    Example: Associating Multiple Domain Names with a Specific Domain Name

    In this example, an administrator wants to use aliases; that is, to associate multiple domain names with a specific domain name and not allow other domain names.

    1. Create an AAA profile.
      host1(config)#aaa profile toAbc
    2. Map the original domain name to the mapped domain name for domain map lookup.
      host1(config-aaa-profile)#translate abc1.com abc.com host1(config-aaa-profile)#translate abc2.com abc.com host1(config-aaa-profile)#translate abc3.com abc.com
    3. Specify the domain name you want to restrict.
      host1(config-aaa-profile)#deny default
    4. Associate the AAA profile with the designated PPP interface.
      host1(config-if)#ppp aaa-profile toAbc

    When configured as such, the following scenario is typical:

    • PPP passes the AAA profile toAbc to AAA in the authentication request.
    • AAA:
      • Receives the authentication request from PPP with the subscriber’s name jane@abc1.com
      • Parses the domain name abc1.com and examines the specified AAA profile toAbc
      • Determines that the AAA profile toAbc is valid
      • Searches toAbc for a match on the PPP subscriber’s domain name and finds a match
      • Continues as normal using the domain name abc.com

        Note: If there is no matching entry in the AAA profile for the user’s domain name or for the domain name default, then AAA continues processing as if there were no AAA profile.

        If the user’s name does not contain a domain name, then AAA attempts to match to the domain name none in the AAA profile. If there is no entry for none, then AAA attempts to match for the domain name default in the AAA profile. If there is no entry for either none or default, then AAA continues processing as if there were no AAA profile.
