Some identity providers like GitLab do not provide
information about group membership as part of the
identity token claims. They only expose it via OIDC compatible
'/oauth/userinfo' endpoint, as described in the OpenID
Connect 1.0 sepcification.
But this of course requires application to make sure to add
additional accessToken, since idToken cannot be re-used to
perform the same 'userinfo' call. This is why this is specialized
requirement. Gitlab seems to be the only OpenID vendor that requires
this support for the time being.

This commit adds a new STS API for X.509 certificate
authentication.
A client can make an HTTP POST request over a TLS connection
and MinIO will verify the provided client certificate, map it to an
S3 policy and return temp. S3 credentials to the client.
So, this STS API allows clients to authenticate with X.509
certificates over TLS and obtain temp. S3 credentials.
For more details and examples refer to the docs/sts/tls.md
documentation.

Some incorrect setups might have multiple audiences
where they are trying to use a single authentication
endpoint for multiple services.
Nevertheless OpenID spec allows it to make it
even more confusin for no good reason.
> It MUST contain the OAuth 2.0 client_id of the
> Relying Party as an audience value. It MAY also
> contain identifiers for other audiences. In the
> general case, the aud value is an array of case
> sensitive strings. In the common special case
> when there is one audience, the aud value MAY
> be a single case sensitive string.
fixes#12809
- ParentUser for OIDC auth changed to `openid:`
instead of `jwt:` to avoid clashes with variable
substitution
- Do not pass in random parents into IsAllowed()
policy evaluation as it can change the behavior
of looking for correct policies underneath.
fixes#12676fixes#12680
Additional support for vendor-specific admin API
integrations for OpenID, to ensure validity of
credentials on MinIO.
Every 5minutes check for validity of credentials
on MinIO with vendor specific IDP.
This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
LDAPusername is the simpler form of LDAPUser (userDN),
using a simpler version is convenient from policy
conditions point of view, since these are unique id's
used for LDAP login.
OpenID connect generated service accounts do not work
properly after console logout, since the parentUser state
is lost - instead use sub+iss claims for parentUser, according
to OIDC spec both the claims provide the necessary stability
across logins etc.
Fixes support for using multiple base DNs for user search in the LDAP directory
allowing users from different subtrees in the LDAP hierarchy to request
credentials.
- The username in the produced credentials is now the full DN of the LDAP user
to disambiguate users in different base DNs.
Bonus also fix a bug where we did not purge relevant
service accounts generated by rotating credentials
appropriately, service accounts should become invalid
as soon as its corresponding parent user becomes invalid.
Since service account themselves carry parent claim always
we would never reach this problem, as the access get
rejected at IAM policy layer.
not all claims need to be present for
the JWT claim, let the policies not
exist and only apply which are present
when generating the credentials
once credentials are generated then
those policies should exist, otherwise
the request will fail.
Additionally also fix STS logs to filter out LDAP
password to be sent out in audit logs.
Bonus fix handle the reload of users properly by
making sure to preserve the newer users during the
reload to be not invalidated.
Fixes#9707Fixes#9644Fixes#9651
Groups information shall be now stored as part of the
credential data structure, this is a more idiomatic
way to support large LDAP groups.
Avoids the complication of setups where LDAP groups
can be in the range of 150+ which may lead to excess
HTTP header size > 8KiB, to reduce such an occurrence
we shall save the group information on the server as
part of the credential data structure.
Bonus change support multiple mapped policies, across
all types of users.
allow generating service accounts for temporary credentials
which have a designated parent, currently OpenID is not yet
supported.
added checks to ensure that service account cannot generate
further service accounts for itself, service accounts can
never be a parent to any credential.
For a non-existent user server would return STS not initialized
```
aws --profile harsha --endpoint-url http://localhost:9000 \
sts assume-role \
--role-arn arn:xxx:xxx:xxx:xxxx \
--role-session-name anything
```
instead return an appropriate error as expected by STS API
Additionally also format the `trace` output for STS APIs
In certain organizations policy claim names
can be not just 'policy' but also things like
'roles', the value of this field might also
be *string* or *[]string* support this as well
In this PR we are still not supporting multiple
policies per STS account which will require a
more comprehensive change.
- adding oauth support to MinIO browser (#8400) by @kanagaraj
- supports multi-line get/set/del for all config fields
- add support for comments, allow toggle
- add extensive validation of config before saving
- support MinIO browser to support proper claims, using STS tokens
- env support for all config parameters, legacy envs are also
supported with all documentation now pointing to latest ENVs
- preserve accessKey/secretKey from FS mode setups
- add history support implements three APIs
- ClearHistory
- RestoreHistory
- ListHistory
- add help command support for each config parameters
- all the bug fixes after migration to KV, and other bug
fixes encountered during testing.
This change is related to larger config migration PR
change, this is a first stage change to move our
configs to `cmd/config/` - divided into its subsystems
