Justification: renders package unusable
Using an /etc/nsswitch.conf line as follows:

(with the libnss-lwres 0.93-4 package installed), sshd will hang after
accepting but before authenticating a connection.
On the client side, the last bit of ssh verbosity is:
debug1: SSH2_MSG_NEWKEYS received
debug1: done: ssh_kex2.
debug1: send SSH2_MSG_SERVICE_REQUEST
