Problems with Active Directory

sql server reporting services:
I'm having a problem using SQL Server Reporting Services in a deployment of a
project which makes use of an assembly which reads from an Active Directory
attribute.

I'm trying to read an Active Directory attribute using a class created in
VB.NET, the following is the code used:
Public Function GetUserInfo(ByVal inSAM As String, ByVal inType As
String) As String
Try
Dim sPath As String = "LDAP://Dominio" '' Dominio donde se buscara
Dim SamAccount As String = Right(inSAM, Len(inSAM) - InStr(inSAM,
"\")) ''' Usuario que se buscara
Dim myDirectory As New DirectoryEntry(sPath, "dominio\user",
"password") 'pass the user account and password for your Enterprise admin.
Dim mySearcher As New DirectorySearcher(myDirectory)
Dim mySearchResultColl As SearchResultCollection
Dim mySearchResult As SearchResult
Dim myResultPropColl As ResultPropertyCollection
Dim myResultPropValueColl As ResultPropertyValueCollection
'Build LDAP query
mySearcher.Filter = ("(&(objectClass=user)(samaccountname=" &
SamAccount & "))")
mySearchResultColl = mySearcher.FindAll()
'I expect only one user from search result
Select Case mySearchResultColl.Count
Case 0
Return "Null"
Exit Function
Case Is > 1
Return "Null"
Exit Function
End Select
'Get the search result from the collection
mySearchResult = mySearchResultColl.Item(0)
'Get the Properites, they contain the usefull info
myResultPropColl = mySearchResult.Properties
'displayname, mail
'Retrieve from the properties collection the display name and
email of the user
myResultPropValueColl = myResultPropColl.Item(inType)
Return CStr(myResultPropValueColl.Item(0))
Catch ex As System.Exception
'do some error return here.
End Try
End Function
The class seems work correct in Design View, but when I try to deply, a host
assembly security error is displayed. I understand one has to modify the
configuration files of Reporting Services en enable correct security,
(rssrvpolicy.config and rspreviewpolicy.config), I've done this but am seeing
the
same error. Also, I've copied the dll file of the assembly to the /bin
directory of
Reporting Serivices and to the Report Designer directory as indicated, but
still no luck with the error.
Permissions seem to be set correcty in the Virtual Directory of Reporting
Services.
For the Deployment, I've set up the project properties as follows:
OverwriteDateSources=True
TargetFolder=pruebadll
TargetServerURL=http://lopezcarlos/reportserver
In the configuration files I've setup in the following manner, apparantely
it's not
working:
<CodeGroup
class="UnionCodeGroup"
version="1"
Unrestricted="true"
PermissionSetName="FullTrust"
Name="MyCustomAssemblyCodeGroup"
Description="Codigo especial para leer el active directory">
<IMembershipCondition
class="UrlMembershipCondition"
version="1"
Url="E:\Program Files\Microsoft SQL Server\MSSQL\Reporting
Services\ReportServer\bin\MyCustomAssembly.dll" />
</CodeGroup>
In the Property References section of the report, a reference to itself is
made,
and in the preview of Visual Studio .NET 2003 the reports is visualized
correctly.
the problem occurs in the deployment process.
When deployed, the report displays the following error:
Error on loading the host assembly. Details: Security Error
(rsProcessingError)

The following link has the information I've used to do the design of the
report,:

Thanks for the help.

Carlos,

Try this:

1. In the rssrvpolicy.config, create a new PermissionSet class containing
the DirectoryServicesPermission and associate your assembly with similar to
the thread
http://groups.google.com/groups?q=assert+group:*.reportingsvcs+author:teo&hl=en&lr=&selm=ez9iQJqSEHA.1472%40TK2MSFTNGP09.phx.gbl&rnum=1

or

http://groups.google.com/groups?hl=en&lr=&threadm=OQe%24dsjhEHA.140%40TK2MSFTNGP12.phx.gbl&rnum=3&prev=/groups%3Fq%3Dpermissionset%2Bassert%2Bgroup:*.reportingsvcs%26hl%3Den%26lr%3D%26selm%3DOQe%2524dsjhEHA.140%2540TK2MSFTNGP12.phx.gbl%26rnum%3D3

In your case, you won't be using FileIOPermission but
DirectoryServicesPermission

2. In your assembly before the FindAll call assert the
DirectoryServicesPermission

Dim ps As New PermissionSet(PermissionState.None)
Dim dsp As DirectoryServicesPermission

dsp = New
DirectoryServicesPermission(DirectoryServicesPermissionAccess.Browse)
ps.AddPermission(dsp)

' Stop security checks at this point in the stack walk for the specified
permissions
ps.Assert()

3. Reading the documentation on DirectorySearcher, you may need to add the
AllowPartiallyTrustedCallers attribute to your custom assembly.
