I don't know about computer accounts, but this DoS is not possible if you are using service principals. Active Directory doesn't allow login for service principals, and keytab are only useful to decrypt tickets. Making an ldap query to AD, you can get things like dNSHostName: sist03lnx.domain.com userPrincipalName: HOST/[EMAIL PROTECTED] servicePrincipalName: HTTP/sist03lnx.domain.com servicePrincipalName: HTTP/sist03lnx In this case, only HOST/sist03lnx keytab works with `kinit -k`. If you attempt to get a TGT with the other principals, you get nothing.
