Mistake in Username in env file leads to NetworkError #792
Description
I am using PRC 3.2.0 and I am connecting to an SSL enabled iRODS instance which uses the pam module to authenticate users.
When I use a wrong username in my irods environment file, the PRC throws a NetworkError while as a user I would expect a CAT_INVALID_USER or CAT_INVALID_AUTHENTICATION:
CRITICAL:irods.connection:Read 0 bytes from socket instead of expected 4 bytes
ERROR:irods.connection:Could not receive server response
