pages in iframes

Hi,
we are currently in the progress of updating a customers system where we
use jcifs for auto-login into our J2EE application from WinXP/IE SP2
workstations. In the old version of our application we used jcifs 1.0.1
for authentication. The new version of our application uses jcifs 1.2.9.
The J2EE application is also embedded into a Portal-Site via iframes. If
the application is accessed directly auto-login via jcifs works just
fine. If content from the application is included via iframes the
authentication fails with jcifs 1.2.9 (either auth-failure pages or a
login dialog pops up) but works just fine with the old version.
We can reproduce this problem if we are using a simple local html-file
with iframes which includes content from our application. Strange
though, we can only reproduce this at the customers site. We are unable
to reproduce it in-house. The customer found the following KB-article at
microsoft:
http://support.microsoft.com/kb/312176/EN-US/
with a suggested workaround to set a "MaxConnectionsPerServer" to 1. If
this param is set to 1, auth works fine with jcifs 1.2.9 but
unfortunately the customers needs this value to be 8 for another
application.
We also tried to set the ssnLimit to 1 without success. We are currently
testing a backport of the old jcifs but I would be happy if someone has
an idea what might cause this problem as backporting full support for
the old jcifs version would be a lot of work.
Thanx and kind regards,
Ingo
