# PCP QA Test No. 823
# Exercise basic SASL functionality using a custom sasldb.
#
# Copyright (c) 2013 Red Hat.
#
# NOTE
#	This test is likely to fail unless hostname(1) returns
#	some sort of FQDN.  For example, when hostname was vm23 it
#	failed, but when hostname was set (via /etc/hostname in
#	this case) to vm23.localdomain the test passes.
