 When a user logs in through dex, the user's identity is usually stored in another user-management system: a LDAP directory, a GitHub org, etc. Dex acts as a shim between a client app and the upstream identity provider. The client only needs to understand OpenID Connect to query dex, while dex implements an array of protocols for querying other user-management systems.

 A "connector" is a strategy used by dex for authenticating a user against another identity provider. Dex implements connectors that target specific platforms such as GitHub, LinkedIn, and Microsoft as well as established protocols like LDAP and SAML.

 # Running a Dex gRPC client
 
-Using gRPC, a client application can directly call methods on a server application as if it was a local object. The schema for Dex's gRPC API calls is defined in [`api/api.proto`][api-proto]. [`client.go`][client] is an example client program that makes a bunch of API calls to the dex server. For further details on the Dex API refer [`Documentation/api.md`][api-docs].
