Hello I'm having trouble getting the value of auth_pool of a realm. Realms are defined as regular expressions matched by suffix module against the domain portion of users username. The problem is when the realm regex contains \\ (eg: "~^example\\.com$") the config variable is not found: ++? if ("%{config:realm[%{Realm}].auth_pool}" =~ /%{client-shortname}/i) expand: realm[%{Realm}].auth_pool -> realm[~^example\\.com$].auth_pool WARNING: No such configuration item realm[~^example\\.com$].auth_pool expand: %{config:realm[%{Realm}].auth_pool} -> expand: %{client-shortname} -> idp If I change the realm regex so it has no \\ (eg: "~^example.com$") it is found correctly: ++? if ("%{config:realm[%{Realm}].auth_pool}" =~ /%{client-shortname}/i) expand: realm[%{Realm}].auth_pool -> realm[~^example.com$].auth_pool expand: %{config:realm[%{Realm}].auth_pool} -> idp_pool expand: %{client-shortname} -> idp My config looks something like this: sites-enabled/default: authorize { preprocess suffix # Sets Realm variable files if ("%{config:realm[%{Realm}].auth_pool}" =~ /%{client-shortname}/i) { reject } } ... proxy.conf: home_server idp { type = auth ipaddr = 10.0.99.110 port = 1812 secret = secret response_window = 20 zombie_period = 40 revive_interval = 120 status_check = status-server check_interval = 30 num_answers_to_alive = 3 } home_server_pool idp_pool { type = client-balance home_server = idp } realm "~^example\\.com$" { nostrip auth_pool = idp_pool } clients.conf: client 10.0.99.110 { secret = secret shortname = idp nastype = other } Is this a bug or a safety feature (preventing some sort of injection attacks)? I tried all sorts of combination of single quites, double quotes, no quotes, but to no avail. Am I missing something obvious? Any ideas would be appreciated. -- Matej Vadnjal ANRES
