FR + AD + Vlans + LDAP help
by Jacob Jarick 17 Apr '07

17 Apr '07

Hello, Im currently trying to configure freeradius to authenticate via a win2k3 server, check the users group and then return a confirmation/ denial + vlan id for the cisco WAP to process. Questions: 1: Is ldap the only way of retreiving the users group/s 2 - Can I talk directly to the ADS using the ldap client (or however its done) instead of setting up a linux openldap server. 3: Does users entry look correct it is ment to disallow people in the group rejects, assign priv students to 1 vlan and students to the other vlan: # !! testing groups DEFAULT LDAP-Group == "rejects", Auth-Type := Reject DEFAULT Auth-Type = ntlm_auth Fall-Through = 1 DEFAULT LDAP-Group == "staff" Service-Type = Framed-User, Tunnel-Type = :1:VLAN, Tunnel-Medium-Type = :1:6, Tunnel-Private-Group-ID = :1:140 DEFAULT LDAP-Group == "students" Service-Type = Framed-User, Tunnel-Type = :1:VLAN, Tunnel-Medium-Type = :1:6, Tunnel-Private-Group-ID = :1:141

O'Reillys Radius Book - Worth buying
by Jacob Jarick 17 Apr '07

17 Apr '07

Hi, Im just getting started with freeradius (trying to nut out dynamic vlans atm) and I was wondering if this book would be a worth while purchase. I had a great experience with O'reillys bind and perl cookbook books. Have any FR users used this book and if so your comments would be appreciated. http://www.oreilly.com/catalog/radius/index.html

LDAP server per realm
by Sean McNamara 17 Apr '07

17 Apr '07

Hello everyone, I'm working on finding a way to define multiple local realms and have each have a unique ldap profile associated with them. We want one associated with a particular realm, and the other to be the catchall/default case. In addition to this, we're also using EAP/TTLS, which may or not complicate the situation.. After googling a bit, I was under the impression that something along the following lines should work: Here are the relevant parts of the the files I modified: in proxy.conf: realm VLS { type = radius authhost = LOCAL accthost = LOCAL } in dictionary: VALUE Auth-Type VU 1 VALUE Auth-Type VLS 2 VALUE Autz-Type VU 1 VALUE Autz-Type VLS 2 in users: DEFAULT Domain == "VLS", Autz-Type := VLS in radiusd.conf: ldap vlsldap { .... set_auth_type = yes } ldap vuldap { .... set_auth_type = yes } authorize { ... ... Autz-Type VLS { vlsldap } vuldap ... } authenticate { ... Auth-Type VLS { vlsldap } vuldap ... } When I attempt to authenticate, regardless of whether I specify a realm or not, it only checks the vuldap servers. Any suggestions would be greatly appreciated! Thank you.. ..Sean.

password encoding flavours
by Stefan Winter 16 Apr '07

16 Apr '07

Hi, currently in the process of migrating to 1.1.6 and the User-Password replacements. We used to have several entries, and for some of them I'm not really sure what to do with... if someone could add some clarity to that it would be highly appreciated! User-Password := something => Cleartext-Password := something Crypt-Password := unixcrypt => Crypt-Password := unixcrypt (these are easy) Crypt-Password := $1$somethingveryweird => SMD5-Password := somethingveryweird (stripping the header, and $1$ meands MD5 with 12-character salt, right?) Crypt-Password := $2a$somethingveryweirdandevenlonger => ????-Password := somethingveryweirdandevenlonger (no clue here... read that $2a$ is a Blowfish crypt, but there is no Blowfish-Password attribute, but apparently right now with 1.1.3 it works anyway?)

RE: Using Client-Ip-Address attribute in preprocess files
by Forrest, Michael E. 16 Apr '07

16 Apr '07

> Nope, Client-IP-Address / Packet-Src-IP-Address don't work as check > items in huntgroups or hints . Well, all I can say is that they Client-IP-Address currently works for me within the huntgroup (haven't tried the hints file). I use it for matching devices and applying policy thereafter from the users file. Am currently on 1.1.5

Requesting help with FR + Dynamic vlans
by Jacob Jarick 16 Apr '07

Hi, here is the current scenario: * school with wireless access * allready uses radius (soon to be freeradius) * freeradius auth's via a win2k3 Active Directory Server * teachers need to be able to log into WAP's a,b,c etc and be automatically assigned to the teachers vlan * priv students need to be able to log into WAP's a,b,c and be assigned to the priv student vlan * norm students simply need to have network access denied from WAP's a,b,c >From what Ive learnt so far today, I need to configure the radius.conf to retrieve the users group from the ADS and then return auth and map group -> vlan / tunnel ID. If some1 could provide me an example or documentation / howto I should read Id be very thankfull. Also if the scenario wasnt clear enough please say so and I will re explain. Thanks alot FR crew.

Multiple REALMS, multiple SQL
by Andrea Cerrito 16 Apr '07

16 Apr '07

Hi to this list, I'm using freeradius from few weeks, and now I need a little help to understand how to configure a proxied configuration to do what I need. My situation: [ Proxy Frontend ] -- REALM ABC >> proxied to [ My Radius Server ] | |- REALM DEF >> proxied to [ My Customer Radius ] | |- REALM GHI >> proxied to [ My Customer Radius ] The data about the realm ABC is stored in a database by another server that I manage, so I keep data without problems. The data about the realm DEF/GHI is not stored at all because I'm not managing the final servers. I cannot store data on the proxy frontend by the simple "sql" configuration because I'll start to write a lot of useless and doubled data (the real configuration is more complex then described before). How can I let the proxy write in a db just the realm DEF and GHI and ignore the realm ABC? I think it can be done in the post-proxy section of the radius.conf... But how? Thank you -- Andrea

Re: The server will carry local authentication first, despite ofproxying or not, is this correct?

No. One of the pieces of information that the SQL queries can return is that the request should be proxied. >> The server *will* process the request through some modules before >> proxying. If that is not "supposed" to happen, please explain how the >> server can proxy the request without doing *some* processing of it. > Maybe we can perform a judgement first,if the server should proxy the request,then send it to home server directly. Try to configure the server so that it proxies requests without looking at them, or without running any kind of local policy that says what requests should be proxied, and where they should be proxied to. You will not succeed. Alan DeKok. -- http://deployingradius.com - The web site of the book http://deployingradius.com/blog/ - The blog

Re: assigning vlan based on NAS and LDAP field?
