DirectoryEntry problem with Credentials (No Impersonation)

Question

User-2127281037 posted

Hi,
I’m using DirectoryEntry to access Active directory inside my Company.
We have 2 OrganizationUnit OU1 and OU2.
We have 2 uers:

• User1 is enabled for OU1
• User2 is enabled both for OU1 and OU2.

I’m logged in Windows with User1, and I need to use User2 to get from Active Directory the list of the Company Users, including both OU1 and OU2.
I’ve used DirectoryEntry constructor with Username, Pwd and AuthType, where I pass User2,
public DirectoryEntry (string path, string username, string password, System.DirectoryServices.AuthenticationTypes authenticationType);

I expected to acquire User2 credentials for getting Users of both the Organization Units, but I continue to retrieve only users for OU1.
I’ve tried also differenct combination for parameter authenticationType but nothing has changed.
Have you any suggestion?
Best regards,
Matteo

I've found a solution impersonating User2 before of invoking the DirectorySearcher.FindAll(), https://www.codeproject.com/Articles/10090/A-small-C-Class-for-impersonating-a-User

Is there another way to do the same thing without impersonating User2?

Thank you,

Matteo
