Hi All,

 

Sorry to bounce this up the list again, but I’d ignored it before as it wasn’t causing a real problem for us, but have just come across it again so thought I’d update the thread in case anyone else comes across this.

 

Anyway, I’ve pretty much pinned down reproducing the problem, although not 100% exactly what the issue is.

 

Just to remind, I get a Shib 404 error after putting in my credentials when using a combination of Windows 7 / IE 8.

 

After some further investigation the problem seems related to having Sophos installed... it installs a plug-in into IE that checks webpages, and it seems to be that that’s messing things up. It’s fine in Vista, just seems specific to Windows 7. If you disable the plug-in, everything seems to work as expected.

 

I’ll report the problem to Sophos and see what they say.

 

Didn’t find anything on this in Google, so thought I’d post here just in case anyone else has a similar set up and it causes them any issues.

 

Cheers,

 

Steve

Subject: Shib 2 and Windows 7 / IE8 problems

 

Hi All,

 

I’ve noticed a strange one here and wondered if anyone else has come across this and can help me fix?!

 

We run IDP (Shib2) on Windows 2008 Core, with Apache and Tomcat. All’s worked well for quite some time, don’t really touch it.

 

Anyway, I was logging into a site today and after entering my credentials, instead of sending me back to the site I was going to, I just get a 404 page not found message.

 

I’ve tried various IE’s from 6 to 8 on Windows XP, and everything works fine.

I’ve tried IE 7 and IE8 from Vista, and again everything works fine.

Using IE8 on Windows 7, and I get the 404 message.

 

Looking in the logs within Shib, I can see the following error:

 

ERROR [edu.internet2.middleware.shibboleth.idp.authn.AuthenticationEngine:211] - No login context available, unable to return to authentication engine

 

However, just to underline, that only ever happens on Windows 7 clients with IE8... earlier versions of windows seem fine. Also Chrome on Windows 7 works fine.

 

Any ideas?!

 

Many thanks,

 

Steve
