Using Crackmapexec - Skills assessments

Hello everyone. I am stuck on the first question of the skills assessments.

i’ve managed to obtain the users list via –rid-brute on DC01.

but neither asreproasting or kerbruteing or password spraying works.

I would like an assistance please.

sed the usernames to filter out the garbage
Than ldap usernames.txt --asreproast asreproast.out
Than hashcat with rockyou.txt

You would get your first username and password
