Other Auth Providers

Loft supports a variety of other auth providers. You can follow this generic guide to configure SSO for any of the auth providers, including:

Microsoft
Google
OpenID Connect
OpenShift
LinkedIn
AuthProxy
Bitbucket Cloud
Atlassian Crowd
Gitea

STEP 1

Choose DEX_HOSTNAME And Configure DNS

Loft uses the CNCF project dex for single sign-on.

The easiest case is this one:

$LOFT_HOSTNAME = loft.mycompany.tld (where Loft is running)
$DEX_HOSTNAME = dex.mycompany.tld (where dex should be running)

STEP 2

Create Dex Config For $OTHER_PROVIDER

Create the file dex-config.yaml with the following dex configuration:

ingress:
  enabled: true
  hosts:
  - dex.yourcompany.tld                                   # Use $DEX_HOSTNAME
config:
  issuer: https://dex.yourcompany.tld                     # "https://" + $DEX_HOSTNAME
  connectors:
  - {YOUR_CONNECTOR_CONFIG}                               # SEE LINKS BELOW! (do not remove the '-' and indent correctly)
  staticClients:
  - name: Loft
    id: loft                                              # Define a $DEX_CLIENT_ID
    secret: XXXXXXXXXXXXXX                                # Define a $DEX_CLIENT_SECRET (can be any secret key)
    redirectURIs:
    - 'https://loft.mycompany.tld/auth/oidc/callback'     # Loft URL + /auth/oidc/callback
  oauth2:
    skipApprovalScreen: true
  web:
    http: 0.0.0.0:5556
  storage:
    type: kubernetes
    config:
      inCluster: true

To fill the connectors section shown above, go to the appropriate docs page for the auth provider you want to use in combination with dex:

STEP 3

Deploy Dex via Helm

After creating the file dex-config.yaml, you can now install dex via helm:

helm install dex dex --repo https://wiremind.github.com/wiremind-helm-charts \
  --create-namespace --namespace dex \
  -f dex-config.yaml \
  --wait

STEP 4

Configure Loft To Use Dex For Authentication

To tell Loft to use dex for SSO, navigate to Admin > Config in Loft and adjust your config as shown below:

auth:
  oidc:
    issuerUrl: https://dex.mycompany.tld  # Use $DEX_HOSTNAME (see above)
    clientId: ""                          # Use $DEX_CLIENT_ID (see above)
    clientSecret: ""                      # Use $DEX_CLIENT_SECRET (see above)
    type: "github"                        # Optional: SSO Login Button Icon ("", github, gitlab, microsoft, google)
    usernameClaim: "email"                # Optional: Which part of the dex token to use as Loft username (default: email)
    usernamePrefix: ""                    # Optional: Add prefix to usernameClaim for Loft username
    groupsClaim: "groups"                 # Optional: Add Kubernetes groups for this user
    groupsPrefix: "loft-"                 # Optional: Prefix for Kubernetes groups
    caFile: ""                            # Optional: Path to a CA cert of dex within the Loft container (default: '')

STEP 5

Authenticate via Dex + $OTHER_PROVIDER

After saving the new Loft configuration, Loft will restart itself and you should be able to log in via $OTHER_PROVIDER and dex.

STEP 6

Disable Username + Password Authentication (optional)

To disable password-based authentication, navigate to Admin > Config add these two lines to your config:

auth:
  oidc: ...             # This is your SSO configuration (make sure this is working!)
  password:
    disabled: true      # Disable password-based authentication
