Дано FreeBSD 6.1-RELEASE-p11, роутер Cisco 1601 - IOS 1600 Software (C1600-Y-M), Version 12.0(28), RELEASE SOFTWARE (fc2). Установленный из коллекции портов FreeRADIUS Version 1.1.3.
Нужно: авторизация пользователей.
Решил пока не связываться с регистрацией пользователей в MySQL или LDAP, а использовать системную авторизацию, при которой пароли читаются из /etc/spwd.db.

# PAP module to authenticate users based on their stored password

# Supports multiple encryption schemes
# clear: Clear text
# crypt: Unix crypt
# md5: MD5 ecnryption
# sha1: SHA1 encryption.
# DEFAULT: crypt
pap {
encryption_scheme = md5
}Вместо стоявшей схемы crypt прописал md5, так как во FreeBSD используется шифрация паролей по алгоритму md5.

# Some systems (e.g. RedHat Linux with pam_pwbd) can

# you should set the cache value to 'yes', and set

#
# Define the locations of the normal passwd, shadow, and

#
# 'shadow' is commented out by default, because not all
# systems have shadow passwords.
#
# To force the module to use the system password functions,

# This is required for some systems, like FreeBSD,
