hi, can any one help me, how to use directoryentry control in .Net (windows application) I have done that years ago using ActiveDirectory. With LDAP should be very similar. This is the code for querying AD public static DirectoryEntry GetDirectoryEntry() { DirectoryEntry de = new DirectoryEntry(); de.Path = " LDAP: / / OU = Domain , DC = YourDomain, DC = com" ; de.AuthenticationType = AuthenticationTypes.Secure; return de to verify whether an user exists or not in AD public bool UserExists( string username) { DirectoryEntry de = GetDirectoryEntry(); DirectorySearcher deSearch = new DirectorySearcher(); deSearch.SearchRoot = de; deSearch.Filter = "(&(objectClass = user) (cn = " + username + "))" ; SearchResultCollection results = deSearch

Because you do not specify anything to the constructor of the DirectorySearcher to provide a domain hint, under the hood ADSI will attempt a serverless bind to domain account, a domain can be inferred. It is easy to fix by providing a DirectoryEntry to the DirectorySearcher constructor that contains the name of the domain to access: LDAP: / / yourdomain
