34              add_group_member/3,  add_group_member/4,  and add_group_member/5
35              each adds a user to a group. If the group does not exist, it  is
36              created  and  the  user  is  added to the group. Upon successful
37              operation, this function returns true. When  add_group_members/3
38              is called, options Port and Dir are mandatory.

61              add_user/2,  add_user/5,  and add_user/6 each adds a user to the
62              user database. If the operation  is  successful,  this  function
63              returns  true.  If  an error occurs, {error,Reason} is returned.
64              When add_user/2 is called, options Password, UserData, Port, and
65              Dir are mandatory.

83              delete_group/2,  delete_group/3, and delete_group/4 each deletes

110              group or the user does  not  exist,  this  function  returns  an

238
239              update_password/5 and update_password/6 each updates AuthAccess‐
240              Password for the specified directory. If NewPassword is equal to
241              "NoPassword", no password is required  to  change  authorisation
242              data. If NewPassword is equal to "DummyPassword", no changes can
243              be done without changing the password first.
