Custom Assembly Security Error

I have created a custom assembly that contains a function that uses
System.DirectoryServices to determine the user groups a user belongs to. It
works fine in development (preview) but returns the following error on the
report server:

"Request for the permission of type
System.Security.Permissions.SecurityPermission, mscorlib, Version=1.0.5000.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089 failed."

- I have another function in the same assembly that uses
System.Data.SQLClient to access a database and return values - this works
fine.

- I have included a codegroup for the assembly in rssrvpolicy.config with
the FullTrust permissionset.

- I have tried combinations of the following in the assemblyInfo.cs file:
[assembly: DirectoryServicesPermission(SecurityAction.RequestMinimum,
PermissionAccess=DirectoryServicesPermissionAccess.Browse)]
[assembly:
System.Security.Permissions.SecurityPermission(SecurityAction.RequestMinimum,
Unrestricted = true)]
[assembly: AllowPartiallyTrustedCallers]

- I have tried the following at the top of the function:
System.DirectoryServices.DirectoryServicesPermission pDir = new
DirectoryServicesPermission(System.Security.Permissions.PermissionState.Unrestricted);
System.DirectoryServices.DirectoryServicesPermissionEntry pDirEnt = new
DirectoryServicesPermissionEntry(System.DirectoryServices.DirectoryServicesPermissionAccess.Browse,"");
pDir.PermissionEntries.Add(pDirEnt);
pDir.Assert();

Please help!
I have been trying to solve this for ages and just cannot find a solution.

Hey, are you using 1.1 of the framework on the web server? If you do have it
installed, it doesn't look like it is installed for that virtual web.

I would like to suggest to first refresh the framwork installation on the
web server.

in %systemroot%\microsoft.net\framework\v1.1.4322\

installutil /i

The only reason I say that is because this number bugs me: "...mscorlib,
Version=1.0.5000.0, "

I just verified the version on my server with the 1.1 version of the
framework, and my version says:

1.1.4322.2251 for MSCORLIB.DLL.

Thanks for your suggestion.
I have no idea what the 1.0.5000.0 is for.
I have reinstalled .net framework 1.1 and my version of mscorlib.dll
is 1.1.4322.573.
Still no change.

I have also tried the following in my function:
System.Security.Permissions.SecurityPermission pSec = new
SecurityPermission(System.Security.Permissions.PermissionState.Unrestricted);
pSec.Assert();

System.DirectoryServices.DirectoryServicesPermission pDir = new
DirectoryServicesPermission(System.Security.Permissions.PermissionState.Unrestricted);

pDir.Assert();
which results in this error:
"Stack walk modifier must be reverted before another modification of the
same type can be performed."
