Am going to be direct assuming you have already gotten the credentials for user f.frizzle.
This is because the problem starts here.

I face permission denied on ssh f.frizzle@frizz.htb -K

Change the host File to 

10.10.11.60    frizzdc.frizz.htb frizz.htb (The order is important!!!! frizzdc.frizz.htb  have to be in the first Line)

then Synchron the Time with the DC

ntpdate frizzdc.frizz.htb

Use kinit to get the Ticket

kinit f.frizzle@FRIZZ.HTB

Check you Ticket is Save in Cache

klist

ssh f.frizzle@frizz.htb -K

Edit:

Whe have to add some Entrys at our local Mashine  in the /etc/krb5.conf File !!!

[domain_realm]
    .frizz.htb = FRIZZ.HTB
    frizz.htb = FRIZZ.HTB

[libdefaults]
    default_realm = FRIZZ.HTB
    dns_lookup_realm = false
    dns_lookup_kdc = true
    ticket_lifetime = 24h
    forwardable = true

[realms]
    FRIZZ.HTB = {
        kdc = FRIZZDC.FRIZZ.HTB
        admin_server = FRIZZDC.FRIZZ.HTB
        default_domain = FRIZZ.HTB
    }
