# tarantool-authman

[![Build Status](https://travis-ci.org/mailru/tarantool-authman.png?branch=master)](https://travis-ci.org/mailru/tarantool-authman)

This module provides api for registration and login users in your site (or any other system).
Supports login with email/password and socials (facebook.com, vk.com, google.com).
It also provides api that helps to build OAuth2 authentication service,
i.e. methods to manage OAuth entities such as OAuth client, authorization code and access token.

Requires tarantool >= 1.7.4.168

## Installation

Using tarantoolctl:
```
$ tarantoolctl rocks install authman
```

Also available `.rpm` and `.deb` packages:
```
# CentOS
$ yum install tarantool-authman

# Ubuntu
$ apt-get install tarantool-authman
```

## Quickstart
Create tarantool instance file /etc/tarantool/instances.available/tarantool-authman.lua:
```
box.cfg {
listen = 3302,
}

local config = {
-- configuration table, details below
}
auth = require('authman').api(config)

```
Create symlink in /etc/tarantool/instances.enabled:
```
$ ln -s /etc/tarantool/instances.available/tarantool-authman.lua .
```

Run tarantool and connect to it:
```
$ tarantoolctl start tarantool-authman
$ tarantoolctl enter tarantool-authman

```

Use auth api:
```
tarantool> ok, user = auth.registration('example@mail.ru')
tarantool> ok, user = auth.complete_registration('example@mail.ru', user.code, 'Pa$$wOrD')
tarantool> ok, user = auth.set_profile(user['id'], {first_name='name', laste_name='surname'})
tarantool> ok, user = auth.auth('example@mail.ru', 'Pa$$wOrD')
tarantool> session = user['session']
tarantool> ok, user = auth.check_auth(session) -- user can get new session
```

## Configuration
Example of my_config.lua module, fill empty strings with your values:
```
return {
activation_secret = '',
session_secret = '',
restore_secret = '',
session_lifetime = 7 * 24 * 60 * 60,
session_update_timedelta = 2 * 24 * 60* 60,
social_check_time = 60 * 60* 24,

-- password_strength can be:
-- none, whocares, easy, common, moderate, violence, nightmare,
password_strength = 'common', -- default value

facebook = {
client_id = '',
client_secret = '',
redirect_uri='',
},
google = {
client_id = '',
client_secret = '',
redirect_uri=''
},
vk = {
client_id = '',
client_secret = '',
redirect_uri='',
},
}
```

## Documentation for OAuth2 related API

[OAuth2](doc/oauth2.md)

## Handling errors:

If first parametr (ok - bool) is false then error is occured. Error description will be stored in second param like:
```
error = {code = description}
```
Example:
```
tarantool> ok, user = auth.registration('aaa@mail.ru')
tarantool> ok
- false
tarantool> user
- '2': User already exists
```
Complete list of error codes:
```
error.USER_NOT_FOUND = '1'
error.USER_ALREADY_EXISTS = '2'
error.INVALID_PARAMS = '3'
error.USER_NOT_ACTIVE = '4'
error.WRONG_PASSWORD = '5'
error.WRONG_ACTIVATION_CODE = '6'
error.WRONG_SESSION_SIGN = '7'
error.NOT_AUTHENTICATED = '8'
error.WRONG_RESTORE_TOKEN = '9'
error.USER_ALREADY_ACTIVE = '10'
error.WRONG_AUTH_CODE = '11'
error.IMPROPERLY_CONFIGURED = '12'
error.WRONG_PROVIDER = '13'
error.WEAK_PASSWORD = '14'
error.SOCIAL_AUTH_ERROR = '15'
error.OAUTH_APP_ALREADY_EXISTS = '16'
error.OAUTH_APP_NOT_FOUND = '17'
error.OAUTH_CONSUMER_NOT_FOUND = '18'
