Hi,

I'm developing a report that calls a web service using a custom assembly.
I've got the code working in VS.NET, but when I deploy to my local Report
Server, I get this:

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

I have added the following to RSReportServer.config:

 <CustomAssemblies>
    <Assembly Name="cmcs.wsclient.dll, Version=1.0.xxx.xxxx,
Culture=neutral, PublicKeyToken=xxx">
     <PermissionSet class="System.Security.PermissionSet">
        <IPermission
           class="System.Security.Permissions.SecurityPermission"
           version="1"
            Flags="Execution, Assertion"
        />
        <IPermission class="System.Security.Permissions.WebPermission"
           version="1"
           Unrestricted="true"
        />
        <IPermission
class="System.Security.Permissions.EnvironmentPermission"
  version="1"
           Unrestricted="true"
  />
     </PermissionSet>
  </Assembly>
    <Assembly Name="cmcs.msrs.webserviceclient, Version=1.0.xxx.xxxx,
Culture=neutral, PublicKeyToken=xxx">
     <PermissionSet class="System.Security.PermissionSet">
        <IPermission
           class="System.Security.Permissions.SecurityPermission"
           version="1"
            Flags="Execution, Assertion"
        />
        <IPermission class="System.Security.Permissions.WebPermission"
           version="1"
           Unrestricted="true"
        />
        <IPermission
class="System.Security.Permissions.EnvironmentPermission"
  version="1"
           Unrestricted="true"
  />
     </PermissionSet>
  </Assembly>
  <Default>
     <PermissionSet class="System.Security.PermissionSet">
        <IPermission
           class="System.Security.Permissions.SecurityPermission"
           version="1"
           Flags="Execute"
        />
     </PermissionSet>
  </Default>
</CustomAssemblies>

In rssrvpolicy.config, I have changed the PermissionSet for
Report_Expressions_Default_Permissions to FullTrust and added the following:

                 <CodeGroup class="UnionCodeGroup"
                            version="1"
                            PermissionSetName="FullTrust"
                            Attributes="LevelFinal"
                            Name="ReportServer-cmcs.msrs.webserviceclient"
                            Description="Codegroup generated by the .NET
Configuration tool">
                    <IMembershipCondition class="UrlMembershipCondition"
                                          version="1"
                                          Url="file://C:/Program
Files/Microsoft SQL Server/MSSQL/Reporting
Services/ReportServer/bin/cmcs.msrs.webserviceclient.dll"/>
                 </CodeGroup>

It works to call a HelloWorld method returning a string from the custom
assembly, so there is no total failure, but calling the method to invoke the
web service fails.

Please help, I feel that I'm totally stuck!
