Virtual server pre-proxy section not executed for proxied authentication on v3.0.18 and above

1 Oct 2019

      I've been attempting to upgrade some FreeRadius servers that have been following the v3.0.x line. Normally taking the existing running configuration from one minor version and applying to the next has just worked, however attempting to go from 3.0.17 to 3.0.18 (or 3.0.19 or the latest head) and it appears that the pre-proxy section of a virtual server isn't called when proxying authentication requests and the packet is sent straight to the remote radius server. Nothing in the change log or proxy.conf etc jumps out at me as indicating a deliberate change in this area.

I can reproduce the problem by applying a minimal realm/home_server_pool/home_server/virtual server combination to an out-of-the-box new install of each version so I don't think it is caused by carrying over some old/incompatible configuration from an old version, however it's quite possible my understanding of how proxying is suppose to work is wrong and my configuration worked by accident rather than design and later versions have tightened up the behaviour.

Two full outputs from radiusd -X included at end of the email.

An a minimal example to reproduce the problem to proxy.conf I've added:

home_server example_home_server {
  ipaddr = 1.2.3.4
  port = 1812
  secret = password
}

home_server_pool example_home_server_pool {
  home_server = example_home_server
  virtual_server = example-virtual-server
}

realm example.net {
  auth_pool = example_home_server_pool
}

And added a file to sites-enabled with:

server example-virtual-server {
  pre-proxy {
    # just as a simple example of something that could be done here, would normally add/modify attributes
    reject
  }
}

Up to and including 3.0.17 I see the authorize section completes and then the pre-proxy section get called and, with my simple example, a reject gets sent back to the client:

(0)     [pap] = noop
(0)   } # authorize = updated
(0) server example-virtual-server {
(0)   # Executing section pre-proxy from file /opt/freeradius-server-3.0.17/etc/raddb/sites-enabled/example-virtual-server
(0)     pre-proxy {
(0)       [reject] = reject
(0)     } # pre-proxy = reject
(0) }

However on 3.0.18 and above it goes straight from completing the authorize section to sending the packet to the remote radius server. It does appear to know about the virtual server as on failure to proxy the request it looks for a Post-Proxy-Type Fail-Authentication in the virtual server

(0)     [pap] = noop
(0)   } # authorize = updated
(0) Starting proxy to home server 1.2.3.4 port 1812
(0) Proxying request to home server 1.2.3.4 port 1812 timeout 30.000000

(0)   User-Name = "fred"
(0)   Calling-Station-Id = "11-22-33-44-55-66"

(snip)
