我正在尝试使用.NET 4应用程序(VisualStudio 2010)中AccountManagement命名空间/程序集中的类型来针对Active Directory对用户进行身份验证。这是我的代码:
private Boolean ValidateUser(String domainName, String userName, String password)
{
var ou = String.Format(CultureInfo.InvariantCulture,
"LDAP://{0}.mydomain.com/dc={0},dc=mydomain,dc=com",
domainName);
var domain = String.Format(CultureInfo.InvariantCulture,
"{0}.mydomain.com",
domainName);
using (var context = new PrincipalContext(ContextType.Domain,
domain,
ou))
{
if (context.ValidateCredentials(userName, password))
{
var userPrincipal = UserPrincipal.FindByIdentity(context,
IdentityType.SamAccountName,
userName);
return userPrincipal.IsMemberOf(context, IdentityType.Name, "GroupName");
}
return false;
}
}
代码运行良好,直到我调用FindByIdentity的语句。此调用会导致以下异常:
System.DirectoryServices.AccountManagement.PrincipalOperationException was caught

显然我的配置错误了。如果没有,也许我只是以错误的方式解决这个问题。
我的目标是简单地针对A / D对用户进行身份验证,然后确保他们是特定组(或组)的成员。我做错了什么?
答案 0 :(得分:0)
你能尝试像这样用餐:
var ou = String.Format(CultureInfo.InvariantCulture,
"dc={0},dc=mydomain,dc=com",
domainName);
根上下文不需要验证凭据。
