Problem

I always forget the syntax for this, and I’ve been meaning to publish this for a while so here you go. If you have AAA setup and people can’t log in, then the ability to test authentication against a user’s username and password is a good troubleshooting step!

Usually I’m on a Cisco ASA but I’ll tag on the syntax for IOS as well.

Solution

Cisco ASA Test AAA Authentication From Command Line

You will need to know the server group and the server you are going to query, below the ASA is using LDAP, but the process is the same for RADIUS, Kerberos, TACACS+, etc.

Petes-ASA# show run | begin aaa
aaa-server TEST-LDAP-SERVER protocol ldap
aaa-server TEST-LDAP-SERVER (inside) host 192.168.110.10
 ldap-base-dn dc=TEST,dc=net
 ldap-scope subtree
 ldap-naming-attribute sAMAccountName
 ldap-login-password *****
 ldap-login-dn cn=asa,OU=Users,OU=Test-Corp,dc=TEST,dc=net
 server-type auto-detect

To test your user, (username: ttester password: Password123);

Petes-ASA# test aaa-server authentication TEST-LDAP-SERVER host 192.168.110.10 username ttester password Password123
INFO: Attempting Authentication test to IP address  (timeout: 12 seconds)
INFO: Authentication Successful

Cisco ASA Test AAA Authentication From ASDM

Log into the ADSM > Configuration > Device Management > Users/AAA > Select the Server Group > Select the Server > Test.

Select ‘Authentication’ > Enter Username/Password > OK.

Cisco IOS Test AAA Authentication From Command Line

As above, you need to know which server group, and server, you are going to test authentication against;

Petes-Router#show run aaa
!
aaa authentication login default local
aaa authorization exec default local
!
aaa group server radius RADIUS-GROUP
 server-private 192.168.110.10 key 666999
!
aaa new-model
aaa session-id common
!

Text

Petes-Router#test aaa group RADIUS-GROUP tester Password123 legacy
Attempting authentication test to server-group RADIUS-GROUP using radius
User was successfully authenticated.

OR

Petes-Router#test aaa group RADIUS-GROUP tester Password123 new-code
User successfully authenticated

USER ATTRIBUTES
