C# 将用户添加到 Active Directory - 指定给目录服务的属性语法无效

Question

我在尝试在事件目录中创建新用户时遇到问题。我按照此 link 中提供的步骤进行操作用于使用 PrincipalContext(异常(exception)情况是，当他们被雇用并进入系统时，我一次只处理一个用户，而不是多个用户，因此不需要循环)。我也在使用 UserPrincipal Extender。

这是我的代码:

protected void CreateUserPE()
{
    try
    {
        PrincipalContext userCtx = new PrincipalContext(ContextType.Domain, DomainFQDN, DomainFull);
        string UserName = txtFirstName.Text.ToLower() + " " + txtLastName.Text.ToLower();
        string password = "superSecretPassword";

        UserPrincipalsEx newUser = new UserPrincipalsEx(userCtx, UserName, password, true);
        newUser.SamAccountName = txtFirstName.Text.ToLower() + "." + txtLastName.Text.ToLower();
        newUser.UserPrincipalName = txtFirstName.Text.ToLower() + "." + txtLastName.Text.ToLower() + "@rasm.com";
        newUser.EmployeeId = txtEmpID.Text;
        newUser.LastName = txtLastName.Text;
        newUser.GivenName = txtFirstName.Text;
        newUser.DisplayName = txtFirstName.Text + " " + txtLastName.Text;
        newUser.Name = txtFirstName.Text + " " + txtLastName.Text;
        newUser.SetPassword(password);
        newUser.HomePostalAddress = txtAddress.Text + ", " + txtCity.Text + ", " + txtState.Text + ", " + txtZip.Text;
        newUser.CountryName = txtCountry.Text;
        newUser.HomePhone = txtHomePhone.Text;
        newUser.MobilePhone = txtMobilePhone.Text;
        newUser.DateOfBirth = txtDOB.Text;
        newUser.EmergencyContact = txtEmergencyCnt.Text;
        newUser.EmergencyPhone = txtContactPhone.Text;
        newUser.Relationship = ddlRelationship1.SelectedItem.ToString();
        newUser.EmergencyContact2 = txtEmergencyCnt2.Text;
        newUser.EmergencyPhone2 = txtContactPhone2.Text;
        newUser.Relationship2 = ddlRelationship2.SelectedItem.ToString();
        newUser.EyeColor = ddlEyeColor.SelectedItem.ToString();
        newUser.HairColor = ddlHairColor.SelectedItem.ToString();
        newUser.Height = txtHeight.Text;
        newUser.Weight = txtWeight.Text;
        newUser.Gender = ddlGender.SelectedItem.ToString();
        newUser.PersonalEmail = txtPersonalEmail.Text;
        newUser.PassportExpires = txtPassportExp.Text;
        newUser.HomeBase = ddlHomeStation.SelectedItem.ToString();
        newUser.WorkLocation = txtWorkLocation.Text;
        newUser.PID = txtPID.Text;
        newUser.Team = txtTeam.Text;
        newUser.Manager = "CN=" + txtSupervisor.Text + "," + DomainFull;
        newUser.Title = ddlJobTitle.SelectedItem.ToString();
        newUser.JobCode = txtJobCode.Text;
        newUser.PLC = txtPLC.Text;
        newUser.BPLC = txtBPLC.Text;
        newUser.Specialty = txtSpecialty.Text;
        newUser.Position = txtPosition.Text;
        newUser.DateOfHire = txtDOH.Text;
        newUser.DateOnContract = txtDOC.Text;
        newUser.TaskOrder = ddlTaskOrder.SelectedItem.ToString();
        newUser.Classification = ddlClass.SelectedIndex.ToString();
        newUser.Section = txtSection.Text;
        newUser.GatePass = txtGatePass.Text;
        newUser.GatePassExpires = txtGatePassExp.Text;
        newUser.WorkPhone = txtWorkPhone.Text;
        newUser.CompanyEmail = txtCompEmail.Text;
        newUser.aKOEmail = txtMilEmail.Text;
        newUser.aKOSponsor = txtMilEmailSp.Text;
        newUser.CACSponsor = txtCacSponsor.Text;
        newUser.CACSponsorEmail = txtCacSponsorEmail.Text;
        newUser.CacCardExpires = txtCacExpires.Text;
        newUser.Enabled = true;
        newUser.ExpirePasswordNow();
        newUser.Save();
        newUser.Dispose();
    }
    catch
    {

    }
}

程序一直执行到 newUser.Save()，然后在 catch 语句中抛出以下错误:

System.DirectoryServices.AccountManagement.PrincipalOperationException was caught
  HResult=-2146233087
  Message=The attribute syntax specified to the directory service is invalid.

我哪里错了。

您不能使用 null 或空更新属性。我个人不喜欢具有虚拟值的解决方案。如果您使用的是上下文原则，只需简单地检查 null 或 empty 并且在这种情况下不要更新:

if (!string.IsNullOrEmpty(txtbox.Text)){ newUser.attributeName = txtbox.Text}

如果您使用的是目录条目而不是用户上下文，您可以这样做:

string adPath = "LDAP://server.domain.com/CN=John,CN=Users,dc=domain,dc=com";
DirectoryEntry userEntry = new DirectoryEntry(adPath);
if (txtBox.text == "")
{
    userEntry.Properties["proppertyName"].Clear();
}
else if (!string.IsNullOrEmpty(txtBox.text))
{
    userEntry.Properties[attribute.Key].Value = txtBox.text;
}
// dont do a thing when txtBox.Text is empty

它看起来像更多的代码，但是如果你有一个包含所有属性的列表，那么为它制作一个 foreach 循环会容易得多:

private void UpdateEntryAttributes(DirectoryEntry entry, Dictionary<string, string> attributes)
{
    foreach (KeyValuePair<string, string> attribute in attributes)
    {
    entry.Properties[attribute.Key].Value = attribute.Value;

    if (attribute.Value == "")
    {
        entry.Properties[attribute.Key].Clear();
    }
    else if (!string.IsNullOrEmpty(attribute.Value))
    {
        entry.Properties[attribute.Key].Value = attribute.Value;
    }
}
