Hello colleagues,  
please help with the issue:

exactly as in manual (sorry can’t add an URL - this web site limitation)

1. /etc/influxdb.conf  
[http]  
https-enabled = true  
https-certificate = “/etc/ssl/influxdb-selfsigned.crt”  
https-private-key = “/etc/ssl/influxdb-selfsigned.key”

auth\_enable = true  
ping-auth-enabled = true

1. /etc/telegraf/telegraf.conf  
[[outputs.influxdb]]  
urls = [“:8086”]  
username = “monitoring”  
password = “monitoring”  
tls\_cert = “/etc/ssl/telegraf-selfsigned.crt”  
tls\_key = “/etc/ssl/telegraf-selfsigned.key”  
insecure\_skip\_verify = true  
[[inputs.influxdb]]  
urls = [  
“https::8086/debug/vars”  
]  
tls\_cert = “/etc/ssl/telegraf-selfsigned.crt”  
tls\_key = “/etc/ssl/telegraf-selfsigned.key”  
insecure\_skip\_verify = true

* * *

1. Console

influx -ssl -unsafeSsl -host localhost:8086  
~$ influx -ssl -unsafeSsl  
Connected to https::8086 version 1.7.9  
InfluxDB shell version: 1.7.9

> auth  
> username: admin  
> password:  
> show users  
> user admin

* * *

monitoring true  
admin true  
mmm false

> 

> SET PASSWORD FOR “monitoring” = ‘monitoring’  
> show grants for monitoring

well, the question is: how user “monitoring” with password ‘monitoring’ is unable to authorize if password was set a second before?

I think you just need to set `username` and `password` for the input as well as the output.

Hi Daniel,  
thank you. This must be “ **false** ”

/etc/influxdb/influxdb.conf  
Enables authentication on the /ping, /metrics, and deprecated /status  
Preformatted textendpoints. This setting has no effect if auth-enabled is set to false.  
**# ping-auth-enabled = false**
