Address = {A,B,C,D} | string() | undefined
Dir = string()
AuthPassword =string()
Reason = term()

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

Dir = string()
GroupName = string()
AuthPassword = string()
Reason = term()

delete_group/2, delete_group/3, and delete_group/4 each deletes the group specified and returns true. If there is an error, {error, Reason} is returned. When delete_group/2 is called, option Port and Dir are mandatory.

delete_group_member(GroupName, UserName, Options) -> true | {error, Reason}

Dir = string()
AuthPassword = string()
Reason = term()

delete_group_member/3, delete_group_member/4, and delete_group_member/5 each deletes a user from a group. If the group or the user does not exist, this function returns an error, otherwise true. When delete_group_member/3 is called, the options Port and Dir are mandatory.

delete_user(UserName,Options) -> true | {error, Reason}
delete_user(UserName, Port, Dir) -> true | {error, Reason}
delete_user(UserName, Address, Port, Dir) -> true | {error, Reason}

Types:
