Test Environment: SERV-U 4.1 & 5.0 & 5.004 Test Result: Test By Test Method: Enter a clear text submission, then copy the hash in the text box below, paste into the servadaemon.ini file of Serv-U, and then Restart the Serv-U service. That is to test if the password is correct. When the test is found, the account added directly in the INI file, there is no need to launch the Serv-U, but if you add some virtual directories, the virtual directory requires the server to restart. In addition, if INI is modified, the error information is filled in, causing that the user cannot log in. If the service is not restarted, no matter how it is again modified, the user does not log in normally, the solution: Modify the user name, and Correct the error configuration information to log in.
