| Аутентификация в Postgres Pro с помощью Kerberos | Используя протокол GSSAPI | 2022-11-29T16:21:00+05:00 |

Установка Kerberos и Postgres Pro
Для начала, необходимо установить Postgres Pro и Kerberos. На машину с Postgres Pro Kerberos устанавливается также, как и на клиента.
Конфигурация сервера Kerberos
Добавление принципиала Postgres Pro
kadmin.local
addprinc <username>
addprinc postgres
addprinc postgres/<pg-hostname>
q
Экспорт субъекта-службы
ktutil
add_entry -password -p postgres/<pg-hostname>@<DOMAIN.NAME> -k 1 -e aes256-cts-hmac-sha1-96
wkt postgres.keytab
q
Перенос субъекта-службы на сервер Postgres Pro
Перенести keytab можно как угодно, главное, чтобы он находился в папке с конфигурационными файлами Postgres Pro. Я перенесу с помощью команды scp:
scp postgres.keytab postgres@<pg-hostname>:/var/lib/pgpro/std-13/data/
Конфигурация сервера Postgres Pro
Включение ранее перенесённого keytab
ktutil
read_kt postgres.keytab
q
Изменение конфигруационного файла Postgres Pro
krb_server_keyfile = 'postgres.keytab'
listen_addresses = 'localhost, <pg-ip>'
# /var/lib/pgpro/std-13/data/postgresql.conf
Разрешение подключения
hostgssenc all postgres localhost/32 gss include_realm=0
hostgssenc <database> <username> <client-ip>/32 gss include_realm=0
# /var/lib/pgpro/std-13/data/pg_hba.conf
Получение тикета от Kerberos
kinit postgres
Конфигурация клиента
Получение тикета от Kerberos
kinit <username>
Подключение к Postgres Pro
psql -d <database> -h <pg-hostname> -U <username>
