我正在创建一个 WCF 服务来检索和更新/创建 ADPerson对象，但遇到了障碍。我创建了一个扩展类来管理扩展属性（交付的架构属性，但不在默认帐户管理类属性集中）。检索或更新这些扩展属性没有问题，但是当我尝试在 AD 中创建新的人员对象时，我收到约束违规
System.DirectoryServices.DirectoryServicesCOMException：发生约束冲突。
我目前正在 Windows 8.1 桌面上的 Visio 2013 中以调试模式对此进行测试。代码如下。任何人都可以提供的任何提示或见解都非常感谢。
希望下面的代码记录得足够好并且有意义。提前致谢！
更新：我应该更清楚。我很确定它是扩展属性的原因是，当我在调用代码中注释掉那些设置这些属性的行（现在在下面的代码部分中注释）时，它将创建没有错误的对象。
这是我的调用代码：
....other code.....
PrincipalContext pc = null;
try {
pc = new PrincipalContext(ContextType.Domain, MyProject.ADAccountService.Properties.Settings.Default.Domain, MyProject.ADAccountService.Properties.Settings.Default.PeopleDN, MyProject.ADAccountService.Properties.Settings.Default.AdminAcct, MyProject.ADAccountService.Properties.Settings.Default.AdminPW);
}
catch (Exception e) {
defaultLogger.Warn(MyProject.ADAccountService.App_GlobalResources.Messages.PrincipalContextCreateFail, e);
// Application.Exit();
}
....other code looking for whether ADObject already exists...
// Create the new UserPrincipal object
if (!newADPerson.personExists) {
using (ADeXt userNew = new ADeXt(pc)) {
string randomPassword = System.Web.Security.Membership.GeneratePassword(20, 4);
if (newADPerson.officePhone != null && newADPerson.officePhone.Length > 0) { userNew.VoiceTelephoneNumber = newADPerson.officePhone; }
if (newADPerson.department != null && newADPerson.department.Length > 0) { userNew.department = newADPerson.department; } //offending codeline

if (newADPerson.officeLocation != null && newADPerson.officeLocation.Length > 0) { userNew.physicalDeliveryOfficeName = newADPerson.officeLocation; } //offending codeline
if (newADPerson.isEmployee) {
//if an employee and (newADPerson.script == null) use default value from global project settings
userNew.ScriptPath = newADPerson.script ?? MyProject.ADAccountService.Properties.Settings.Default.defaultScript;
}
if (newADPerson.lastName != null && newADPerson.lastName.Length > 0) { userNew.Surname = newADPerson.lastName; }
if (newADPerson.firstName != null && newADPerson.firstName.Length > 0) { userNew.GivenName = newADPerson.firstName; }
if (newADPerson.emplID != null) { userNew.EmployeeId = newADPerson.emplID; }
if (newADPerson.displayName != null && newADPerson.displayName.Length > 0) { userNew.DisplayName = newADPerson.displayName; }
userNew.SamAccountName = AccountID;
userNew.Name = AccountID;
userNew.UserPrincipalName = AccountID + MyProject.ADAccountService.Properties.Settings.Default.ExchangeAddress;
try {
userNew.Save();
userNew.SetPassword(randomPassword);
}
catch (Exception e) {
pc.Dispose();
}
}
}
扩展类代码：
