Я пытаюсь настроить компьютер с Ubuntu 18.04 и присоединить его к домену Active Directory. На всех других системах, которые я использовал, я мог сделать

# kinit -kt /path/to/keytab my_username
# realm join ad.example.com

Однако в Ubuntu 18.04 кажется, что команда realm не видит билет Kerberos:

# kinit -kt /path/to/keytab my_username
# realm join --verbose ad.example.com
 * Resolving: _ldap._tcp.ad.example.com
 * Performing LDAP DSE lookup on: 10.A.B.150

 ! Couldn't authenticate as: Administrator@AD.EXAMPLE.COM: Preauthentication failed
adcli: couldn't connect to ad.example.com domain: Couldn't authenticate as: Administrator@AD.EXAMPLE.COM: Preauthentication failed
 ! Failed to join the domain

Что здесь может происходить?
