Second Life Login API Strawman
This is a work in progress. Also see a similar Strawman by AWG: AWG_flows_login Innitial meeting with AWG to request feedback on protocol: Feedback Chat-log, 19 Feb 2008
Introduction
This page attempts to merge Authentication_Flow with Current_login_protocols and adds additional protocol changes to fit with Agent_Domain#How_login_works. The goal is to expose a protocol allowing login to a separate region domain while making incremental, small changes to the current protocol.
Summary
- *Viewer sends credentials to the Login Service #Login_Web_Service
- Login Service authenticates and sets up and queries for presence:
- Queries the agent data from the Agent Store.
- Finds an agent host, POST's agent presence checking for already online
- grants seed capability, which lives on an agent host
- *Viewer requests capabilities needed for login via received seed capability. #Seed_Capability
- *(future) Viewer Polls Agent Host for messages via long-poll #poll_for_messages_Capability
- *(future) Viewer can send instant messages before being in world. #instant_message_Capability
- *Viewer invokes legacy_login capability #legacylogin_Capability
- Initialization data returned by login
- Sets up agent presence
- Forwards location request to region domain, finding a region to rez the avatar
- Establishes session with region host, which gives back a seed capability to the client
- *Viewer invokes region seed capability
Definitions
Seed Capability
The current Login Seed Capability is a Capability associated with the simulator you are logging into. It should not be confused with the Seed-Capability proposed for the new protocols.
Agent Seed Capability
This is a newly introduced capability associated with the agent host as part of the agent domain. This is different from the previously mentioned seed-capability, which associates with the sim host as part of the region domain.
Conventions
On this page the following conventions are used:
- "in quotes is a literal string"
- [ represents a list of choices | separated by a vertical bar ]
- < represents a value which can be substituted by an appropriate string described inside >
- 'represents a string that must be quoted, but how will be implementation specific' for example in LSL "" denotes a string and " will be used in place of the single quote (').
- + means to concatenate the two parts, though how will be implementation specific, for example + can be used to concatenate strings.
Login Web Service
Client --> public Login Server: "Here is my credential, and optional agent identity desired" Second Life Login Server: https://login.agni.secondlife.com/app/login/
Required Parameters
{ 'credential': { 'type': 'agent',
'first_name': <first>,
'last_name': <last>,
'password': '$1$' + <passwd_md5> } }
OR (future)
{ 'credential': { 'type': 'account',
'account_name': <IBM>,
'password': '$1$' + <passwd_md5> } }
OR (future)
{ 'credential': { 'type': 'openid',
'url': <URL> } }
OR (future)
{ 'credential': { 'type': 'agent',
'first_name': <first>,
'last_name': <last>}}
which will need to a challenge from the auth system.
Optional Parameters
Optionally, specify which account you want this credential to log you into
{ 'credential': { 'type': 'agent',
'first_name': <first>,
'last_name': <last>,
'password': '$1$' + <passwd_md5> },
'first_name': <first>,
'last_name': <last> }
Response
Response Codes : Response 200 : Successful authentication.
{ 'agent seed-capability' : <url> -- agent domain seed capability] }
4xx : If this credential has more than one account linked to it, and no specific account was specified in the optional parameters, the response will list a set of accounts to choose from.
{ 'reason': 'select account', -- reason why authentication failed
'accounts' : [ { 'first_name' : <first>, 'last_name' : <last> },
{ 'first_name' : <first>, 'last_name' : <last> },
... ] }
4xx : Unsuccessful authentication due to need for more information.
{ 'reason': 'tos'|'critical'|'more info', -- reason why authentication failed
'redirect' : <url> } -- URL to visit to get more information on how to proceed
Other reasons:
* no agent * bad identity and authentication information * agent not enabled (banned)
5xx : Server unavailable.
{ 'reason': 'generic' }
Seed Capability
Client -> Agent Host (via seed cap): "I want cap X"
- This service supports named capabilities for the agent domain requested by the client
Required Parameters
Map of named capabilities to Options
{ <capability name> : { 'enabled' : 'true' | 'false' },
<capability name> : { 'enabled' : 'true' | 'false' },
..., etc. ]
<- Ok, here's the cap to do X
-or-
<- Bzzzp, you don't get to do X
Response
Map of capability name to capability URL:
{ <capability name> : <url>, <capability name> : <url>, ... etc. }
Example: Basic Login Capabilities
POST data:
{ 'establish_presence' : { 'enabled' : 'true' },
'inventory' : { 'enabled' : 'true' },
'non_existent_cap' : { 'enabled' : 'false' },
'be_in_world' : { 'enabled' : 'true' } }
Response value:
{ 'establish_presence' : <cap GO>, 'inventory' : <cap I>, 'be_in_world' : <cap CTR> }
legacy_login Capability
- Viewer -> Agent Host (via cap LL): "I'd like to log in using the legacy login protocols"
Required Parameters
{ 'start': ["first" | "last" | uri:<existing region name>&<x>&<y>&<z> ],
"channel": <channel>,
"version": <client version>,
"platform": ["Lin" | "Mac" | "Win"]
"mac": <MAC Address>,
"options": <array of strings>,
"id0": <uuid>,
"agree_to_tos": ["true" | "false" | ""],
"read_critical": ["true" | "false" | ""],
"viewer_digest": <uuid>,
"options" : <array of strings> }
start -- attempt to log in to this sim, though if it is full or not available, or the agent is not allowed, another sim will be selected by the grid from its list of choices. "First" means home location. If home is filled then the grid will try last. If last is filled and home is set, the grid will try home. In either case the last choice will be from a list of telehubs. channel the name of the client. Used to differentiate official viewers from third party clients. options (See below) id0 hardware hash (based on the serial number of the first hard drive in Windows) used for uniquely identifying computers. viewer_digest MD5 hash of the viewer executable, only relevant when the channel is set to an official Second Life viewer.
Optional Parameters
The "options" key points to an array of optional options. Zero or more of the following character strings may appear in any order in the array:
{ 'options' : <"inventory-root" | "inventory-skeleton" | "inventory-lib-root" |
"inventory-lib-owner" | "inventory-skel-lib" | "gestures" | "event_categories" |
"event_notifications" | "classified_categories" | "buddy_list" | "ui-config" |
"login-flags" | "global-textures">* }
inventory-root UUID of the root inventory folder in the client's inventory window inventory-skeleton "starter kit" inventory: name, folder_id, parent_id, type_default, version of all folders inventory-lib-root folder_id of library root inventory folder inventory-lib-owner agent_id of owner for inventory lib inventory-skel-lib LL supplied library of inventory items: same as inventory-skeleton, except global inventory gestures list of item_id, asset_id pairs for active gestures event_categories list of different event categories event_notifications list of events for which you have notifications classified_categories" return a list of classifieds categories buddy-list agent_id, granted rights and given rights of everyone that is your buddy ui-config list of UI enabled/disabled states, currently: allow_first_life ('Y' or 'N') for teens login-flags if set, return 'stipend_since_login', 'ever_logged_in', 'gendered', and 'daylight_savings' values global-textures Texture UUIDs for global textures
