Merge e3e13af922 into 4e8ea2d7f0

Добавлен вызов pam_acct_mgmt() после pam_authenticate() для проверки
прав доступа на уровне PAM (HBAC, истечение пароля, блокировка учётки)
Исправлена передача реального username в pam_start() вместо '3proxy@'

---

Added pam_acct_mgmt() call after pam_authenticate() to enable PAM
account checks (HBAC, password expiration, account lockout).
Fixed pam_start() to pass actual username instead of hardcoded '3proxy@'
Tested with FreeIPA 4.12 + SSSD Rocky Linux 9
