Hello to the whole list, I'm experiencing a big and strange problem with the hints file. First I'll explain what I need to do. The users can access only to the machines of some companies OR to all the machine of the same kind, for example I could have user FOO who can have access only to the machines of customer custA and custB and is able to manage all the firewalls of all the customers. To do that I implemented a set of rules in hints which 1) Set the permissions for the logging user 2) Recognize the type of machine which the user is trying to access 3) Check the permissions relating the customers and sets the (custom) attribute itfgrant to "ok" if the user can log onto that machine 4) Check the permissions relating the type of machine and sets the (custom) attribute itfgrant to "ok" if the user can log onto that machine* * Then in the users file I check that attribute (itfgrant) along with the password to grant the access. The problem is that for each user the first login after the starting of the server is evaluated in the right way, with the right permissions. All the successive logins carry the same result as the first one! In other words if the first login resulted in a Access-Accept then EVERY successive login from that user will result in a Access-Accept. The same thing happens if the first login resulted in a Access-Reject. Restarting the server fixes the behaviour only for another login, then I have to restart the server again. Glossary: itfcliente contains the permissions for a given user itfgrant is used to grant access itfAll-* are used like booleans to give permissions to all the machines of a kind itfclient contains the name ho the customer which the machine belongs (like an huntgroup) Here is the hints file #START OF CONTENTS (it starts on the line numbered 37) # declaration of users permissions DEFAULT User-Name=="denABcfw" itfcliente+="clienteA", itfcliente+="clienteB", itfAll-cisco="yes", itfAll-fw="yes", itfAll-win="yes", Fall-Through:="yes" DEFAULT User-Name=="denf" itfAll-fw="yes", Fall-Through:="yes" DEFAULT User-Name=="denBC" itfcliente+="clienteB", itfcliente+="clienteC", Fall-Through:="yes" DEFAULT User-Name=="maxA" itfcliente+="clienteA", Fall-Through:="yes" ###### Detecting the customer DEFAULT Nas-Ip-Address =~ "10\.10\.8\.[0-2]?[0-9]*" itfclient:="clienteA", Fall-Through:="yes" DEFAULT Nas-Ip-Address =~ "10\.10\.9\.[0-2]?[0-9]*" itfclient:="clienteB", Fall-Through:="yes" DEFAULT Nas-Ip-Address =~ "10\.10\.10\.[0-2]?[0-9]*" itfclient:="clienteC", Fall-Through:="yes" ###### Detecting the kind of machine DEFAULT Nas-Ip-Address == 10.10.8.1 itftype="win", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.9.1 itftype="win", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.10.1 itftype="win", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.8.2 itftype="lin", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.9.2 itftype="lin", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.10.2 itftype="lin", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.8.3 itftype="cisco", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.9.3 itftype="cisco", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.10.3 itftype="cisco", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.8.4 itftype="fw", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.9.4 itftype="fw", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.10.4 itftype="fw", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.8.5 itftype="voip", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.9.5 itftype="voip", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.10.5 itftype="voip", Fall-Through:="yes" # Match itfcliente with the customer customer (itfclient) DEFAULT itfcliente=="%{itfclient}" itfgrant:="ok", Fall-Through:="yes" # Match with the type of machine DEFAULT itftype=="cisco", itfAll-cisco=="yes" itfgrant:="ok", Fall-Through:="yes" DEFAULT itftype=="fw", itfAll-fw=="yes" itfgrant:="ok", Fall-Through:="yes" DEFAULT itftype=="win", itfAll-win=="yes" itfgrant:="ok", Fall-Through:="yes" DEFAULT itftype=="lin", itfAll-lin=="yes" itfgrant:="ok", Fall-Through:="yes" DEFAULT itftype=="voip", itfAll-cisco=="voip" itfgrant:="ok" #END OF CONTENTS And here come the users file # this one has access to customers A and B, and to all the cisco equipment, firewalls and windows machines denABcfw Cleartext-Password:="pippo", itfgrant=="ok" Fall-Through:="yes" # this one has access to all the firewall and nothing else denf Cleartext-Password:="pippo", itfgrant=="ok" Fall-Through:="yes" # this user has access only to the customers B and C denBC Cleartext-Password:="pippo", itfgrant=="ok" Fall-Through:="yes" # this one can access only to the customer A maxA Cleartext-Password:="pippo", itfgrant=="ok" Fall-Through:="yes" Here's the output of freeradius -X with some tests FreeRADIUS Version 2.1.10, for host i486-pc-linux-gnu, built on Nov 17 2010 at 04:06:04 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.
