Hello, friend!
Problem 1. Only Machine-machine accounts can use -kt to log in?
Answer: The kinit-kt command can also be used for man-machine accounts.
Problem 2. error "kinit: password incorrect while getting initial credentials"
1. The error cause is incorrect user name/password. Perform the following steps to locate the fault:
2. Check whether the downloaded keytab file fails to be authenticated because the man-machine user has expired.
3. Check whether the authenticated client matches and is the latest.
Whether the user has changed the password.
Hope this helps!
