After configuring the guest mode, why does the Windows host access the CIFS share and the prompt box for entering the username and password pops up?

The CIFS share authentication processing policy of the array after the guest mode is configured. If the authentication user name requested by the host does not exist in the local authentication user of the array, the authentication is authenticated by the guest user. If the authentication user name requested by the host is local to the array. It exists in the authentication user and is authenticated by the local user name and password.
When accessing a CIFS share, the Windows host first uses the login user and password to access the array. However, if there is a user with the same username but different password as the Windows host login user, the authentication fails, and the pop-up enters the username and password. Tip box.
After configuring the guest mode in CIFS, you do not need to enter a username and password when accessing the CIFS share. There are two ways to solve this problem:
1. Delete the user with the same username as the Windows host login user in the local authentication user;
2. Change the password of the user with the same login name as the Windows host in the local authentication user, which is the same as the password of the Windows login user.
