Ошибка аутентификации Dell OMSA в Ubuntu

Я пытаюсь войти в систему установки Dell OMSA 5 на Dell PowerEdge 2850 под управлением Ubuntu 8.04 LTS x64.

OMSA - 32-битный и пытается загрузить 64-битные модули pam для аутентификации. Какие бы учетные данные я ни использовал для аутентификации через веб-интерфейс OMSA по адресу https://myserver.com:1311 Я всегда получаю сообщение «Ошибка входа ...» и следующие ошибки в /var/log/auth.log

У меня в /etc/pam.d/omauth;

root@server:/var/log# cat /etc/pam.d/omauth

account    required     /lib32/security/pam_unix.so nullok

Я загрузил и распаковал 32-битные модули pam в /lib32/security. Могу ли я как-нибудь пройти аутентификацию для OMSA (но не для чего-то еще)?
