Hi Markus and Christian,

I had the same problems weeks ago...(including the same error messages) I just 
configured the PFSENSE CAPTIVE PORTAL and SQUID to authenticate at IAS (windows 
2003),
After a painfull check-up, i found that.. It was the IAS POLICY that was 
wrong.. Both, captive portal and SQUID, send authentication information to IAS 
in PAP format with no encryption at all  :(
So i just changed some features at IAS POLICY and it worked!

Things to check at Microsoft IAS:

1. At IAS-> RADIUS CLIENT: be sure that you have the PFSENSE IP address here!
2. at IAS, after creating the PFSENSE address, enter in the properties of it 
and check if the CLIENT VENDOR is set to use RADIUS STANDARD. I'm supposing 
that your shared-key is OK, as you said...
3. at IAS, REMOTE ACCESS POLICY, check at the AUTHENTICATION TAB if Unencrypted 
authentication is lit.
4. at IAS, at the ENCRYPTION TAB, check if the NO ENCRYPTION is Lit.

Well, i hope it can help you guys...

Sincerely,

Hugs.

Fabrício Guzzy.

Assunto: Re: [pfSense Support] RE: Using pfsense together with Microsoft IAS


Hi Markus,

it´s long time ago i wrote that tutorial, but maybe i could help you.

Could you verify some things ?

1. Are there any checked values except PAP in the "New remote Access Profile 
Policy Wizard / Edit Profile" Dialog Box ?

2. Is the User allowed to do Ras Dial-in (in the User Preferences) ?

3. Could you post some of the Eventlog Entries from the Windows Server and the 
Syslogs from pfsense ?

4. Are you using the Active Directory in Native 2003 Mode or in Mixed Mode with 
pre 2000 Domain Controllers ?

5. Do you have registered the IAS in Active Directory ?


Kind regards

Christian Veith
