--------------------------------
Summary: Identity Broker API
Key: KNOX-929
URL: https://issues.apache.org/jira/browse/KNOX-929
Project: Apache Knox
Issue Type: Bug
Components: Server
Reporter: Larry McCay
Fix For: 0.13.0
Ability to request a token on behalf of another user w/ cryptographically
verifiable trust relationship. This is essentially an extension of the
KnoxToken service where the username of the authenticated user is presented and
the resulting token should represent
Ability to specify what type of token is being requested. There are use cases
where Knox may be expected to interact with another STS service in order to
acquire another token. This may need to be addressed as a separate REST
resource and API or perhaps it can be a subtype of a more generic token
response. Current KnoxToken API response looks something like:
{
"access_token":"eyJhbGciOiJSUzI1NiJ9.
eyJzdWIiOiJndWVzdCIsImF1ZCI6InRva2VuYmFzZWQiLCJpc3MiOiJLTk9YU1NPIiwiZXhwIjoxNDkzNTM4MjY1fQ.

lmarJPjz9K_6sDgrgpZnVQhUfHUG3k6-zetqzKZhu3gZYVLfu36TXb3C62TfXIrPF2qI9psM",
"target_url":"https://localhost:8443/gateway/tokenbased";,
"token_type":"Bearer ",
"expires_in":1493538265484
}
It is possible that the above could be used to represent multiple token types
by adding additional token_type values for the client to interrogate and handle
appropriately.
Of course, a client should request a token from a KnoxToken service that is
configured to provide the desired token.
Perhaps, we limit an endpoint to a single token_type or we could configure a
single service endpoint to service requests for certain types and rely on the
client to ask for the desired one and default to current 'Bearer' type.
Where 'Bearer' implies our Knox JWT token.
Other potential types would include things like S3 or AWS tokens.
We may also want to consider base64 encoding the token for certain types.
Clients would have to know whether it needs to be decoded based on the type.
