amqp1.0 using sasl PLAIN

Hi Microsoft,

currently im developing my own amqp1.0 client, i have done with basic implementation , Now started implementing SASL support for my amqp client, I started with SASL PLAIN and took help of rabbitmq as my broker with plugin enabled to support 1.0

please find the attached wireshark logs in link 

let me know am i missing anything, in my log i see version negotiation, sasl negotiation,version negotiation, amqp open, is success but i didnt understood why amqp session is failed in this case broker is replying with amqp close.

Please help me in understanding the issue.
