done? We've had 3 people so far try this and only 1 doesn't require authentication anymore.

It's true! However, I don't see it on java.com yet. You can get the JDK and JRE here: http://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html

I attempted to clear all the Java cache, including docandsetting\username\app data\sun... I still get the error. I reverted to 1.6.16.

You must check the Java Plug-In's own "remember this password"-like
checkbox to resolve known cases where double authentication would
otherwise occur.

Jesse,

It seems that the double authentication would not occur in the same Windows session. If I logged out and back in the Windows or restart the computer, the Applet authentication reappears in the first HTML client page with Applet. Is this still a limitation for new Windows session?

Once you select the Java Plug-In's checkbox (in its dialog on the
initial double authentication), then the double-authentication should no
longer occur.

Of course if anything removes %USERPROFILE%\Application
Data\Sun\Java\Deployment\security\auth.dat (or the Windows 7 equivalent
of this location), then, yes, you'll have to reauthenticate -- as this
is the file that retains the login information so as to prevent
reauthentication.

This has been a real issue for us so we're delighted it has finally been addressed...but we're not sure how it works. You still have to check the 'Remember password..' box but now it really does remember it. Our concern is that the login credentials (in our case windows login credentials) are being stored in that auth.dat. However, when the user changes their windows password it still seems to work ok. So, is that file actually storing the userid/password or is it somehow forcing the current credentials to be passed through?

I am not 100% certain how this file works internally.

What has come to light, however, is that the file only applies to a
single Windows login session. If you logout and log back in, you'll
have to re-authenticate with Java the first time you use an applet --
checking its own checkbox to remember the password.

There is now a Java request for enhancement (#7006861) to make this data
apply indefinitely rather than having it remain valid only for the
duration of a Windows login.
