20 Tests for source4/dsdb/samdb/ldb_modules/password_hash.c
22 These tests are designed to also run against Windows to confirm the values
23 returned from Windows.

26 Set the following environment variables:
27 PASSWORD=Administrator password
28 USERNAME=Administrator
29 SMB_CONF_PATH=/dev/null
31 SERVER=Windows server IP
33 /usr/bin/python source4/scripting/bin/subunitrun
