CLR procédure stockée SQL pour interroger Active Directory

Question

-je obtenir des informations auprès des utilisateurs dans la base de données qui sont stockées sur Active Directory, j'ai une fonction simple à faire:

using (DirectoryEntry de = new DirectoryEntry("LDAP://ANYGIVENDOMAIN")) 
{ 
    using (DirectorySearcher adSearch = new DirectorySearcher(de)) 
    { 
     adSearch.Filter = "(sAMAccountName=jdoe)";     
     SearchResult adSearchResult = adSearch.FindOne(); 

     StringBuilder sb = new StringBuilder(); 
     sb.AppendLine(adSearchResult.Properties["displayname"][0].ToString()); 
     sb.AppendLine(adSearchResult.Properties["givenName"][0].ToString()); 
     sb.AppendLine(adSearchResult.Properties["objectSid"][0].ToString()); 
     sb.AppendLine(adSearchResult.Properties["description"][0].ToString()); 
     sb.AppendLine(adSearchResult.Properties["objectGUID"][0].ToString()); 
    } 
} 

Exécution d'un WinForm fait ce que je veux, mais dans le type de projet SQL Server, je ne peux pas ajouter l'espace de noms System.DirectoryServices aux références.

Quelqu'un sait pourquoi?

Cordialement

Voir: Supported .NET Framework Libraries

Unsupported libraries can still be called from your managed stored procedures, triggers, user-defined functions, user-defined types, and user-defined aggregates. The unsupported library must first be registered in the SQL Server database, using the CREATE ASSEMBLY statement, before it can be used in your code. Any unsupported library that is registered and run on the server should be reviewed and tested for security and reliability.

For example, the System.DirectoryServices namespace is not supported. You must register the System.DirectoryServices.dll assembly with UNSAFE permissions before you can call it from your code. The UNSAFE permission is necessary because classes in the System.DirectoryServices namespace do not meet the requirements for SAFE or EXTERNAL_ACCESS.
