Greetings,
i managed to work around this issue, although I still believe this is not the
correct behavior and should be treated as a bug. More to that later.
I changed the method "_isSwitchSupported" in the File
/usr/local/pf/lib/pf/radius.pm like below:
sub _isSwitchSupported {
my ($self, $args) = @_;
my $logger = $self->logger;
if ($args->{'connection_type'} == $WIRED_MAC_AUTH) {
return $args->{'switch'}->supportsWiredMacAuth();
} elsif ($args->{'connection_type'} == $WIRED_802_1X) {
return $args->{'switch'}->supportsWiredDot1x();
} elsif ($args->{'connection_type'} == $WIRELESS_MAC_AUTH) {
# TODO implement supportsWirelessMacAuth (or supportsWireless)
$logger->trace("Wireless doesn't have a supports...() call for now,
always say it's supported");
return $TRUE;
} elsif ($args->{'connection_type'} == $WIRELESS_802_1X) {
# TODO implement supportsWirelessMacAuth (or supportsWireless)
$logger->trace("Wireless doesn't have a supports...() call for now,
always say it's supported");
return $TRUE;
}
return $TRUE;
}
I'm aware that this is a really dirty workaround but it's the only thing that
helped. Afterwards I edited the file
/usr/local/pf/sbin/httpd.aaa-docker-wrapper to include the lib folder from
packetfence:
args="$args -v/usr/local/pf/lib/:/usr/local/pf/lib/
-v/usr/local/pf/conf/:/usr/local/pf/conf/
-v/usr/local/pf/var/conf/:/usr/local/pf/var/conf/ -p 100.64.0.1:7070:7070 -p
127.0.0.1:7070:7070"
After a restart of packetfence-httpd.aaa the Fortigate Auth got accepted and
I'm able to use the captive portal.
Now to my thoughts:
I think the RADIUS Request gets treated incorrectly as there is no
Connection-Type being sent with the original Request (I've looked at the
wireshark trace of the requests). I've compared the trace to a real CLI-Request
from a Cisco switch and the difference is that the FortiGate fills the
Connect-Info field with the value "web-auth" whereas the Cisco doesn’t attach
this field at all. Also, the Fortigate provides the Called-Station-Id +
Calling-Station-Id -> this should be treated like a normal radius
authentication but gets classified as some kind of cli-auth.
I've opened a bug-report on github, but maybe its only some kind of
misunderstanding from my side:
https://github.com/inverse-inc/packetfence/issues/7402
I'd be happy to provide packet-traces or additional logs if needed.
Mit freundlichen Grüßen

Betreff: AW: Issues doing captive-portal auth with FortiGate and FortiAPs
Greetings,
I troubleshooted some more and found out, that I receive the following message
in packetfence.log:
Dec 2 10:19:42 packetfence httpd.aaa-docker-wrapper[110944]: httpd.aaa(1855)

I then checked the code in /usr/local/pf/lib/pf/radius.pm and found the
following lines:
sub _isSwitchSupported {
my ($self, $args) = @_;
my $logger = $self->logger;

} elsif ($args->{'connection_type'} == $WIRED_802_1X) {
return $args->{'switch'}->supportsWiredDot1x();
} elsif ($args->{'connection_type'} == $WIRELESS_MAC_AUTH) {
# TODO implement supportsWirelessMacAuth (or supportsWireless)
$logger->trace("Wireless doesn't have a supports...() call for now,
always say it's supported");
return $TRUE;
} elsif ($args->{'connection_type'} == $WIRELESS_802_1X) {
# TODO implement supportsWirelessMacAuth (or supportsWireless)
$logger->trace("Wireless doesn't have a supports...() call for now,

return $TRUE;
}
}
=item * _switchUnsupportedReply - what is sent to RADIUS when a switch is
unsupported
=cut
sub _switchUnsupportedReply {
my ($self, $args) = @_;
my $logger = $self->logger;
$logger->warn("(" . $args->{'switch'}->{_id} . ") Sending REJECT since
switch is unsupported");
$args->{'switch'}->disconnectRead();
$args->{'switch'}->disconnectWrite();
return [$RADIUS::RLM_MODULE_FAIL, ('Reply-Message' => "Network device does
not support this mode of operation")]; }
If I read this correctly, the FortiAP sends CLI-Access as connection type but
as it seems, this is not supported in radius.pm. Is this a bug?

Betreff: [PacketFence-users] Issues doing captive-portal auth with FortiGate
and FortiAPs
Greetings,
we are currently testing out packetfence captive-portal auth in connection with
FortiGate and FortiAPs. I followed the instructions from the following mailing
list post:
https://sourceforge.net/p/packetfence/mailman/packetfence-users/thread/0b65c462-4c0c-24fe-5e10-405102e8de36%40inverse.ca/#msg36349338
The redirection from the access-point to the captive portal works just fine and
I successfully log in and get my role. Afterwards (as described in the post
above), the FortiGate/FortiAP is trying to authenticate against PacketFence but
fails with the following log message:
User-Name = "a0:51:0b:6a:47:b2"
User-Password = "******"
NAS-IP-Address = 10.255.20.19
Service-Type = Login-User
Framed-IP-Address = 10.23.87.5
Called-Station-Id = "d4:76:a0:d2:b9:50:ASAP-Gast (Testing)"
Calling-Station-Id = "a0:51:0b:6a:47:b2"

Connect-Info = "web-auth"
Fortinet-Vdom-Name = "root"
Fortinet-SSID = "ASAP-Gast (Testing)"
Fortinet-AP-Name = "PU221ETF21002253"

PacketFence-Radius-Ip = "10.20.10.55"
Module-Failure-Message = "rest: Server returned:"
Module-Failure-Message = "rest:
{\"control:PacketFence-Request-Time\":1669912145,\"control:PacketFence-IfIndex\":\"external\",\"control:PacketFence-Connection-Type\":\"CLI-Access\",\"control:PacketFence-Switch-Id\":\"10.255.20.19\",\"control:PacketFence-Authorization-Status\":\"allow\",\"control:PacketFence-Switch-Mac\":\"d4:76:a0:d2:b9:50\",\"control:PacketFence-Switch-Ip-Address\":\"10.255.20.19\",\"Reply-Message\":\"Network

SQL-User-Name = "a0:51:0b:6a:47:b2"
I first thought that this has something to do with the CLI-Access not enabled
on the corresponding switch but I double checked, both flags (for External
Portal Enforcement and CLI/VPN Access) are enabled. Is there something I'm
missing? The debug log from radiusd didn't yield any results either.
Thank you in advance!
