Solution Check that: • The link between the NAS and the RADIUS server work well at both the physical and data link layers. • The IP address of the RADIUS server is correctly configured on the NAS. • The authentication and accounting UDP port numbers configured on the NAS are the same as those of the RADIUS server. • The RADIUS server's authentication and accounting port numbers are available. RADIUS accounting error Symptom A user is authenticated and authorized, but accounting for the user is not normal. Analysis The accounting server configuration on the NAS is not correct. Possible reasons include: • The accounting port number configured on the NAS is incorrect. • The accounting server IP address configured on the NAS is incorrect. For example, the NAS is configured to use a single server to provide authentication, authorization, and accounting services, but in fact the services are provided by different servers. Solution Check that: • The accounting port number is correctly configured. • The accounting server IP address is correctly configured on the NAS. Troubleshooting HWTACACS Similar to RADIUS troubleshooting. See "Troubleshooting RADIUS." Troubleshooting LDAP Symptom User authentication fails. Analysis Possible reasons include: • A communication failure exists between the NAS and the LDAP server. • The LDAP server IP address or port number configured on the NAS is not correct. • The username is not in the format userid@isp-name, or the ISP domain is not correctly configured on the NAS. • The user is not configured on the LDAP server. • The password entered by the user is incorrect. 57
