I have the following code to authenticate. It works, however I have some question about its robustness

The code snipped

DirectoryEntry entry = new DirectoryEntry("LDAP://" + strPath, strDomainAndUsername, strPassword)

tr

Object obj = entry.NativeObject

catch (Exception Ex

throw Ex


For the most part this work, however I noticed some unusual behavior. For example specifying the strDomainAndUsername with a false domain still validates correctly. For example
strDomainAndUsername = @ā€FakeDomain\Usernameā€

The directory call apparently ignores the domain (assuming it is the same domain as the server aka path?

Aside from that I have to wonder what if this user is from another domain in the same forest and is trying to use a local server. Will the entry object propagate the request to the correct domain

If anyone has some insight or perhaps a more robust directory authentication method, please chime in
