# This test checks following use-cases:
# * SMPP interface of SMSC accepts SMPP clients (ESMEs) with password previously
#   defined in its configuration file.
# * When SMS is sent in 'store & forward' mode, ESME fails to send an SMS to non registered MS.
# * When SMS is sent in 'store & forward' mode, ESME can send an SMS to a not yet registered MS.
# * When SMS is sent in 'store & forward' mode, ESME can send an SMS to an already registered MS.
# * When SMS is sent in 'store & forward' mode, ESME receives a SMS receipt if it asked for it.
