# This test is run in environment with two DCs ('localdc' and 'localvampiredc')
# The 'net ads join' has these two steps:
#   1. create machine account at DC ('-S' points to 'localvampiredc')
#   2. create keytab and sync the KVNO from a DC
#
# It must be ensured that in step #2 the keytab code contacts the same DC
# ('localvampiredc'). The configuration below tries to break it.
# We disable [SAF/DOMAIN/...] and [SAFJOIN/DOMAIN/...] by setting TTL to '-1'
# And via setting 'password server' to 'localdc' we manage that
# get_dc_list() returns 'localdc' instead of 'localvampiredc'
#
# As long as the keytab code is not explicitly told to use the same DC as join,
# we get failure:
# gensec_gse_client_prepare_ccache: Kinit for F0D26C71F6$@SAMBA.EXAMPLE.COM to access ldap/localdc.samba.example.com failed: Client not found in Kerberos database: NT_STATUS_LOGON_FAILURE
