I need to run a console application that loops through all a server's repositories and then lock each repository's volumes. I have one Windows AD account as admin to all the repositories.

I'v managed to Impersonate and set the WindowsIdentity to this AD account, and server.GetRepositories() is calling successfully. However, when i try session.Login(repository), it's giving me Access Denied.

RepositoryRegistration repository = new RepositoryRegistration(serverName, repoName);
session.LogIn(repository);

I even tried setting the Thread's CurrentPrincipal Identity based on that of the WindowsIdentity, and it's still not working. What am i missing?

// Retrieve a GenericPrincipal that is based on the current user's WindowsIdentity.
GenericPrincipal genericPrincipal = GetGenericPrincipal();

// Retrieve the generic identity of the GenericPrincipal object.
GenericIdentity principalIdentity = (GenericIdentity)genericPrincipal.Identity;

Thread.CurrentPrincipal = genericPrincipal;



// Create a generic principal based on values from the current WindowsIdentity.
        private static GenericPrincipal GetGenericPrincipal()
        {
            // Use values from the current WindowsIdentity to construct
            // a set of GenericPrincipal roles.
            WindowsIdentity windowsIdentity = WindowsIdentity.GetCurrent();
            string[] roles = new string[10];
            if (windowsIdentity.IsAuthenticated)
            {
                // Add custom NetworkUser role.
                roles[0] = "NetworkUser";
            }

            if (windowsIdentity.IsGuest)
            {
                // Add custom GuestUser role.
                roles[1] = "GuestUser";
            }

            if (windowsIdentity.IsSystem)
            {
                // Add custom SystemUser role.
                roles[2] = "SystemUser";
            }

            // Construct a GenericIdentity object based on the current Windows
            // identity name and authentication type.
            string authenticationType = windowsIdentity.AuthenticationType;
            string userName = windowsIdentity.Name;
            GenericIdentity genericIdentity =
                new GenericIdentity(userName, authenticationType);

            // Construct a GenericPrincipal object based on the generic identity
            // and custom roles for the user.
            GenericPrincipal genericPrincipal =
                new GenericPrincipal(genericIdentity, roles);

            return genericPrincipal;
        }
