Hi all, Is it possible to keep encrypted passwords in users file? For e.g. test Cleartext-Password := "test" Service-type = NAS-Prompt-User instead of cleartext can we have encrypted passwords here. Thanks. On Thu, Mar 13, 2008 at 4:32 PM, < freeradius-users-owner@lists.freeradius.org> wrote:

Hi,
I need to set up a RADIUS server that accepts certificates which use SHA-256 as signature algorithm (OID sha256WithRSAEncryption). I have set up a FreeRADIUS 2.0.0-pre2 server to see if this would work out of the box.
After verifying that EAP-TLS authentication works with SHA-1 certificates I switched to SHA-256 certificate that was created with OpenSSL 0.9.8b, the same that FreeRADIUS was compiled against.
Here's a snippet of the log I got from my SHA-256 test:
===== --> verify error:num=7:certificate signature failure rlm_eap_tls: >>> TLS 1.0 Alert [length 0002], fatal decrypt_error TLS Alert write:fatal:decrypt error TLS_accept:error in SSLv3 read client certificate B rlm_eap: SSL error error:0D0C50A1:asn1 encoding routines:ASN1_item_verify:unknown message digest algorithm =====
It would seem there's a problem somewhere. It may very well be in the client I'm using.
So, I'd like to know if FreeRADIUS supports SHA-256 certificates? If it doesn't, is the support for them planned?
thanks in advance, - Hannu

It's not.
People store MD5 or crypt'd passwords when the ONLY authentication they're doing is PAP. i.e. Unix logins, where the user supplies a clear-text password to the authentication system.
For many EAP types, people do NOT store MD5 or crypt'd passwords, because they're useless.
I understand its not very safe nor sane to store passwords in clear text, thats why I wanted to avoid that, however it seems inevitable.
It is safe, sane, and common practice to store passwords in clear text.
I am managing a wired network for some 300 users, its a student dorm and the university owns the network and they require authentication for the ease of management and control. 802.1x felt like the right way to go, because we are planning some wireless access points as well. There are HP's Procurve 2650 switches in use. I choose mysql db backend, because I also created set of PHP scripts, where users can change their passwords and admin can add/del/modify user info. So what can one do to avoid storing passes in clear text or is it sane enough? The server also serves some web pages and dhcp requests.
Ensure that no one has physical access to the system storing the passwords. Ensure that no one has network access to the system storing the passwords.
I would also suggest running the RADIUS server and/or the MySQL server with passwords on a separate machine from the web/dhcp server. That way, if someone breaks into the web server, they won't have access to the passwords.

By ?mutual authentication? I refer to the following authentication process:
1. The client authenticate the server
Give the client the CA cert used to sign the server cert.
2. The server authenticate the client
Create a client cert, signed by the server cert.
3. Only than ? the clients sends username + password using MSCHAPv2
In unlang, set:
update control { EAP-TLS-Require-Client-Cert = yes }
This forces the server to validate the client cert, which is normally not required for TTLS.

If OpenSSL supports it, AND the client supplicant supports it, it should work.
Here's a snippet of the log I got from my SHA-256 test:
===== --> verify error:num=7:certificate signature failure rlm_eap_tls: >>> TLS 1.0 Alert [length 0002], fatal decrypt_error TLS Alert write:fatal:decrypt error TLS_accept:error in SSLv3 read client certificate B rlm_eap: SSL error error:0D0C50A1:asn1 encoding routines:ASN1_item_verify:unknown message digest algorithm
That would seem to be an SSL issue.
So, I'd like to know if FreeRADIUS supports SHA-256 certificates? If it doesn't, is the support for them planned?
FreeRADIUS doesn't support SSL. It uses OpenSSL, which *does* support SSL. So if there are SSL issues, find out why OpenSSL doesn't like the TLS session.

Hi all,
I have 2 questions regarding FreeRADIUS and SNMP:
1/ Is it possible to run 2 FreeRADIUS servers on the same box, with SNMP support activated? I understand it's possible, using distinct values for smux_password parameter.
2/ Connecting FreeRADIUS to Net-SNMP using SMUX is quite easy. Has anyone connected FreeRADIUS with BMC PAtrol agent using SMUX?
Thanks for any answer
Geoff.

And PAP is not very safe and smart way to go as i read it.
For many EAP types, people do NOT store MD5 or crypt'd passwords,

So, crypted passwords are usefull only in web applications? I read a lot lately about, how one should never store passwords in clear text, i guess that applies only to web apps.
I understand its not very
safe nor sane to store passwords in clear text, thats why I wanted to avoid that, however it seems inevitable.
It is safe, sane, and common practice to store passwords in clear text.
I do not have many experience with this, in fact its my first project on the matter.
I am managing a wired network for some 300 users, its a student dorm and the
university owns the network and they require authentication for the ease of management and control. 802.1x felt like the right way to go, because we are planning some wireless access points as well.

That will be no problem, since I'm the only one with physical access.
I would also suggest running the RADIUS server and/or the MySQL server
with passwords on a separate machine from the web/dhcp server. That way, if someone breaks into the web server, they won't have access to the passwords.
I am using VMWare server, so that won't require much work.
