# Configuring Connectors
|
|
|
|
Connectors connect dex to authentication providers. dex needs to have at least one connector configured so that users can log in.
|
|
|
|
## Configuration Format
|
|
|
|
The dex connector configuration format is a JSON array of objects, each with an ID and type, in addition to whatever other configuration is required, like so:
|
|
|
|
```
|
|
[
|
|
{
|
|
"id": "local",
|
|
"type": "local"
|
|
}, {
|
|
"id": "Google",
|
|
"type": "oidc",
|
|
...<<more config>>...
|
|
}
|
|
]
|
|
```
|
|
|
|
The additional configuration is dependent on the specific type of connector.
|
|
|
|
### `local` connector
|
|
|
|
The `local` connector allows email/password based authentication hosted by dex itself. It is special in several ways:
|
|
|
|
* There can only be one `local` connector in your configuration.
|
|
* The id must be `local`
|
|
* No other configuration is required
|
|
|
|
When the `local` connector is present, users can authenticate with the "Log in With Email" button on the authentication screen.
|
|
|
|
The configuration for the local connector is always the same; it looks like this:
|
|
|
|
```
|
|
{
|
|
"id": "local",
|
|
"type": "local"
|
|
}
|
|
```
|
|
|
|
### `oidc` connector
|
|
|
|
This connector config lets users authenticate with other OIDC providers. In addition to `id` and `type`, the `oidc` connector takes the following additional fields:
|
|
|
|
* issuerURL: a `string`. The base URL for the OIDC provider. Should be a URL with an `https` scheme.
|
|
|
|
* clientID: a `string`. The OIDC client ID.
|
|
|
|
* clientSecret: a `string`. The OIDC client secret.
|
|
|
|
* trustedEmailProvider: a `boolean`. If true dex will trust the email address claims from this provider and not require that users verify their emails.
|
|
|
|
In order to use the `oidc` connector you must register dex as an OIDC client; this mechanism is different from provider to provider. For Google, follow the instructions at their [developer site](https://developers.google.com/identity/protocols/OpenIDConnect?hl=en). Regardless of your provider, registering your client will also provide you with the client ID and secret.
|
|
|
|
When registering dex as a client, you need to provide redirect URLs to the provider. dex requires just one:
|
|
|
|
```
|
|
https://$DEX_HOST:$DEX_PORT/auth/$CONNECTOR_ID/callback
|
|
```
|
|
|
|
`$DEX_HOST` and `$DEX_PORT` are the host and port of your dex installation. `$CONNECTOR_ID` is the `id` field of the connector for this OIDC provider.
|
|
|
|
Here's what a `oidc` connector looks like configured for authenticating with Google; the clientID and clientSecret shown are not usable. We consider Google a trusted email provider because the email address that is present in claims is for a Google provisioned email account (eg. an `@gmail.com` address)
|
|
|
|
```
|
|
{
|
|
"type": "oidc",
|
|
"id": "google",
|
|
"issuerURL": "https://accounts.google.com",
|
|
"clientID": "$DEX_GOOGLE_CLIENT_ID",
|
|
"clientSecret": "$DEX_GOOGLE_CLIENT_SECRET",
|
|
"trustedEmailProvider": true
|
|
}
|
|
```
|
|
|
|
## Setting the Configuration
|
|
|
|
To set a connectors configuration in dex, put it in some temporary file, then use the dexctl command to upload it to dex:
|
|
|
|
```
|
|
dexctl -db-url=$DEX_DB_URL set-connector-configs /tmp/dex_connectors.json
|
|
```
