modules

The random password is only returned if random is yes and the host did
not exist or update_password is yes.

If only one host is handled by the module, the returned dict is containing
this dict:

  { "randompassword": "<the host random password>" }

If several hosts are handled by the module (future feature):

  { "<host>": { "randompassword": "<the host random password>" } }

Fixes issue #134 (ipahost does not return the random password)
