We've had a couple shibboleth authentication problems since we updated to 
1.6.2. At the same time the service was moved to another computer. That means I 
can not be sure whether this is a problem of DSpace or only our shibboleth 
authentication installation.

Problem is, that sometimes I cannot log into DSpace with an account at some 
specific computer/browser. For example at this moment my account work right 
with Mozilla Firefox, but at the same computer login with Internet Explorer has 
an answer: Authentication Failed.

Part of dspace.log of that Internet Explorer trials:
2011-01-31 08:44:03,035 INFO  org.dspace.authenticate.ShibAuthentication @ 
Shibboleth login started...
2011-01-31 08:44:03,035 INFO  org.dspace.authenticate.ShibAuthentication @ 
RemoteUser identified as: null
2011-01-31 08:44:03,035 ERROR org.dspace.authenticate.ShibAuthentication @ No 
email is given, you're denied access by Shib, please release email address
2011-01-31 08:44:03,035 INFO  org.dspace.authenticate.ShibAuthentication @

2011-01-31 08:44:03,035 INFO  org.dspace.authenticate.ShibAuthentication @

201
So the Shibboleth don't give the email address to DSpace.

At earlier case couple of weeks ago I couldn't log in with this computer with 
either browser, but when I tried with computer/browser combination which is not 
in same Windows domain and which I haven't used earlier to log into DSpace it 
worked well (with the same DSpace account).
Restarting the shibboleth service helps but the problem has appeared again 
after a few weeks.

While this could be a problem of our organization's shibboleth service, I'm 
asking if somebody has seen something like this and could this be a problem of 
DSpace? To me it seems some kind on session problem.
