Authentication providers for TACACS+ and RADIUS

Does anyone supply WLS 8.1 authentication providers for TACACS+ and/or
RADIUS?
Ben

So in the ACS network config you add 2 NASes (or should that be NASi?)
One is of type TACACS+, enter the device ip and secret. The other is RADIUS - unless you need to use some vendor specific trickery you could stick with IETF RADIUS to keep it simple. Again enter the IP and the secret.
Assuming you a have at least 1 user in say, the default group (acs group 0) you then need to do some basic setup. In ACS a single group can have both RADIUS and TACACS+ config :-)
RADIUS will pretty much default to PPP anyway, but you should still set the Service-Type to Framed and set session timeouts etc.
With T+ you tick the boxes for the services that are allowed. For SSH login you might have to define a custom service first (under interface config)
Suggest you first take time to scan through the ACS docs.

Tacacs+ for exec and radius for ppp on the same ras

Hi, I'm going to implement tacacs+ for exec control and RADIUS for ppp control in a ras router, using the same ACS for tacacs+ and radius sessions.
Is there any problem with this kind of configuration ?
thank you in advance
Renato

Renato
I have recently done something very similar at a customer site. On a remote access server we configured it to use TACACS for exec control and to use Radius for ppp. In our case we are using different servers but I do not think that would be an issue. We also are generating aaa accounting records for the ppp sessions and sending the accounting records to the TACACS server. I have not had any particular problems with getting this to work.

Cisco ISE with TACACS+ and RADIUS both?

Hello,
I am initiating wired authentication on an existing network using Cisco ISE. I have been studying the requirements for this. I know I have to turn on RADIUS on the Cisco switches on the network. The switches on the network are already programmed for TACACS+. Does anybody know if they can both operate on the same network at the same time?
Bob

Hello Robert,
I believe NO, they both won't work together as both TACACS and Radius are different technologies.
It's just because that TACACS encrypts the whole message and Radius just the password, so I believe it won't work.
For your reference, I am sharing the link for the difference between TACACS and Radius.

Moreover, Please review the information as well.
Compare TACACS+ and RADIUS
These sections compare several features of TACACS+ and RADIUS.
UDP and TCP
RADIUS uses UDP while TACACS+ uses TCP. TCP offers several advantages over UDP. TCP offers a connection-oriented transport, while UDP offers best-effort delivery. RADIUS requires additional programmable variables such as re-transmit attempts and time-outs to compensate for best-effort transport, but it lacks the level of built-in support that a
TCP transport offers:
TCP usage provides a separate acknowledgment that a request has been received, within (approximately) a network round-trip time (RTT), regardless of how loaded and slow the backend authentication mechanism (a TCP acknowledgment) might be.
TCP provides immediate indication of a crashed, or not running, server by a reset (RST). You can determine when a server crashes and returns to service if you use long-lived TCP connections. UDP cannot tell the difference between a server that is down, a slow server, and a non-existent server.
Using TCP keepalives, server crashes can be detected out-of-band with actual requests. Connections to multiple servers can be maintained simultaneously, and you only need to send messages to the ones that are known to be up and running.
TCP is more scalable and adapts to growing, as well as congested, networks.
Packet Encryption
RADIUS encrypts only the password in the access-request packet, from the client to the server. The remainder of the packet is unencrypted. Other information, such as username, authorized services, and accounting, can be captured by a third party.
TACACS+ encrypts the entire body of the packet but leaves a standard TACACS+ header. Within the header is a field that indicates whether the body is encrypted or not. For debugging purposes, it is useful to have the body of the packets unencrypted. However, during normal operation, the body of the packet is fully encrypted for more secure communications.
Authentication and Authorization
RADIUS combines authentication and authorization. The access-accept packets sent by the RADIUS server to the client contain authorization information. This makes it difficult to decouple authentication and authorization.
TACACS+ uses the AAA architecture, which separates AAA. This allows separate authentication solutions that can still use TACACS+ for authorization and accounting. For example, with TACACS+, it is possible to use Kerberos authentication and TACACS+ authorization and accounting. After a NAS authenticates on a Kerberos server, it requests authorization information from a TACACS+ server without having to re-authenticate. The NAS informs the TACACS+ server that it has successfully authenticated on a Kerberos server, and the server then provides authorization information.
During a session, if additional authorization checking is needed, the access server checks with a TACACS+ server to determine if the user is granted permission to use a particular command. This provides greater control over the commands that can be executed on the access server while decoupling from the authentication mechanism.
Multiprotocol Support
RADIUS does not support these protocols:
AppleTalk Remote Access (ARA) protocol
NetBIOS Frame Protocol Control protocol
Novell Asynchronous Services Interface (NASI)
X.25 PAD connection
TACACS+ offers multiprotocol support.
Router Management
RADIUS does not allow users to control which commands can be executed on a router and which cannot. Therefore, RADIUS is not as useful for router management or as flexible for terminal services.
TACACS+ provides two methods to control the authorization of router commands on a per-user or per-group basis. The first method is to assign privilege levels to commands and have the router verify with the TACACS+ server whether or not the user is authorized at the specified privilege level. The second method is to explicitly specify in the TACACS+ server, on a per-user or per-group basis, the commands that are allowed.
Interoperability
Due to various interpretations of the RADIUS Request for Comments (RFCs), compliance with the RADIUS RFCs does not guarantee interoperability. Even though several vendors implement RADIUS clients, this does not mean they are interoperable. Cisco implements most RADIUS attributes and consistently adds more. If customers use only the standard RADIUS attributes in their servers, they can interoperate between several vendors as long as these vendors implement the same attributes. However, many vendors implement extensions that are proprietary attributes. If a customer uses one of these vendor-specific extended attributes, interoperability is not possible.
Traffic
Due to the previously cited differences between TACACS+ and RADIUS, the amount of traffic generated between the client and server differs. These examples illustrate the traffic between the client and server for TACACS+ and RADIUS when used for router management with authentication, exec authorization, command authorization (which RADIUS cannot do), exec accounting, and command accounting (which RADIUS cannot do).

OWSM 11g : Authentication Providers for X.509 and SAML policies

Hi All,
I am currently trying to implement the X.509 and SAML policies. As per the documentation for these polices I need to configure an authentication provider(or Identity Assertion provider) that can handle perimeter authentication via the NameCallback. I had configured an authentication provider(default authentication provider) that handled the namecallback and passwordcallback. What I can't figure out is how do these two authentication providers differs. And, incase one has to configure for the X.509 and SAML policies how to do the same.
Any pointers will be useful. Especially, from anyone who has worked and implemented the above policies.
Thanks in advance.

After research by Oracle Support it actually turns out that this problem was a combination of factors:
1) some clients were effectively using an invalid certificate so it is corrrect they got an error and everything worked fine when they started using the right certificate
2) it does, however, turn out that, in the case of an error the error handling has been obfuscated in WLS 10.3.6 as compared to WLS 10.3.4 which gives a more descriptive error stating the nature of the problem (missing certificate, invalid certificate, unknown user, ...). Apparently this was deemed a security issue and has thus been replaced by a generic "internal server error". It is however possible to re-activate this older behaviour using a couple of JAVA_OPTS that you pass during server startup:
-Dweblogic.wsee.security.debug=true -Dweblogic.wsee.security.verbose=true
The above reintroduced the behaviour we had in WLS 10.3.4 and thus solves our problem!

Configure PIX to use both TACACS and RADIUS for VPN

PIX 506E using ver 6.3: Whenever I add the command "crypto map mymap client authentication PARTNERAUTH" it removes the current TACACS+ client authentication. I need to have both until I've finished testing the radius server. Can I add an additional crypto map designation command to accomodate and use both the current TACACS+ (ACS) and RADIUS?

Hi,
Unfortunately what you want to do cannot be done on the pix, let's say that you have
multiple vpn groups on your firewall, as soon as you apply the following command:
crypto map mymap client authentication partnerauth
where parnerauth can a radius, tacacs, tacacs+ or an ACS server:
aaa-server partnerauth protocol radius
aaa-server partnerauth (inside) host 172.18.124.196 cisco123
As soon as you use "crypto map mymap client authentication partnerauth" the authentication
is applied globally on the crytpmap, thus affecting all the vpn groups configured.
You can have multiple vpn groups running on your firewall (dynamic crypto maps) but you
need to associate them to a static crypto map ( crypto dynamic-map dynmap 10 set
transform-set myset).
You can only have 1 crypto map applied to one interface, when you apply this line:
"crypto map mymap client authentication partnerauth"
The authentication is applied to ALL the clients, we cannot separate the extended
authentication based on the vpn group or ip address.
Please rate if that helps !

TACACS+ and RADIUS

Hi,
Can i configured on aironet 1100 RAIDIUS for users and TACACS for administration?
With Cisco ACS i can only add one option.
I want to centralize the AAA for all the equipments and use CISCO ACS!
But the AP's are radio clients already!
TKS

Yes, you can do both on the AP1100. Use something similar to the configuration below:
aaa new-model
aaa group server radius rad_eap
server x.x.x.x auth-port 1645 acct-port 1646
aaa group server tacacs+ tacacs_here
server x.x.x.x
aaa authentication login default group tacacs+ group tacacs_here
aaa authentication login wireless_client group rad_eap
dot11 ssid SSID4ME
vlan xxx
authentication open eap wireless_client

TACACS+ and RADIUS - Does either care about hostname?

When first experimenting with TACACS+, I remember changing the hostname on a router and having it cause issues with authentication. Is it normal for TACACS+ to use a devices hostname as part of the authentication process? What about RADIUS?

Hi,
Nope, neither one uses the hostname of the device for the AAA process.
Only take care of the source-interface (source IP address), the shared secret and the ports used.
HTH,
Tiago

Multiple authentication providers for the same identity store?

We are on WebLogic Server 11g PS5 and in the middle of configuring the authentication providers.
Turns out we an Active Directory instance where we have two distinct User Base DNs we would like to use, without overlap, but they share the Group Base DN.
What is the best practice to configure this? I think we could use the parent DN, but that would basically include the whole of the directory for users and groups, will that impact performance?

Hi Alexandre,
You might find this helpful - http://download.oracle.com/docs/cd/E10761_01/doc/oam.1014/b32420/v2authen.htm#BABJCHEJ. The text "suppose the user requests a resource that is protected by a form-based authentication scheme that redirects the user to a form with several options for logging in. When the user selects a login method on the form, he or she is again redirected, this time to a form containing a certificate-based authentication scheme." suggests that what you want to achieve is possible. If you do get this configured and working the way you want, can you please share with the forum?

Hi,
I have configured the aaa authentication for the PIX with tacacs protocol (ACS Server).
It works fine, now i would like to add the back up authentication, as follows:
- If the ACS goes down i can to be authenticated with the local database.
Is it possible with PIX, if yes how?

Hi,
I am trying to configure aaa using TACACS+ , i am not able to close.Problems are
1.It dosent ask for username /password in first level.
2.on second level it asks for user name it dosent authenticate the user .
Cud u pls let me know if the following config is correct.If not cud u help me .

ACS Solution Engine TACACS+ and Radius

I have an ACS Solutions Engine that is performing TACACS authentication for remote access to Switches and now want to add 802.1X support for port based access control against the ACS server also. For some reason this is not working for me at all. Does anyone have a document that will guide me in this.

There is a lot of reading on the topic. Maybe you could precise what is not working as expected ?
what EAP method are you doing ? how is your switchport configured ? Is there an error message on ACS ?

Bounding box for point and radius

I am using google maps and WGS 84 (4326).
I am trying to get the bounding box that contains a circle of a given radius in miles starting at a given lat/lon.

that works.

Authentication problem for SYSTEM and SYS users

Hi,
I am using form builder 6.0. I have developed a form without using a database table block. When trying to execute the form with user SYSTEM or SYS following errors occured:
1) does not authenticate and login screen prompts again and again but when I use user other than SYSTEM and SYS, I can successfully execute the form.
2) some times when trying to run form from Form builder error 'Service handle not initialized' is displayed.
anybody can help to resolve the following issues?
Regards

Muhammad,
two possibilities
1. You provide the wrong password
2. Connecting to SYS reaquires to connect as SYSDBA or SYSOPENER, which is not specified with the Forms logon dialog.

One WLC for Headquarter and Remote Site

Hi
I have a question about the WLC remote deployment.
We have the following design at the moment:
Headquarter
- Network 192.168.49.0 /24
- WLC 4402 Version 4.2.61.0
-- 3 x LAP1252
-- Layer 3 LWAPP
-- SSID wep
-- SSID wpa
- Windows PDC with Active Directory, DHCP Server and local Data Storage
- ACS Version 3.2 for TACACS and RADIUS authentication --> External DB to Active Directory
Remote Site
- Network 192.168.50.0 /24
- 2 x LAP1252
-- SSID wep
-- SSID wpa
- Windows PDC with Active Directory, DHCP Server and local Data Storage
- ACS Version 3.2 for TACACS and RADIUS authentication --> External DB to Active Directory
Connection between Headquarter and Remote Site
- 2 Mbit ADSL
The problem is, that the wireless clients on the remote site get an ip address out of the headquarter DHCP Range 192.168.49.0 /24. The users on the remote site
most of the time only use the local data server in the remote office. With the actual design the hole traffic is switched over the 2 Mbit ADSL connection the the
WLC in the headquarter and back to the remote site. That works but it is not that performant.
The problem could be solved with HREAP, but what I think is, that it is not possible to have the same SSID at headquarter and remote site with different VLANs.
How can I achieve, that the clients on the remote site connect to the same SSID (wep or wpa), get an ip address from the remote site DHCP server (192.168.50.0)
and the traffic is switched localy.
I hope you understand what the problem is.
Thanks in advance for your help!

Yes, putting the remote AP's in HREAP mode will allow the same WLANs to be available on the AP's but the traffic would be locally switched at the AP instead of being tunneled back to the controller. After you put the AP in HREAP mode you then would configure which VLAN you want traffic for each WLAN to be dumped onto for that AP.
