Overview of SSO

vCluster Platform supports all major Single-Sign-On (SSO) providers. To configure SSO for vCluster Platform, expand the desired SSO provider (for example Google, Okta, GitHub) field listed below and follow the instructions provided.

Domain Required

Most SSO provider connections do not allow localhost and require that you set up a domain for your vCluster Platform instance first.

SSO Configuration Examples

GitHub

Create A GitHub App
In GitHub, navigate to Settings > Developer Settings > OAuth Apps and create a new OAuth App with the following settings:
- Application name: vCluster Platform Login via GitHub
- Homepage URL: https://vcluster-platform.yourcompany.tld = https:// + $VCLUSTER_PRO_HOSTNAME
- Auth callback URL: https://vcluster-platform.yourcompany.tld/auth/github/callback = https:// + $VCLUSTER_PRO_HOSTNAME + /auth/github/callback
Remember the $GITHUB_CLIENT_ID and $GITHUB_CLIENT_SECRET that GitHub generates for your OAuth application because you will need it in the next step.

Create vCluster Platform Config For GitHub

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

auth:
  # Tell loft to use github authentication
  github:
    #
    #
    # REQUIRED CONFIGURATION
    #
    #
    # ClientID of the github application. Can be string literal or pulled from the environment.
    clientId: $CLIENTID
    # ClientSecret of the github application. Can be string literal or pulled from the environment.
    clientSecret: $CLIENTSECRET
    # Callback URL in the form of https://your-loft-domain/auth/github/callback
    redirectURI: https://vcluster-platform.my.domain/auth/github/callback
    #
    #
    # OPTIONAL CONFIGURATION
    #
    #
    # (Optional) vCluster Platform queries the following organizations for group information.
	# Group claims are formatted as "(org):(team)".
	# For example if a user is part of the "engineering" team of the "coreos"
	# org, the group claim would include "coreos:engineering".
	#
	# If orgs are specified in the config then user MUST be a member of at least one
	# of the specified orgs to authenticate with loft.
	orgs:
	  # Organization name in github (not slug, full name)
	- name: My Organization
	  # (Optional) Names of teams in a github organization. A user will be able to
	  # authenticate if they are members of at least one of these teams.
	  teams:
	  - myteam
    # (Optional) Required ONLY for GitHub Enterprise.
    # This is the Hostname of the GitHub Enterprise account listed on the
	# management console.
    hostName: my-github.org
    # (Optional) Required ONLY for GitHub Enterprise.
    # Used to support self-signed or untrusted CA root certificates.
    rootCA: /certs/github.ca

Authenticate via GitHub
After saving the new vCluster Platform configuration, vCluster Platform will restart and you should be able to log in via GitHub. Beware that only members of your organization on GitHub can sign in and that everyone must grant access to view their organization during the login process.
Must Grant Access To Organization
Users must grant access to the organization you configured dex for in step 2 above, otherwise they will not be able to log in.

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!)

SAML 2.0

Refresh Tokens

The SAML 2.0 connector in vCluster Platform does not support refresh tokens "since the SAML 2.0 protocol doesn't provide a way to requery a provider without interaction" (see dex documentation for SAML 2.0).

Create vCluster Platform Config For SAML v2.0

vCluster Platform is able to use SAML v2.0 flow to identify the end user.

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

auth:
  # Tell vCluster Platform to use saml authentication
  saml:
    #
    #
    # REQUIRED CONFIGURATION
    #
    #
    # SSO URL used for POST value.
    ssoURL: https://saml.example.com/sso
    # CA to use when validating the signature of the SAML response.
    ca: /path/to/ca.pem
    # CA's can also be provided inline as a base64'd blob.
    #
    # caData: ( RAW base64'd PEM encoded CA )
    # Callback URL in the form of https://your-vcluster-platform-domain/auth/saml/callback
    redirectURI: https://vcluster-platform.my.domain/auth/saml/callback
    # Name of attributes in the returned assertions to map to ID token claims.
    usernameAttr: name

    allowedGroups: ["Admins"]
    # (Optional) To skip signature validation, uncomment the following field. This should
    # only be used during testing and may be removed in the future
    insecureSkipSignatureValidation: true
    # (Optional) Manually specify vCluster Platform's Issuer value.
    # When provided vCluster Platform will include this as the Issuer value during AuthnRequest.
    # It will also override the redirectURI as the required audience when evaluating
    # AudienceRestriction elements in the response.
    entityIssuer: https://vcluster-platform.my.domain/auth/saml/callback
    # (Optional) Issuer value expected in the SAML response.
    ssoIssuer: https://saml.example.com/sso
    # (Optional) Delimiter for splitting groups returned as a single string.
    #
    # By default, multiple groups are assumed to be represented as multiple
    # attributes with the same name.
    #
    # If "groupsDelim" is provided groups are assumed to be represented as a
    # single attribute and the delimiter is used to split the attribute's value
    # into multiple groups.
    groupsDelim: ", "
    # (Optional) Requested format of the NameID.
    #
    # The NameID value is is mapped to the user ID of the user. This can be an
    # abbreviated form of the full URI with just the last component. For example,
    # if this value is set to "emailAddress" the format will resolve to:
    #
    #     urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
    #
    # If no value is specified, this value defaults to:
    #
    #     urn:oasis:names:tc:SAML:2.0:nameid-format:persistent
    #
    nameIDPolicyFormat: persistent

Authenticate via SAML
After saving the new vCluster Platform configuration, vCluster Platform will restart itself and you should be able to log in via SAML.

Disable Username + Password Authentication (optional)

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

LDAP

Choose DEX_HOSTNAME And Configure DNS
vCluster Platform uses the CNCF project dex for single sign-on.

The easiest case is this one:
- $VCLUSTER_PRO_HOSTNAME = vcluster-platform.mycompany.tld (where vCluster Platform is running)
- $DEX_HOSTNAME = dex.mycompany.tld (where dex should be running)

Create Dex Config For LDAP

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

ingress:
  enabled: true
  hosts:
    - host: dex.yourcompany.tld # Use $DEX_HOSTNAME
      paths:
        - path: /
config:
  issuer: https://dex.yourcompany.tld # "https://" + $DEX_HOSTNAME
  connectors:
    - type: ldap
      id: ldap
      name: LDAP
      config:
        host: myldap.company.tld:636 # Your LDAP server hostname:port
        # insecureNoSSL: true                               # Not recommended but required if not using TLS (port 389)
        # insecureSkipVerify: true                          # Not recommended but required for self-signed certificates
        # rootCAData: ( base64 encoded PEM file )
        # startTLS: true                                    # Use ldap:// instead of ldaps:// protocol

        # The DN and password for an application service account. The connector uses
        # these credentials to search for users and groups. Not required if the LDAP
        # server provides access for anonymous auth.
        # Please note that if the bind password contains a `$`, it has to be saved in an
        # environment variable which should be given as the value to `bindPW`.
        bindDN: uid=serviceaccount,cn=users,dc=example,dc=com
        bindPW: password

        # User search maps a username and password entered by a user to a LDAP entry.
        userSearch:
          # BaseDN to start the search from. It will translate to the query
          # "(&(objectClass=person)(uid=<username>))".
          baseDN: cn=users,dc=example,dc=com
          # Optional filter to apply when searching the directory.
          filter: "(objectClass=person)"
          # username attribute used for comparing user entries. This will be translated
          # and combined with the other filter as "(<attr>=<username>)".
          username: uid
          # The following three fields are direct mappings of attributes on the user entry.
          # String representation of the user.
          idAttr: uid
          # Required. Attribute to map to Email.
          emailAttr: mail
          # Maps to display name of users. No default value.
          nameAttr: name

        # Group search queries for groups given a user entry.
        groupSearch:
          # BaseDN to start the search from. It will translate to the query
          # "(&(objectClass=group)(member=<user uid>))".
          baseDN: cn=groups,dc=freeipa,dc=example,dc=com
          # Optional filter to apply when searching the directory.
          filter: "(objectClass=group)"
          # Represents group name.
          nameAttr: name
          # Following list contains field pairs that are used to match a user to a group. It adds an additional
          # requirement to the filter that an attribute in the group must match the user's
          # attribute value.
          userMatchers:
            - userAttr: uid
              groupAttr: member
  staticClients:
    - name: vCluster Platform
      id: loft # Define a $DEX_CLIENT_ID
      secret: XXXXXXXXXXXXXX # Define a $DEX_CLIENT_SECRET (can be any secret key)
      redirectURIs:
        - "https://vcluster-platform.mycompany.tld/auth/oidc/callback" # vCluster Platform URL + /auth/oidc/callback
  oauth2:
    skipApprovalScreen: true
  web:
    http: 0.0.0.0:5556
  storage:
    type: kubernetes
    config:
      inCluster: true

For details about configuring dex for LDAP, take a look at the dex documentation for LDAP.

Deploy Dex via Helm

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

helm install dex dex --repo https://charts.dexidp.io \
  --create-namespace --namespace dex \
  -f dex-config.yaml \
  --wait

Configure vCluster Platform To Use Dex For Authentication

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

    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 vCluster Platform username (default: email)
    usernamePrefix: "" # Optional: Add prefix to usernameClaim for vCluster Platform 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 vCluster Platform container (default: '')

Authenticate via Dex + LDAP
After saving the new vCluster Platform configuration, vCluster Platform will restart itself and you should be able to log in via LDAP and dex.

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!)

Check the official artifacthub.io page for all available options.

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:

Deploy Dex via Helm

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

helm install dex dex --repo https://charts.dexidp.io \
  --create-namespace --namespace dex \
  -f dex-config.yaml \
  --wait

Configure vCluster Platform To Use Dex For Authentication

To tell vCluster Platform to use dex for SSO, navigate to Admin > Config in vCluster Platform 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 vCluster Platform username (default: email)
    usernamePrefix: "" # Optional: Add prefix to usernameClaim for vCluster Platform 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 vCluster Platform container (default: '')

Authenticate via Dex + $OTHER_PROVIDER
After saving the new vCluster Platform configuration, vCluster Platform will restart itself and you should be able to log in via $OTHER_PROVIDER and dex.

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

Multiple SSO Providers

In vCluster Platform, you can also configure multiple SSO providers together. This can be a very handy feature if you have multiple groups using different authentication providers based on team or geographical region. Configuration of multiple SSO providers of the same type is also possible. The latter is configured by using the "connectors" option. Below is an example vCluster Platform config "auth" section that contains three SSO providers (one OIDC, and two GitHub providers). When users log into vCluster Platform with such a configuration present, they will see three options for authentication as well as the default user/password box (which can be disabled if desired).

auth:
  github:
    clientId: test123
    clientSecret: test123
    redirectURI: https://my-vcluster-platform-url/auth/github/callback
  oidc:
    clientId: test
    clientSecret: test
    issuerUrl: https://example-issuer.com
    redirectURI: https://my-vcluster-platform-url/auth/oidc/callback
  # If you want to use multiple SSO configs of the same type you can use the connectors option
  connectors:
    # the id of the connector that will show up in the vcluster-platform callback url
    - id: test
      # name to show in the UI
      displayName: Test GitHub
      # any regular sso config
      github:
        clientId: test
        clientSecret: test
        # Make sure to exchange test here with the connector id if you change that
        redirectURI: https://my-vcluster-platform-url/auth/test/callback
