HOST =      "localhost"
USER =      os.environ.get("LMI_CIMOM_USERNAME", "root")
PASSWD =    os.environ.get("LMI_CIMOM_PASSWORD", "blank")

def id_generator(size=6, chars=string.ascii_uppercase + string.digits):
   return ''.join(random.choice(chars) for x in range(size))
#setup
conn = lmishell.connect(HOST, USER, PASSWD)
cs = conn.root.cimv2.PG_ComputerSystem.first_instance()
lams = conn.root.cimv2.LMI_AccountManagementService.first_instance()

#create
myuser = "lmishell-user" + id_generator(18)
print myuser
user = lams.CreateAccount(Name=myuser, System=cs)

user_mod = conn.root.cimv2.LMI_Account.first_instance({"Name" : myuser})
grp_mod = conn.root.cimv2.LMI_Group.first_instance({"Name": myuser})
print user_mod.DeleteUser()
print grp_mod.DeleteGroup()
