That's because you are setting tags = [] in 
https://github.com/simmel/rabbitmq-auth-backend-kerberos/blob/5eaccf20f13032f35b4d81c74ec2af24f9a4c974/src/rabbit_auth_backend_kerberos.erl#L28

You'll probably want to invoke 
rabbit_auth_backend_internal:lookup_user(Username) and extract the tags 
from the result.

Matthias.
