我们正在使用foll。用于检索AD用户及其详细信息的代码: -
我们得到错误:SearchResultCollection resultCol = search.FindAll();
异常是:DirectoryServiceCOMException:操作错误 发生了。在System.DirectoryServices.DirectoryEntry.Bind(布尔值 throwIfFail)在System.DirectoryServices.DirectoryEntry.Bind()中 在System.DirectoryServices.DirectoryEntry.get_AdsObject()at System.DirectoryServices.DirectorySearcher.FindAll(布尔 findMoreThanOne)at SharePointProject20.VisualWebPart1.VisualWebPart1.GetADUsers()
public List<Users> GetADUsers()
{
try
{
List<Users> lstADUsers = new List<Users>();
string DomainPath = "LDAP://DC=SYSDOM,DC=local";
DirectoryEntry searchRoot = new DirectoryEntry(DomainPath);
DirectorySearcher search = new DirectorySearcher(searchRoot);
search.Filter = "(&(objectClass=user)(objectCategory=person))";
search.PropertiesToLoad.Add("samaccountname");
search.PropertiesToLoad.Add("mail");
search.PropertiesToLoad.Add("usergroup");
search.PropertiesToLoad.Add("displayname");//first name
SearchResult result;
SearchResultCollection resultCol = search.FindAll();
if (resultCol != null)
{
for (int counter = 0; counter < resultCol.Count; counter++)
{
string UserNameEmailString = string.Empty;
result = resultCol[counter];
if (result.Properties.Contains("samaccountname") &&
result.Properties.Contains("mail") &&
result.Properties.Contains("displayname"))
{
Users objSurveyUsers = new Users();
objSurveyUsers.Email = (String)result.Properties["mail"][0] +
"^" + (String)result.Properties["displayname"][0];
objSurveyUsers.UserName = (String)result.Properties["samaccountname"][0];
objSurveyUsers.DisplayName = (String)result.Properties["displayname"][0];
lstADUsers.Add(objSurveyUsers);
}
}
}
return lstADUsers;
}
catch (Exception ex)
{
return null;
}
}
public class Users
{
public string Email { get; set; }
public string UserName { get; set; }
public string DisplayName { get; set; }
public bool isMapped { get; set; }
}
可能是什么问题?
我们的域名是SYSDOM.local
它是否与权限相关(如何与网络管理员验证?),还是我需要明确传递用户名/密码?

如果您使用的是.NET 3.5及更高版本,则应查看System.DirectoryServices.AccountManagement
(S.DS.AM)命名空间。您可以使用PrincipalSearcher
和“按示例查询”主体进行搜索:
// create your domain context
using (PrincipalContext ctx = new PrincipalContext(ContextType.Domain))
{
// define a "query-by-example" principal - here, we search for a UserPrincipal
UserPrincipal qbeUser = new UserPrincipal(ctx);
// create your principal searcher passing in the QBE principal
PrincipalSearcher srch = new PrincipalSearcher(qbeUser);
// find all matches
foreach(var found in srch.FindAll())
{
// do whatever here - "found" is of type "Principal" - it could be user, group, computer.....
}
}
如果您还没有 - 绝对阅读MSDN文章Managing Directory Security Principals in the .NET Framework 3.5,该文章很好地展示了如何充分利用System.DirectoryServices.AccountManagement
中的新功能。或者查看MSDN documentation on the System.DirectoryServices.AccountManagement命名空间。
当然,根据您的需要,您可能希望在您创建的“按示例查询”用户主体上指定其他属性:
DisplayName
(通常:名字+空格+姓氏)SAM Account Name
- 您的Windows / AD帐户名称User Principal Name
- 您的“username@yourcompany.com”样式名称您可以在UserPrincipal
上指定任何属性,并将其用作PrincipalSearcher
的“按示例查询”。
构建示例中显示的PrincipalContext
将使用当前用户凭据自动连接到当前AD域。如果需要,可以指定要绑定的其他容器或域,或者也可以使用PrincipalContext
构造函数的其他重载提供备用凭据

在PageLoad中使用HostingEnvironment.Impersonate()
后问题得以解决: -
示例:
using (HostingEnvironment.Impersonate()) {
GetADUsers();
}
