====== Freeradius telepítése RHEL/Almalinux 9 (x86_64) rendszeren ======

===== Előkészítés =====

Kiindulásként AlmaLinux 9 (x86_64) operációs rendszer telepítését kell elvégezni. A telepítés minimal telepítés.

===== Telepítést követő lépések =====

Módosítani kell a /etc/dnf/dnf.conf állományt a felesleges gyenge függőségek telepítésének tiltásához:

<code>
# if [ ! -f /etc/dnf/dnf.conf.orig ] ; then cp -a /etc/dnf/dnf.conf /etc/dnf/dnf.conf.orig && echo 'install_weak_deps=False' >> /etc/dnf/dnf.conf ; fi
</code>

Érdemes kikapcsolni a kernel üzenetek megjelenítését

<code>
# grubby --update-kernel=ALL --args=quiet
</code>

A SElinux-ot átmenetileg megengedő módba kell kapcsolni

<code>
# sed -i 's/^SELINUX=.*/SELINUX=permissive/' /etc/selinux/config
</code>

Be kell állítani a rendszer locale-t en_US.UTF-8-ra

<code>
# localectl
</code>

Újra kell indítani a radiusd szolgáltatást

<code>
# systemctl restart radiusd
</code>

Létre kell hozni a DC-n a radiusbind felhasználót akinek a jelszava nem jár le

<code>
# samba-tool user create radiusbind 12345678

# samba-tool user setexpiry radiusbind --noexpiry
</code>

Tesztelhető a szolgáltatás

<code>
# radtest teszt.elek 12345678 127.0.0.1 0 testing123
Sent Access-Request Id 158 from 0.0.0.0:39864 to 127.0.0.1:1812 length 80

==== Kerberos hitelesítés ====

Szükséges csomagok telepítése

<code>
# dnf install freeradius freeradius-utils freeradius-krb5 krb5-workstation
</code>

Hozzunk létre egy felhasználót a DC.n

<code>
# samba-tool user add radius-svc --random-password
User 'radius-svc' added successfully
</code>

Hozzunk létre SPN-t a radius szervernek

<code>
# samba-tool spn add radius/dc1.adomain.lan radius-svc
</code>

Ellenőrizzük az SPN-t

<code>
# ldbsearch -H ldap://localhost -U administrator '(servicePrincipalName=radius/dc1.adomain.lan)' sAMAccountName servicePrincipalName
Password for [ADOMAIN\administrator]:
# record 1
dn: CN=radius-svc,CN=Users,DC=adomain,DC=lan
sAMAccountName: radius-svc
servicePrincipalName: radius/dc1.adomain.lan

# Referral
ref: ldap://adomain.lan/CN=Configuration,DC=adomain,DC=lan

# Referral
ref: ldap://adomain.lan/DC=DomainDnsZones,DC=adomain,DC=lan

# Referral
ref: ldap://adomain.lan/DC=ForestDnsZones,DC=adomain,DC=lan

# returned 4 records
# 1 entries
# 3 referrals
</code>

Ez a lépés nem kötelező . Beállíthatjuk a titkosítást a felhasználói fiók esetében.

<code>
# cat > ~/encryption-mod.ldif <<'EOF'
dn: CN=radius-svc,CN=Users,DC=adomain,DC=lan
changetype: modify
replace: msDS-SupportedEncryptionTypes
msDS-SupportedEncryptionTypes: 24
EOF

# ldbmodify -H ldap://localhost -U administrator ~/encryption-mod.ldif 
Password for [ADOMAIN\administrator]:
Modified 1 records successfully
</code>

Exportáljuk a keytab-ot

<code>
# samba-tool domain exportkeytab /root/radius.keytab --principal=radius/dc1.adomain.lan
Export one principal to /root/radius.keytab
</code>

Ellenőrizzük a keytab tartalmát

<code>
# klist -k -e /root/radius.keytab
Keytab name: FILE:/root/radius.keytab
KVNO Principal
---- --------------------------------------------------------------------------
   2 radius/dc1.adomain.lan@ADOMAIN.LAN (aes256-cts-hmac-sha1-96) 
   2 radius/dc1.adomain.lan@ADOMAIN.LAN (aes128-cts-hmac-sha1-96) 
</code>

Másoljuk be a keytabot a megfelelő helyre és állítsuk be a jogosultságot

<code>
# cp -a /root/radius.keytab /var/lib/radiusd/keytab

# chown radiusd:radiusd /var/lib/radiusd/keytab

# chmod 0600 /var/lib/radiusd/keytab
</code>

Mentsük le az eredeti kerberos konfigurációt

<code>
# [ ! -f /etc/raddb/mods-available/krb5.orig ] && cp -a /etc/raddb/mods-available/krb5 /etc/raddb/mods-available/krb5.orig
</code>

Módosítsuk a konfigurációt

<code>
# cat > /etc/raddb/mods-available/krb5 <<'EOF'
krb5 {
	keytab = ${localstatedir}/lib/radiusd/keytab
	service_principal = radius/dc1.adomain.lan
	pool {
		start = ${thread[pool].start_servers}
		min = ${thread[pool].min_spare_servers}
		max = ${thread[pool].max_servers}
		spare = ${thread[pool].max_spare_servers}
		uses = 0
		lifetime = 0
		idle_timeout = 0
	}
}
EOF
</code>

Engedélyezzük a konfigurációt

<code>
# ln -s ../mods-available/krb5 /etc/raddb/mods-enabled/krb5
</code>

Indítsuk újra a szolgáltatást

<code>
# systemctl restart radiusd
</code>

Teszteljük a kapcsolatot

<code>
