Chapter 7 Configuring AAA Rules for Network Access

Configuring Authentication for Network Access

The following example shows a typical cut-through proxy configuration to allow a user to log in through the ASA. In this example, the following conditions apply:

•The ASA IP address is 192.168.123.10.

•The Active Directory domain controller has the IP address 10.1.2.10.

•The end user client has the IP address 192.168.123.10 and uses HTTPS to log in through a web portal.

•The user is authenticated by the Active Directory domain controller via LDAP.

•The ASA uses the inside interface to connect to the Active Directory domain controller on the corporate network.

hostname(config)# access-list AUTH

extended permit tcp any 192.168.123.10 255.255.255.0 eq http

hostname(config)# access-list AUTH

extended permit tcp any 192.168.123.10 255.255.255.0 eq https

hostname(config)# auth-prompt prompt Enter Your Authentication hostname(config)# auth-prompt accept You are Good hostname(config)# auth-prompt reject Goodbye

In this example, the following guidelines apply:

•In access-listcommands, you should configure permit user NONE rules before entering the access-list 100 ex deny any any command to allow unauthenticated incoming users to trigger AAA cut-through proxy.

•In access-list AUTH commands, permit user NONE rules specify that only unauthenticated users can trigger AAA cut-through proxy.

hostname(config)# access-list listenerAuth extended permit tcp any any hostname(config)# aaa authentication match listenerAuth inside ldap hostname(config)# aaa authentication listener http inside port 8888 hostname(config)# access-list 100 ex permit ip user SAMPLE\user1 any any hostname(config)# access-list 100 ex deny ip user SAMPLE\user2 any any hostname(config)# access-list 100 ex permit ip user NONE any any hostname(config)# access-list 100 ex deny any any

hostname(config)# access-group 100 in interface inside hostname(config)# aaa authenticate match 100 inside user-identity

The following example shows how you can use AAA rules plus identity firewall (cut-through proxy) to authenticate successfully:

hostname(config)# access-list 100 ex permit ip user CISCO\xyz any any hostname(config)# access-list 100 ex deny ip user CISCO\abc any any hostname(config)# access-list 100 ex permit ip user NONE any any hostname(config)# access-list 100 ex deny any any hostname(config)# access-group 100 in interface inside hostname(config)# access-list 200 ex permit user NONE any any hostname(config)# aaa authenticate match 200 inside user-identity
