How to incorporate username and password for the MQTT broker authentcation in mqtt sample

Question

I am using samples/net/mqtt for MQTT connection. I have a custom MQTT broker with SSL/TLS encryption which also requires username and password for authentication. I am confused as to where to add this. 
 I am using actnius icarus ns 
 sdk 2.3.0

Hi, 
 You can set the username in the struct mqtt_helper_conn_params conn_params in connect_work_fn in transport.c. 
 However, the mqtt_helper library does not support setting a password. So you will have to add that to the mqtt_helper_conn_params struct and client_connect function in the mqtt_helper library. 
 Best regards, 
 Didrik

 Yes, you will need to add password handling to the mqtt_helper library. 
 mqtt_helper.h can be found here: nrf\include
et\mqtt_helper.h 
 mqtt_helper.c can be found here: nrf\subsys
et\lib\mqtt_helper\mqtt_helper.c 
 The library already handles the username, and both the username and password are handled the same way by the underlying MQTT client library, so you should be able to just copy what the mqtt_helper library does with the username.
