Getting Login exception (CLISession) while making session with SSH enable device with non admin user(Without root user)

Hi Team,

I am getting issue in when I am making the connection with ssh device with non admin user. its working fine with root user. We have a device which is SSH enabled, In this first make the CLISession for port forwarding and then connect the device. 
We are using the CLISession API to make the ssh connection with device. We are getting below exception:

We have provided correct non admin user name and password. 

Can you please let us know what is the root cause for above exception. Is there any limitation for non admin user to make the CLISession.
