This optional attribute indicates the method with which the user’s declared identity was verified. There are three possible values for this attribute, which are listed in Table 4-2.

Table 4-2. Values for the Acct-Authentic attribute

Value	Authentication method
1	RADIUS
2	Local
3	Remote

The second value, “Local,” within the context of this attribute signifies that the client verified the identity of this user of its own accord through an authentication method other than RADIUS. This can cause problems when matching accounting data to authentication/authorization information, since no authorization data exists for the session.
