Scenario: A NetScaler Engineer has created a local account for a user according to the below

configuration:

add system user NSUser userpassword -timeout 900

add system group "NetScaler users" -timeout 900

add system cmdPolicy netscaler-users ALLOW

"(^man.*)|(^show\\s+(?!system)(?!configstatus)(?!ns ns\\.conf)(?!ns savedconfig)(?!ns runningConfig)(?

!gslb runningConfig)(?!audit messages)(?!techsupport).*)|(^stat.*)"

bind system group "NetScaler users" -userName NSUser

bind system group "NetScaler users" -policyName netscaler-users 100

The user is able to log on but is NOT able to execute certain commands. The engineer goes back and

looks at the logs, and the following is displayed:

Oct 6 13:34:15 192.168.10.50 10/06/2014:13:34:15 GMT ns1 0-PPE-0 : CLI

CMD_EXECUTED 4303 0 : User NSUser - Remote_ip 192.168.10.10 - Command "show ns

runningConfig" - Status "ERROR: Not authorized to execute this command"

Why is the command NOT working for the user?

A. cmdPolicy is NOT configured to allow the command
