c# - 在 Active Directory : A device attached to the system is not functioning 中创建用户

Question

考虑此代码尝试创建一个 Active Directory 帐户。它在这里使用一组特定的数据生成异常。目前尚不清楚是什么导致了异常。

 var user = new UserPrincipal(someValidUserContext,
                              ".x-xyz-t-FooFooBarTest", "somePwd", true);

 user.UserPrincipalName = ".x-xyz-t-FooFooBarTest@foobarbatbaz.net";
 user.SamAccountName = ".x-xyz-t-FooFooBarTest";         
 user.DisplayName = "Some String 16 chars long";
 user.Name =  "Some String 16 chars long";
 user.Description = "Foo BarBaz 12 more characters";
 user.AccountExpirationDate = someDateInFuture;
 user.UserCannotChangePassword = true;
 user.Save();

 // exception thrown on Save(): 
 // A device attached to the system is not functioning

PrincipalOperationException was unhandled by user code: A device attached to the system is not functioning

导致此异常的原因是什么，您该如何解决？
