Although adding the <see cref="T:System.DirectoryServices.DirectoryServicesPermission" /> permission to a partial-trust policy file will enable use of the <see cref="T:System.Web.Security.ActiveDirectoryMembershipProvider" /> class, doing so makes the <see cref="N:System.DirectoryServices" /> namespace classes available to any code running in your ASP.NET pages. This option is not recommended for any Web servers that need to run in a secure, locked-down mode.</para><para>As an alternative, you can create a "sandbox" assembly that calls the <see cref="T:System.Web.Security.ActiveDirectoryMembershipProvider" /> class. This assembly can contain either a wrapper class that forwards method calls to the <see cref="T:System.Web.Security.ActiveDirectoryMembershipProvider" /> class or a class that derives from the <see cref="T:System.Web.Security.ActiveDirectoryMembershipProvider" /> class. In either case, the wrapper class must assert unrestricted <see cref="T:System.DirectoryServices.DirectoryServicesPermission" /> permission. Deploy the sandbox assembly in the GAC and mark the assembly with the <see cref="T:System.Security.AllowPartiallyTrustedCallersAttribute" /> (APTCA) attribute. This will enable your partially trusted ASP.NET code to call your wrapper class, and since the wrapper class internally asserts the unrestricted <see cref="T:System.DirectoryServices.DirectoryServicesPermission" /> permission, your wrapper class will be able to successfully call the provider</para></block><para>You must create a <format type="text/html"><a href="b6ffbb2e-a4d1-410e-8f7e-9755e92c65de">connectionString</a></format> entry in the Web.config file that identifies the Active Directory server, Active Directory domain, or ADAM application partition to use.
