Troubleshooting do Proxy de Autenticação
Contents
Introduction
Este documento define e demonstra os mecanismos de solução de problemas disponíveis no Cisco IOS® para solucionar problemas relacionados ao Proxy de Autenticação (Auth-Proxy). Este documento define os comandos debug e show e, em seguida, ilustra exemplos dessas depurações e comandos.

Comandos debug e clear
Antes de tentar qualquer comando debug, consulte Informações importantes sobre comandos debug.
-
debug tacacs | radius - Exibe informações associadas ao TACACS ou RADIUS.
-
debug aaa authentication - Exibe informações sobre a autenticação AAA/TACACS+. Usado para ver quais métodos de autenticação estão sendo usados e quais são os resultados desses métodos.
-
debug aaa authorization - Exibe informações sobre a autorização AAA/TACACS+. Utilizado para verificar os métodos de autorização utilizados e os resultados desses métodos.
Se necessário, use estes comandos:
-
debug ip auth-proxy {function - trace} - Exibe as funções de proxy de autenticação.
-
debug ip auth-proxy {http} - Exibe eventos HTTP relacionados ao proxy de autenticação.
Para limpar entre sessões, use este comando:
-
limpar cache auth-proxy de ip {* | host ip address} - Limpa todas as entradas de proxy de autenticação, incluindo perfis de usuário e listas de controle de acesso dinâmicas (ACLs). Se o endereço IP for especificado, ele limpará a entrada de proxy de autenticação para o host especificado.
O comando show ip access-lists - externo
Antes de o comando access-list ser passado:
sec-3640#show ip access-lists
Extended IP access list 116
permit tcp host 10.31.1.47 host 10.31.1.150 eq www
deny tcp host 10.31.1.47 any (16 matches)
deny udp host 10.31.1.47 any (26 matches)
deny icmp host 10.31.1.47 any
permit tcp 10.31.1.0 0.0.0.255 any (53 matches)

permit tcp 171.68.118.0 0.0.0.255 any (242 matches)
permit udp 171.68.118.0 0.0.0.255 any
Após o comando access-list ser transmitido:

O usuário vê “Falha na autenticação!”
O usuário do TACACS digita o nome de usuário e a senha corretos, mas a autorização falha
Debug exibe:
02:17:01: TAC+: ver=192 id=945629484 received AUTHEN status = PASS 02:17:02: TAC+: (1368282367): received author response status = FAIL 02:17:02: TAC+: Closing TCP/IP 0x61CAFFC8 connection to 171.68.118.115/49 02:17:02: AAA/AUTHOR (1368282367): Post authorization status = FAIL
O usuário vê “Falha na autenticação!”
O usuário de RADIUS digita o nome de usuário e a senha corretos, mas o ACL retorna em formato inválido
A depuração mostra a(s) ACL(s) desativada(s), mas não aplicada(s) e o usuário não pode passar pelo firewall.
O usuário vê "Authentication Successful!"
Usuário TACACS insere o nome de usuário e senha corretos, mas o ACL retorna no formato inválido
A depuração não parece ser diferente daquela realizada na autenticação bem-sucedida, mas os ACLs não são aplicados e o usuário não pode passar pelo firewall.
O usuário vê "Authentication Successful!"
O usuário RADIUS digita o nome de usuário e a senha corretos, mas Priv-Ivl 15 não é retornado
Debug exibe:
02:00:54: RADIUS: saved authorization data for user 61CA670C at 61C5585C 02:00:54: AAA/AUTHEN (706562375): status = PASS 02:00:54: AAA/AUTHOR/HTTP (4224202114): Port='' list='default' service=AUTH-PROXY 02:00:54: AAA/AUTHOR/HTTP: (4224202114) user='baduser' 02:00:54: AAA/AUTHOR/HTTP (4224202114): send AV service=auth-proxy 02:00:54: AAA/AUTHOR/HTTP (4224202114): send AV cmd* 02:00:54: AAA/AUTHOR/HTTP (4224202114): found list "default" 02:00:54: AAA/AUTHOR/HTTP (4224202114): Method=RTP (radius) 02:00:54: RADIUS: cisco AVPair "auth-proxy:priv-lvl=1"
O usuário vê "Falha de Autenticação", embora a depuração do roteador não indique nada de anormal, exceto o nível de privilégio errado. As ACLs não são aplicadas.
O usuário de TACACS introduziu nome de usuário e senha corretos, mas Priv-lvl 15 não foi retornado
A depuração não parece diferente do que após a autenticação com êxito.
O usuário verá "Falha de Autenticação!"
