kinit password incorrect while getting initial credentials

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.
