如何获取C#中的Active Directory用户帐户属性
其中包括以下代码(包括extensionAttribute1
- 15
)
// get whatever attributes are available
List<string> allAttributes = new List<string>();
var context = new DirectoryContext(DirectoryContextType.Forest, "mydomain.com");
using (var schema = System.DirectoryServices.ActiveDirectory.ActiveDirectorySchema.GetSchema(context)) {
var userClass = schema.FindClass("user");
foreach (ActiveDirectorySchemaProperty property in userClass.GetAllProperties()) {
allAttributes.Add(property.Name);
}
}
我可以成功获得所有AD属性的完整列表, 这些属性中的大多数(尤其是ExtensionAttribute
s )都不存在:
SearchResultCollection results;
DirectoryEntry de = new DirectoryEntry("LDAP://RootDSE");
DirectorySearcher ds = new DirectorySearcher("LDAP://" + de.Properties["defaultNamingContext"][0].ToString());
ds.Filter = "(&(objectCategory=User)(objectClass=person))";
results = ds.FindAll();
foreach (SearchResult sr in results) {
Console.WriteLine(sr.Properties["extensionAttribute1"][0].ToString()); // == null
}
我在做什么错?
I can successfully get a complete list of all AD Attributes with the following code (including things like extensionAttribute1
- 15
)
// get whatever attributes are available
List<string> allAttributes = new List<string>();
var context = new DirectoryContext(DirectoryContextType.Forest, "mydomain.com");
using (var schema = System.DirectoryServices.ActiveDirectory.ActiveDirectorySchema.GetSchema(context)) {
var userClass = schema.FindClass("user");
foreach (ActiveDirectorySchemaProperty property in userClass.GetAllProperties()) {
allAttributes.Add(property.Name);
}
}
However, when I retrieve a user account with the following code, most of these attributes (especially the extensionAttribute
s) are not present:
SearchResultCollection results;
DirectoryEntry de = new DirectoryEntry("LDAP://RootDSE");
DirectorySearcher ds = new DirectorySearcher("LDAP://" + de.Properties["defaultNamingContext"][0].ToString());
ds.Filter = "(&(objectCategory=User)(objectClass=person))";
results = ds.FindAll();
foreach (SearchResult sr in results) {
Console.WriteLine(sr.Properties["extensionAttribute1"][0].ToString()); // == null
}
What am I doing wrong?

正常的。属性仅在具有值时才会返回。如果属性没有值,则根本不会返回。
That is normal. Attributes are only returned if they have a value. If an attribute does not have a value, it is not returned at all.
