Rather than deal with the never-ending tail-chasing between samba and Microsoft, I've decided to move toward using FreeRadius as a proxy for the Windows radius implementation (formerly IAS, now called NPS). I haven't completed the change, so I'm sorry that I can't tell you how easy it is... but it surely can't be as frustrating as trying to deal with samba always being behind, right?

Here are the complete details of our config: FreeRadius 2.1.8 Setup, configuration, troubleshooting instructions, on CentOS 5.x Goals: o Authentication telnet sessions for Cisco switches against AD for a specific security group (Infrastructure) o Authentication for VPN users using MSCHAP on a sonicwall firewall using a Windows VPN client with L2TP against AD for a specific security group (VPN_Users) Assumptions: SELinux is disabled Access is required on (the default of) 1812/udp and 1813/tcp Install The linux site for the rpm download of freeradius2 is: Create /etc/yum.repos.d/freeradius2.repo: [freeradius2] name=Freeradius2 baseurl=http://people.redhat.com/jdennis/freeradius-rhel-centos enabled=1 gpgcheck=0 Install freeradius2: yum clean all yum install freeradius2 freeradius2-utils freeradius2-ldap Enable FreeRadius to start on boot: chkconfig radiusd on To start the freeRadius service service radiusd start To run the service in debug mode (which you should be doing until everything works): service radiusd stop radiusd -X Quirks If you get an error from the output of radiusd -X along the lines of: Exec-Program output: winbind client not authorized to use winbindd_pam_auth_crap. Ensure permissions on /var/cache/samba/winbindd_privileged are set correctly. (0xc0000022) then the issue is that radiusd doesn't have access to the winbindd_privileged folder. You can fix with: chgrp radiusd /var/cache/samba/winbindd_privileged usermod -a -G wbpriv radiusd ### not this I don't think chmod g+rw /var/cache/samba/winbindd_privileged Configuration See Note that the configuring of SAMBA, kerberos, and adding to the domain should already be done as part of the default Linux install, see h:\is\operating system\Linux\Guide_linux.doc Verify that a user in the domain can be authenticated: wbinfo -a user%password Try the same login with the program, which is what FreeRADIUS will be using: ntlm_auth --request-nt-key --domain=MYDOMAIN --username=user --password=password /etc/raddb/radiusd.conf (see Appendix C) Update max_requests to # users * 256 Add to the end of the auth listen {..} (to permit groups of clients) clients = disambiguate Add to the end of the acct listen {..} (to permit groups of clients) clients = disambiguate In log{..} auth = yes (to log authentication requests) /etc/raddb/huntgroups huntgroups let you restrict which clients are associated with which user. You will need to add each IP of each device that will be using the RADIUS server, and associate it with the correct huntgroup. This will let the /etc/raddb/users file associate the user with the appropriate device: /etc/radbb/huntgroups: Cisco_Huntgroup NAS-IP-Address == 10.100.0.1 Cisco_Huntgroup NAS-IP-Address == 10.100.0.2 Cisco_Huntgroup NAS-IP-Address == 10.100.0.3 ... VPN_Huntgroup NAS-IP-Address == 10.4.1.2 /etc/raddb/modules/ntlm_auth Update the /modules/ntlm_auth module: (to enable ntlm_auth as an authentication method) exec ntlm_auth { wait = yes program = "/usr/bin/ntlm_auth ntlm_auth --request-nt-key --domain=example.com -username=%{mschap:User-Name} --password=%{User-Password}" } /etc/raddb/modules/ldap If this file is missing, you need to install the RPM for freeradius2-ldap. This section is one of the biggest pains to configure, as all of your LDAP strings need to be 100% correct, and they will be very specific to the environment. Of course, update server, identify, password, basedn for your own environment. You will need a user account in AD to permit the bind to LDAP. In this example, that account is in: CN=_useraccount,OU=Service Accounts,OU=Special User Accounts,OU=Enterprise,DC=example,DC=com In this example, the Security groups are located in (or below): OU=Enterprise,DC=example,DC=com ldap { server = "example.com" identity = "CN=_useraccount,OU=Service Accounts,OU=Special User Accounts,OU=Enterprise,DC=example,DC=com" password = secretpassword basedn = "OU=Enterprise,DC=example,DC=com" filter = (&(sAMAccountname=%{%{Stripped-User-Name}:-%{User-Name}})(objectClass=person)) groupmembership_attribute = "memberOf" ldap_connections_number = 5 timeout = 4 timelimit = 3 net_timeout = 1 tls { start_tls = no } dictionary_mapping = ${confdir}/ldap.attrmap edir_account_policy_check = no groupname_attribute = cn groupmembership_filter = "(|(&(objectClass=GroupOfNames)(member=%{control:Ldap-UserDn}))(&(objectClass=GroupOfUniqueNames)(uniquemember=%{control:Ldap-UserDn})))" } Configuration of different virtual sites For this you'll have 3 general sites, default (used mostly for testing on 127.0.0.1), server_cisco (used to AAA the Cisco users), and server_vpn (used to AAA the VPN users). These live in /etc/raddb/sites-available/ inner-tunnel Add: ntlm_auth to the end of the authenticate{..} section default Add: ntlm_auth to the end of the authenticate{..} section server_cisco (see Appendix B) We're going to duplicate the default config, and modify it for that particular virtual server: cp /etc/raddb/sites-available/default /etc/raddb/sites-available/server_cisco Edit server_cisco and change it from server{..} to server server_cisco{..} Since we're not using any of these methods for the Ciscos, in authenticate{..} disable: chap, mschap, suffix, ntdomain, unix, pap Add to the end of the authenticate{..} section: ntlm_auth server_vpn (see Appendix A) cp /etc/raddb/sites-available/server_cisco /etc/raddb/sites-available/server_vpn Edit server_vpn and change it from server server_cisco {..} to server server_vpn {..} To get it to restrict who gets authorized based on the LDAP group, add to authorize {..}: if(Huntgroup-Name == "VPN_Huntgroup") { if(Ldap-Group == "VPN_Users") { ok } else { reject } } Link sites-enabled to sites-available: chown root:radiusd /etc/raddb/sites-available/server_cisco chown root:radiusd /etc/raddb/sites-available/server_vpn cd /etc/raddb/sites-enabled ln -s ../sites-available/server_cisco server_cisco ln -s ../sites-available/server_vpn server_vpn /etc/raddb/clients.conf This defines which individual clients connect to which virtual server, letting you differentiate the server config (including the secret) by client Note: The secret needs to match the secret set on the respective client. Change the secret to an actual secret clients disambiguate { client localhost { ipaddr = 127.0.0.1 secret = testing123 require_message_authenticator = no } client VPN { ipaddr = 10.4.1.2 secret = secret virtual_server = server_vpn } client Cisco { ipaddr = 10.100.0.0 netmask = 16 secret = secret virtual_server = server_cisco nastype = cisco }} /etc/raddb/users This file determines which AAA is done against which device and associates the defined huntgroups with the type of AAA #testuser Huntgroup-Name == Cisco_Huntgroup, Cleartext-Password:="testpass" # Service-Type:=NAS-Prompt-User,cisco-avpair:="shell:priv-lvl=15" DEFAULT Huntgroup-Name == Cisco_Huntgroup, Auth-Type:=ntlm_auth, Ldap-Group == "Infrastructure" Service-Type:=NAS-Prompt-User,cisco-avpair:="shell:priv-lvl=15" DEFAULT Huntgroup-Name == VPN_Huntgroup, Ldap-Group == "VPN_Users" /etc/raddb/modules/mschap mschap { ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --username=%{mschap:User-Name} --domain=%{mschap:NT-Domain:-example.com} --challenge=%{mschap:Challenge:-00} --nt-response=%{mschap:NT-Response:-00}" } - List info/subscribe/unsubscribe?
