How to get Password Expiration Date with System.DirectoryServices (C#)
Hi, welcome back,
You may want to get Password Expiration Date for a given user with System.DirectoryServices. You may be tempted to use a code like the following:
DirectoryEntry entry = new DirectoryEntry(path);
object obj = entry.Properties["PasswordExpirationDate"].Value;
DateTime passwordExpirationDate = (DateTime)obj;
But "obj" is always null even if a "net user" command returns a valid password expiration date.
We can check that PasswordExpirationDate is not an available property in DirectoryEntry.Properties.PropertyNames collection.
So we could use a code like the following instead, which works:
DirectoryEntry entry = new DirectoryEntry(path)
ActiveDs.IADsUser native = (ActiveDs.IADsUser)entry.NativeObject;
DateTime passwordExpirationDate = native.PasswordExpirationDate;
I hope this helps.
