you can check current login Enviorment.User in Active Directory via Directory Services here is the code: DirectoryEntry adsEntry = new DirectoryEntry ( path  strAccountId  strPassword ); DirectorySearcher adsSearcher = new DirectorySearcher ( adsEntry ); //adsSearcher.Filter = (&(objectClass=user)(objectCategory=person)); adsSearcher . Filter = (sAMAccountName= + strAccountId + ) ; try { SearchResult adsSearchResult = adsSearcher . FindOne (); bSucceeded = true ; strAuthenticatedBy = Active Directory ; strError = User has been authenticated by Active Directory. ; adsEntry . Close (); } catch ( Exception ex ) { // Failed to authenticate. Most likely it is caused by unknown user // id or bad strPassword. strError = ex . Message ; adsEntry . Close (); }
