We have created an application that will authenticate Active Directory users to Laserfiche through a Webservice using the Laserfiche.RepositoryAccess.Login() method. If we pass local Laserfiche credentials it works perfectly. If we pass DOMIN\Username and password we get the 9010 Invalid username and or password error. We are currently using Laserfiche 9.2. If we try to connect to the Laserfiche Client and uncheck use Windows Authentication and enter DOMIN\Username and password it works. We use this similar code at another client site and it works fine. Any idea's. Also there is no security logs on the Laserfiche Server.
