The GitHub credential provider allows authentication via GitHub.
|
|
|
|
Users provide a personal access token to log in, and the credential
|
|
provider verifies they're part of the correct organization and then
|
|
maps the user to a set of Vault policies according to the teams they're
|
|
part of.
|
|
|
|
After enabling the credential provider, use the "config" route to
|
|
configure it.
