Hello,

I have a problem with security-settings in
a .NET Application.

The application has a strong name and is full trusted ("Trust an
assembly" - Full Trust),
.NET Security is set "Local Intranet - medium trust".

The application ist installed on a network-drive.

Working-Directory and Configuration-Files are also on different
network-shares.

The application uses intensively XSLT and XML.

The following XSL-Transformation-process fails (without errors !):

Base-Document XML X is stored on network-folder A.

Transformation-Stylesheet XSL Z is stored on Networkfolder B

Additional datas comes from Lookupfiles XML A and XML B.
There is a special Stylesheet XSL A for deriving of values from XML A,
and special Stylesheet XSL B for deriving of values from XML B.
Both XSL A and XSL B will be imported from Stylesheet XSL Z.

The stylesheet XSL Z gets also 2 Parameter (Path and File of additional
XML A and XML B).
The Path and name of these XML-Files will be stored in variables for
further use in the imported Stylesheets XSL A and XSL B.
The imported stylesheets are in the same folder like Stylesheet Z.

XML A and XML B are stored in Network-Directory A.

If the transformation runs,  the deriving of values in XSL B fails.
No values will be found in XML B.

If I set the .NET-Security to "Local Intranet" - Full Trust,
the transformation works fine.

After spending some time for error-detecting and reading documentation,
I wrote
a little Test-Application only with the functionality, desribed above.

I installed this on a Network-Folder and put all Stylesheets and XML on
a subfolder
under the installation Folder.

It works fine !!!

But if I move the stylesheet XSL Z to a other Networkfolder (origin
Network-Folder B) - it fails.

If I set the "Local Intranet" to "Full trust" - it works fine !!

If you have any ideas or hints - many, many thanks for your feedback.

thanks
Thomas
