After installing RSA Authentication Manager in accordance with the RSA documentation, create an agent host record to configure the RSA Authentication Manager to accept connections from Forefront TMG for user authentication. The name must resolve to an IP address on the local RSA Authentication Manager network. If required, in the Network address box, type the IP address of the computer running Forefront TMG. In the Agent type list, click Net OS Agent. If you want all users to be able to authenticate, select Open to All Locally Known Users. In Agent Host, click Generate Configuration Files. Click One Agent Host, click OK, double- click the name of the computer running Forefront TMG, and then save the Sdconf. Forefront TMG. Note. By default, the Sdconf. ACE\Data folder on the RSA Authentication Manager computer. On the computer running Forefront TMG, check that the local Network Service account has read/write access for the following registry key: HKLM\Software\SDTI\ACECLIENTThis ensures that Forefront TMG is able to write the secret to the registry. On the computer running Forefront TMG, configure the Network Service account with read permissions for the Sdconfig. If the computer running Forefront TMG is configured with multiple network adapters, you should explicitly configure the network adapter address through which Forefront TMG connects to the RSA Authentication Manager for authentication. To do this, specify the IP address as a string value in the following registry key: HKEY. You can test Secur. ID authentication using the RSA Test Authentication Utility. For more information about the tool, see Microsoft. This tool checks connectivity between the computer running Forefront TMG and the server running RSA Authentication Manager. The tool can also obtain the secret required for encrypting communications between the servers. RADIUS - Wikipedia, the free encyclopedia. Remote Authentication Dial- In User Service (RADIUS) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA or Triple A) management for users who connect and use a network service. RADIUS was developed by Livingston Enterprises, Inc. These networks may incorporate modems, DSL, access points, VPNs, network ports, web servers, etc. Network access servers, the gateways that control access to a network, usually contain a RADIUS client component that communicates with the RADIUS server. AAA stands for authentication, authorization and accounting. Authentication and authorization characteristics in RADIUS are described in RFC 2. RFC 2. 86. 6. Authentication and authorization. The credentials are passed to the NAS device via the link- layer protocol - for example, Point- to- Point Protocol (PPP) in the case of many dialup or DSL providers or posted in an HTTPS secure web form. In turn, the NAS sends a RADIUS Access Request message to the RADIUS server, requesting authorization to grant access via the RADIUS protocol. Additionally, the request may contain other information which the NAS knows about the user, such as its network address or phone number, and information regarding the user's physical point of attachment to the NAS. The RADIUS server checks that the information is correct using authentication schemes such as PAP, CHAP or EAP. The user's proof of identification is verified, along with, optionally, other information related to the request, such as the user's network address or phone number, account status, and specific network service access privileges. Historically, RADIUS servers checked the user's information against a locally stored flat file database. Modern RADIUS servers can do this, or can refer to external sources . Reasons may include failure to provide proof of identification or an unknown or inactive user account. Access Challenge - Requests additional information from the user such as a secondary password, PIN, token, or card. Access Challenge is also used in more complex authentication dialogs where a secure tunnel is established between the user machine and the Radius Server in a way that the access credentials are hidden from the NAS. Access Accept - The user is granted access. Once the user is authenticated, the RADIUS server will often check that the user is authorized to use the network service requested. A given user may be allowed to use a company's wireless network, but not its VPN service, for example. Again, this information may be stored locally on the RADIUS server, or may be looked up in an external source such as LDAP or Active Directory. Each of these three RADIUS responses may include a Reply- Message attribute which may give a reason for the rejection, the prompt for the challenge, or a welcome message for the accept. The text in the attribute can be passed on to the user in a return web page. Authorization attributes are conveyed to the NAS stipulating terms of access to be granted. For example, the following authorization attributes may be included in an Access- Accept: The specific IP address to be assigned to the user. The address pool from which the user's IP should be chosen. The maximum length of time that the user may remain connected. An access list, priority queue or other restrictions on a user's access. L2. TP parameters. VLAN parameters. Quality of Service (Qo. S) parameters. When a client is configured to use RADIUS, any user of the client presents authentication information to the client. This might be with a customizable login prompt, where the user is expected to enter their username and password. Alternatively, the user might use a link framing protocol such as the Point- to- Point Protocol (PPP), which has authentication packets which carry this information. Once the client has obtained such information, it may choose to authenticate using RADIUS. To do so, the client creates an . When a password is present, it is hidden using a method based on the RSA Message Digest Algorithm MD5. Accounting. This is known as postfix notation for the realm. Another common usage is prefix notation, which involves prepending the realm to the username and using '\' as a delimiter. Modern RADIUS servers allow any character to be used as a realm delimiter, although in practice '@' and '\' are usually used. Realms can also be compounded using both prefix and postfix notation, to allow for complicated roaming scenarios; for example, somedomain. Although realms often resemble domains, it is important to note that realms are in fact arbitrary text and need not contain real domain names. Realm formats are standardized in RFC 4. Network Access Identifier (NAI) in the form of 'user@realm'. In that specification, the 'realm' portion is required to be a domain name. However, this practice is not always followed. If the realm is known, the server will then proxy the request to the configured home server for that domain. The behavior of the proxying server regarding the removal of the realm from the request (. In addition, the proxying server can be configured to add, remove or rewrite AAA requests when they are proxied over time again. Proxy Chaining is possible in RADIUS and authentication/authorization and accounting packets are usually routed between a NAS Device and a Home server through a series of proxies. Some of advantages of using Proxy chains include scalability improvements, policy implementations and capability adjustments. But in roaming scenarios, the NAS, Proxies and Home Server could be typically managed by different administrative entities. Hence, the trust factor among the proxies gains more significance under such Inter- domain applications. Further, the absence of end to end security in RADIUS adds to the criticality of trust among the Proxies involved. Proxy Chains are explained in RFC 2. Security. More generally, some roaming partners establish a secure tunnel between the RADIUS servers to ensure that users' credentials cannot be intercepted while being proxied across the internet. This is a concern as the MD5 hash built into RADIUS is considered insecure. The fields are transmitted from left to right, starting with the code, the identifier, the length, the authenticator and the attributes. RADIUS Codes (decimal) are assigned as follows: Code. Assignment. 1Access- Request. Access- Accept. 3Access- Reject. Accounting- Request. Accounting- Response. Access- Challenge. Status- Server (experimental)1. Status- Client (experimental)2. Reserved. The Identifier field aids in matching requests and replies. The Length field indicates the length of the entire RADIUS packet including the Code, Identifier, Length, Authenticator and optional Attribute fields. The Authenticator is used to authenticate the reply from the RADIUS server, and is used in encrypting passwords; its length is 1. Attribute value pairs. The length of the radius packet is used to determine the end of the AVPs. AVP Type. Assignment. User- Name. 2User- Password. CHAP- Password. 4NAS- IP- Address. NAS- Port. 6Service- Type.
