Can we use external OIDC provider?

ecylmz

I will try the Kopano built packages and let you know.

Thanks.

Hi,

I encountered an error while using external OIDC provider.
When I log in using an external OIDC provider, the Konnect application fails.

Here’s my configuration:

# /etc/kopano/konnectd.cfg
oidc_issuer_identifier=https://mail.vagrant.ga
identifier_registration_conf = /etc/kopano/konnectd-identifier-registration.yaml
log_level = debug

# /etc/kopano/server.cfg
enable_sso = yes
kcoidc_issuer_identifier = https://mail.vagrant.ga
kcoidc_insecure_skip_verify = yes

# /etc/kopano/konnectd-identifier-registration.yaml

  - id: konnect

    identity_claim_name: sub
    scopes:

        define('OIDC_ISS', 'https://mail.vagrant.ga');
        define('OIDC_CLIENT_ID', 'konnect');
        define('OIDC_SCOPE', 'openid profile email kopano/gc');
...

Other options have default values.

Konnect log:

Thanks for testing. Looks like the response uses the fragment response mode which cannot work with server server side oidc. Since you used an implcit response type , the fragment more is the default and it seem that this cannot be configured yet in the authority configuration of Konnect. So maybe you can switch to code flow so that the callback includes the parameters as query. It should not be particularly hard to extend the authority configuration by an optional response_mode request parameter as well (so non-defaults, can be set).

I tried to switch code flow:

# /etc/kopano/konnectd-identifier-registration.yaml
...
authorities:
  - name: lemonldap
    default: yes
    iss: https://auth.sso.vagrant.ga
    client_id: konnect
    client_secret: konnect
    authority_type: oidc
    discover: true
    response_type: code
    insecure: true
    identity_claim_name: sub
    scopes:
      - openid
      - profile
      - email

No luck, i see the following error in the log:

The external OIDC provider configuration is as follows. Maybe it is useful information.

Is there anything I can do for this problem?

longsleep

Ok that is better but you can see that this code path is experimental.

The callback handler cannot parse the IDToken value - most likely because it is not returned since you provided response_type code.

So instead of code try code id_token - that should make the external provided return the IDToken value directly and since its still code flow, (technically hybrid flow) it should default to query mode.

Look at https://stash.kopano.io/projects/KC/repos/konnect/browse/identifier/handlers.go#679 to see the corresponding source code. It is not hard to fix if there should be still problems - pull requests welcome :)

ecylmz

I also tried to response_type: code id_token

I get this error again:

level=debug msg="identifier oauth2 cb without state" error="state not found"

Look at https://stash.kopano.io/projects/KC/repos/konnect/browse/identifier/handlers.go#679 to see the corresponding source code. It is not hard to fix if there should be still problems - pull requests welcome :)

It’s hard for me but i will try my best. :)

@ecylmz said in Can we use external OIDC provider?:

I get this error again

Well Response mode needs to be query. Check your external providers config - maybe the default can be changed there. If no IDToken returning response type can be found, this hits a blocker until the response mode can be configured on the konnect client side.

ecylmz

My external OIDC provider (LemonLDAP) doesn’t support query mode in implicit response_type. Their default is fragment. You can check theirs code: OpenIDConnect.pm#L326

I changed this line on LemonLDAP server:

my $response_url = "$redirect_uri#" with my $response_url = "$redirect_uri?.

So I thought it would support query mode.

And then, i changed my configuration like that:

---
# /etc/kopano/konnectd-identifier-registration.yaml

    name: OIDC Playground

define('OIDC_ISS', 'https://mail.sso.vagrant.ga');
define('OIDC_CLIENT_ID', 'webapp');
define('OIDC_SCOPE', 'openid profile email kopano/gc');

When i try to login kopano webapp(https://mail.sso.vagrant.ga), redirecting to lemonldap’s login page with these parameters:

https://auth.sso.vagrant.ga/oauth2/authorize?client_id=konnect&code_challenge=L0dUsCs-qks19uzY9o31STSRCuEKVksB4mDdz2R9wDA%3D&code_challenge_method=S256&nonce=YJO362T_NamOyLo5Y5LM5l0A8wm1DeMoN3CqtMAYs_c%3D&redirect_uri=https%3A%2F%2Fmail.sso.vagrant.ga%2Fsignin%2Fv1%2Fidentifier%2Foauth2%2Fcb&response_mode=query&response_type=id_token+token&scope=openid+profile+email&state=YquREhexvC5C90vDs7fqadLZSqU12MEW4HT4DPV0K8I%3D

When I enter my username and password, I get redirected to Konnect, but Konnect goes into an infinit redirect loop.

John is present in ldap and I can log in without SSO.

I’m still working on it.

@ecylmz said in Can we use external OIDC provider?:

level=warning msg=“identifier ignoring validation error for insecure authority” client_id=konnect error=“No kid header”

There is no kid claim in the JWT header of the IDToken provided by your external OIDC. It is required (see https://stash.kopano.io/projects/KC/repos/konnect/browse/identity/authorities/authorities.go#116) in this mode of operation.

I suggest you get in touch with our support since this experimental mode of operation is clearly currently lacking some bits and pieces here and there.

@ecylmz Were you able to get this functioning? I’m encountering a similar issue trying to let a 3rd party provider authenticate for Konnect (I was trying SAML), but wondered if you were successful with LLNG in one of its more recent releases (2.0.9 is out now).
