SBR for RADIUS Authentication

Hi Everyone,
Does anybody know if Steel Belt Radius would be able to authenticate both the telnet and enable passwords for RADIUS authentication?
I have tried IAS, but apparently IAS does not have any understanding of the enable password and therefore returns an error.
Any help would be great.
Thanks,
Dan

"enable password" authorization is not supported in RADIUS authorization. TACACS+ supports it.

Shell access required for RADIUS authentication?

Hello all,
A customer of mine has a fleet of modern Mac laptops, all accessing 3 AFP file servers. Access to those file servers is governed by a Snow Leopard Open Directory Master. Pretty simple.
I’ve been tasked with introducing RADIUS authentication to the WLAN there. The WAPs are all Airport Extremes, so again the setup is pretty simple.
But in testing, I see that users can authenticate to the RADIUS WLAN only if I give those user accounts shell access in Open Directory. If a user’s account has a login shell set to None (our previous default), then any RADIUS authentication attempt produces the following log error:
Auth: [unix] [USERNAME]: invalid shell [/dev/null]
If I switch that user’s login shell to (for example) /bin/bash, then restart RADIUS, that user authenticates successfully thereafter.
Is this expected behavior? Is there an alternative to giving everyone shell access?
Thanks for any info,

NMAS based token for radius authentication towards checkpoint firewall

hi,
i'm looking for token based access towards a checkpoint firewall. i found
out about radius, and think that's the way to go.
our user administration is NW65SP2 & Edir 8.7.3 based.
has anyone a success story about a token based radius server based on this
configuration ?
which token ?
additional software ?
anyone ?

Radius authentication for the browser-based webtop

Hiya all,
With help of the radius-authentication module for apache (http://www.freeradius.org/mod_auth_radius/) and web-authentication it is possible to use radius-authentication for the classic-webtop. Has anyone got Radius authentication working for the browser-basedwebtop?
SSGD version:
Sun Secure Global Desktop Software for Intel Solaris 10+ (4.30.915)
Architecture code: i3so0510
This host: SunOS sgd1.<removed> 5.10 Generic_118855-36 i86pc i386 i86pc
I have the radius-module running for authentication of a single directory with the apache-config-lines:
SetEnvIf Request_URI "\.(cab|jar|gif|der)$" sgd_noauth_ok
<LocationMatch "/secure">
Order Allow,Deny
Allow from env=sgd_noauth_ok
AuthName "Radius authentication for SGD"
Authtype Basic
AuthRadiusAuthoritative on
AuthRadiusCookieValid 540
AuthRadiusActive On
Require valid-user
Satisfy any
</LocationMatch>
When changing the line <LocationMatch "/secure"> to <LocationMatch "/sgd"> the browser asks for a authentication and then a 'Not Found' page is being displayed.
When using the config-lines from http://docs.sun.com/source/819-6255/webauth_config_browser.html the login-page is being displayed normally and SSGD works.
The main difference I can find between the location /secure and /sgd is: /secure is a simple directory and /sgd is a JkMount to Tomcat.
Changing the JkLogLevel to debug gives the following info in the JkLogFile:

Any help will be usefull since I am allready stuck on this problem for a couple of days :(
Thanks,

I got response from the Fat Bloke on the mailing list.
Adding the following line in the apache httpd.conf seams to help and resolved my problem:
Alias /sgd "/opt/tarantella/webserver/tomcat/5.0.28_axis1.2final_jk1.2.8/webapps/sgd"
Thanks The Fat Bloke !!

These instructions are for a 4.2 SGD installation using SGD's third
party web authentication with mod_auth_radius.so (www.freeradius.org).
With 4.2 Sun didn't distribute enough of the Apache configured tree
to enable the use of axps to build the mod_auth_radius module, 4.3 is
better - Sun now install a modified axps and include files, I haven't
tried this with 4.3 yet though.
I built the mod_auth_radius module for Apache 1.3.33 (shipped with 4.2)
So, this is how we got this working with Radius (tested with SBR
server and freeradius.org server.)
Install SGD in the usual way.
Enable 3rd party authentication:
According to:
http://docs.sun.com/source/819-4309-10/en-us/base/standard/
webauth_config_browser.html
Configure the Tomcat component of the Secure Global Desktop Web
Server to
trust the web server authentication. On each array member, edit the
/opt/tarantella/webserver/tomcat/version/conf/server.xml file. Add the
following attribute to the connector element (<Connector>) for the
Coyote/JK2 AJP 1.3 Connector:
tomcatAuthentication="false"
# cat /opt/tarantella/webserver/tomcat/5.0.28_axis1.2final_jk1.2.8/
conf/server.xml

<Connector port="8009" minProcessors="5" maxProcessors="75"
tomcatAuthentication="false"
enableLookups="true" redirectPort="8443"
acceptCount="10" debug="0" connectionTimeout="0"
useURIValidationHack="false"
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>
"By default, for security reasons, Secure Global Desktop
Administrators can't
log in to the browser-based webtop with web server authentication.
The standard
login page always displays for these users even if they have been
authenticated
by the web server. To change this behavior, run the following command:"
# tarantella config edit --tarantella-config-login-thirdparty-
allowadmins 1
Without this, after authenticating via webauth, the user will be
prompted for a
second username and password combination.

RADIUS Authentication for Enable PW

Hi Everyone,
I have my RADIUS authentication working for login passwords but not for the enable password. My config is below;
aaa new-model
aaa authentication login default group radius local
aaa accounting network default start-stop group radius
When I add the command;
aaa authentication enable default group radius enable
I would expect it to allow me to enter my RADIUS pw for the enable one to, but it doesnt. Nor does it allow me to enter the locally configured one?
Any help would be great,
Thanks,
Dan

Radius authentication for wifi users

Hi all,
I have a aeronet 1250 access point and i have a windows 2003 radius server configured to authenticate users.
I need to configure the access point for radius authentication .
Can anyone please help me to configure the access point .
thanks in advance ,

Radius authentication for privileged access

Hello,
          I have configured Cisco 6513 for radius authentication with following commands.
aaa new-model
aaa authentication login authradius group radius line
aaa accounting exec acctradius start-stop group radius
radius-server host <radius-ip> auth-port 1812 acct-port 1646 key 6912911
line vty 0 4
accounting exec acctradius
login authentication authradius
     This is working pretty fine. I want to configure radius authentication for priviledged access / for enable access.
     I am using TeKRadius as Radius server.
     Please help.
Thanks and Regards,
Pratik

Hi Pratik
Sorry I mostly use only TACACS+ for AAA as it provides better granularity of access controls.
You'll need to make some specific changes to your RADIUS config so that nominated users ( the ones you want to be able to go to enable mode ) get put straight into enable mode upon login.
There's a guide here http://www.blindhog.net/cisco-aaa-login-authentication-with-radius-ms-ias/ which details the steps if you're using the Microsoft IAS radius server - you should be able to figure out that changes you need to make to your own server from there.

Radius authentication with ISE - wrong IP address

Hello,
We are using ISE for radius authentication. I have setup a new Cisco switch stack at one of our locations and setup the network device in ISE. Unfortunately, when trying to authenticate, the ISE logs show a failure of "Could not locate Network Device or AAA Client" The reason for this failure is the log shows it's coming from the wrong IP address. The IP address of the switch is 10.xxx.aaa.241, but the logs show it is 10.xxx.aaa.243. I have removed and re-added the radius configs on both ISE and the switch, but it still comes in as .243. There is another switch stack at that location (same model, IOS etc), that works properly.
The radius config on the switch:
aaa new-model
aaa authentication login default local
aaa authentication login Comm group radius local
aaa authentication enable default enable
aaa authorization exec default group radius if-authenticated
ip radius source-interface Vlanyy
radius server 10.xxx.yyy.zzz
address ipv4 10.xxx.yyy.zzz auth-port 1812 acct-port 1813
key 7 abcdefg
The log from ISE:

As a test, I setup a device using the .243 address. While ISE claims it authenticates, it really doesn't. I have to use my local account to access the device.
Any advice on how to resolve this issue would be appreciated. Please let me know if more information is needed.

Well from the debug I would say there may be an issue with the addressing of the radius server on the switch.
radius-server host 10.xxx.xxx.xxx key******** <--- Make sure this address and Key matches what you have in ISE PSN and that switch. Watch for spaces in your key at the begining or end of the string.
What interface should your switch be sending the radius request?
ip radius source-interface VlanXXX vrf default
Here is what my debug looks like when it is working correctly.

This is a default template I use for all my devices routers or switches hope it helps. I have two PSN's that is why we have two radius-server host commands..
aaa authentication login vty group radius local enable
aaa authentication login con group radius local enable
aaa authentication dot1x default group radius
aaa authorization network default group radius
aaa accounting system default start-stop group radius
ip radius source-interface VlanXXX vrf default
radius-server attribute 6 on-for-login-auth
radius-server attribute 6 support-multiple
radius-server attribute 8 include-in-access-req
radius-server attribute 25 access-request include
radius-server dead-criteria time 30 tries 3
radius-server host xxx.xxx.xxx.xxx auth-port 1645 acct-port 1646 key *********
radius-server host xxx.xxx.xxx.xxx auth-port 1645 acct-port 1646 key *********
radius-server vsa send accounting
radius-server vsa send authentication
You can use this in the switch to test radius
test aaa group radius server 10.xxx.xxx.xxx <username> <password>

RADIUS authentication on IAS server

I have a 1200 AP configured for RADIUS authentication on Microsoft IAS server but I am experiencing a problem getting clients authenticated. (Association is working fine.)
The 1200 is connected to the IAS Server via an 837 router (no switch involved) and I am wondering if any RADIUS settings have to be configured on the 837 for AAA communication to pass through to the IAS server or will the requests pass through automatically?

ScottMac is correct, if you're using IAS you need to use PEAP which requires a security cert. Microsoft provide a very nice toolkit of scripts and documents to simplify the installation and configuration of IAS, Cert Services, etc, etc, you can get it from here:

How to configure number of RADIUS authentication attempts

Hello,
I'm looking for a way to configure the number of RADIUS authentication attempts on a Server 2012.
The server has RRAS but uses an external server for RADIUS authentication. By default, the RRAS (RADIUS client) sever sends
3 RADIUS Access-Request messages if there is no reponse from the RADIUS server. I would like to configure that to only
1 authentication retry.
I have tried to configure settings in the registry, but it did not help. I have configured:
HKLM\SYSTEM\CurrentControlSet\Services\RemoteAccess\Authentication\Providers\{1AA7F83F-C7F5-11D0-A376-00C04FC9DA04}\Servers\radiusserver1 - the DWORD value
Retries. Also, I have configured: HKLM\SYSTEM\CurrentControlSet\Services\RemoteAccess\Parameters - with a DWORD value
AuthenticateRetries. Nothing worked.
Is there a way to configure the number of RADIUS authentication attempts? Advice appreciated.

Hi,
According to your description, my understanding is that you want to change the retry times of RADIUS client.
I set up a test environment according to your description:
1. Windows 7 as the VPN client.
2. Windows Server 2012 as VPN server, also install NPS as RADIUS client and forward request to RADIUS Server.
3. Windows Server 2008 R2 as the RADIUS Server.
I have tried to reduce the time of dropping the request, and some registry entry, but all have no effect on 3 times retry of RADIUS access request. From now I haven’t found any Microsoft official instruction about this. I am wondering the reason you
want to change this.
Best Regards,
Eve Wang

Cisco ACS for Unix authentication

My company is looking for a single sign on for all the windows and unix servers mainly for admins. I was wondering if Cisco ACS will work for this.
Basically the authentication will be all for the servers and routers ofcourse. I am thinking if I specifies windows AD in ACS config, Can I get the unix boxes to get authenticated against Radius?
Any help will be appreciated.
Manny

Hi,
Authentication of unix servers via ACS over radius protocol can be achiveable,check out the below link client end configuration needs to be done for radius authentication
Hope that helps out your query !!

VPN3k Radius authentication Error

I dont know what i am doing wrong, but everytime i try to setup a VPN3k for radius authentication get the following error:
An error has occurred while attempting to perform the operation.
Authentication Error: No active server found
The server is correctly configured on the vpn3k and also i setup the vpn3k as a client to ACS. The radius server works fine with any other routers.
Can anybody please share some tips.
Thanks

I can suggest several things to check about this issue. Are you sure that you have correct IP connectivity between the devices? (check this by pinging from the vpn3k to the server and ping from the server to the vpn3k) Are you sure that you have configured the correct key for cummunication from the vpn3k to the server? Does the server see any connection attempt from the vpn3k? (check logs and failed attempt reports on the server) Is there any access list on any router along the path from the vpn3k to the server which might be denying the request or the response?

Can not do radius authentication via WLC 4400... Please help!

Hey,
I am configuring an old WLC4400 with V4.2.130.0. I added a new sub-interface for VLAN 50 with proper IP for the subnet and then add the Radius server(Windows server 2008 with NPS) onto WLC4400. I then created new WLAN with WPA+WPA2 Encryption and 802.1x key management and selected the Radius server under AAA for authentication.
Configured the test XP with WPA-Enterprise and PEAP as EAP method. I purposely configured computer to prompt for username and password.
When I try to connect, I did get prompt for username and password. However after that nothing happens. It seems like laptop just keep trying to authenticate.
I checked windows event log and do not see anything under NPS. I know this windows server NPS setup works as it is also the authentication server for our remotevpn.
So my question: is there any special option I need to turn on for WLC in order for Radius authentication work? Or is there any known bug with V4.2.130 (I searched bug toolkit but did not see anything).
Any suggestion is appeciated!
Thanks,
/S

Configuration
Open Network Connections by clicking on the Windows Start button, right-clicking on My Network Places, Properties, or Start > Control Panel then double-click on Network Connections.
Right-click on your wireless network adaptor and choose Properties.
Note: If your wireless connection is part of a Network Bridge you must remove it from the Bridge before continuing.
Click on the Wireless Networks tab at the top of this dialog box.
In the Preferred Networks section click Add...
Enter "Imperial-WPA" as the Network Name (ssid). Note: this is case-sensitive.
Either select WPA2 for Network Authentication: and AES for Data Encryption:
or select WPA for Network Authentication: and TKIP for Data Encryption:
(WPA2 + AES is more secure)
Check that the This is a computer-to-computer (adhoc) network check-box is not ticked.
Then click on the Authentication tab at the top of this dialog-box.
For EAP type: select Protected EAP (PEAP).
Check that the Authenticate as computer... and Authenticate as guest... check boxes are not checked.
Then click on the Properties button.
Then click on Configure...
Un-tick the Automatically use my Windows logon name... check box.
Click OK, then click OK on the previous two dialog boxes to exit.
First connection
Once you are within range of the wireless network a balloon should appear on the task bar prompting you for credentials.
Click on this balloon and you will be prompted for your logon credentials
Enter your college username, password and "IC" for the Logon domain. Then click on OK.
You should also be prompted to accept the server certificate.
Note: If you change your college password at any time you will be prompted to enter your new password when you next connect to the network.
Thanks,
Scott

RADIUS Authentication for Guest users

Hi,
I currently use a 4402 WLC located in our DMZ to authenticate Guest users - local authentication is in place. I would not like to setup RADIUS authentication via a Cisco NAC server. In order not to affect current guest users, I created a new WLAN and configured with RADIUS server details under WLANs->Edit->Security. I can associate to new WLAN and obtain a DHCP address no problem, but when I browse to an external website, I do not get prompted for authentication from the RADIUS server. I don't see any auth requests hitting our firewal, so am assuming the problem is with the WLC config.
Can anyone provide any details of what config is required?
Security Policy - Web-Auth
Security-> L2 - None
Security-> L3 - Authentication
Security-> AAA Servers - Auth and Acc server set
Many thanks
Liam

your setup sounds pretty okay. have you got local user accounts set up on the WLC for the test WLAN? if you do, check to see that the priority order for web authentication for the test WLAN prefers the AAA account. you will have to do it directly on your controller as i do not think you have that option in WCS.
hope that helps

NAC guest server with RADIUS authentication for guests issue.

Hi all,
We have just finally successfully installed our Cisco NAC guest server. We have version 2 of the server and basically the topology consists of a wism at the core of the network and a 4402 controller at the dmz, then out the firewall, no issues with that. We do however have a few problems, how can we provide access through a proxy without using pak files obviously, and is there a way to specify different proxies for different guest traffic, based on IP or a radius attribute etc.
The second problem is more serious; refer to the documentation below from the configuration guide for guest nac server v2. It states that hotspots can be used and the Authentication option would allow radius authentication for guests, I’ve been told otherwise by Cisco and they say it can’t be done, has anyone got radius authentication working for guests.
https://www.cisco.com/en/US/docs/security/nac/guestserver/configuration_guide/20/g_hotspots.html

Step 7 From the Operation mode dropdown menu, you can select one of the following methods of operation:
•Payment Provider—This option allows your page to integrate with a payment providing billing system. You need to select a predefined Payment Provider from the dropdown. (Refer to Configuring Payment Providers for details.) Select the relevant payment provider and proceed to Step 8.
•Self Service—This option allows guest self service. After selection proceed to Step 8.
•Authentication—This option allows RADIUS authentication for guests. Proceed to Step 9.
----- END QUOTE-----
Your help is much appreciated on this, I’ve been looking forward to this project for a long time and it’s a bit of an anti climax that I can’t authenticate guests with radius (We use ACS and I was hoping to hook radius into an ODBC database we have setup called open galaxy)
Regards
Kevin Woodhouse

Well I will try to answer your 2nd questions.... will it work... yes. It is like any other radius server (high end:)) But why would you do this for guest.... there is no reason to open up a port on your FW and to add guest accounts to and worse... add them in AD. Your guest anchor can supply a web-auth, is able to have a lobby admin account to create guest acounts and if you look at it, it leaves everything in the DMZ.
Now if you are looking at the self service.... what does that really give you.... you won't be able to controll who gets on, people will use bogus info and last but not least.... I have never gotten that to work right. Had the BU send me codes that never worked, but again... that was like a year ago and maybe they fixed that. That is my opinion.
