No username/password send in body with oatuh2 authentication

[guilranc]

Hello and thanks a lot for work.
When i use oauth2 authentication with my creds, the correct POST is done to the token URL but return 422 status_code.
I extract the request on the api server and the body contains only : grant_type=client_credentials but there are not username and password.
Is there a trouble ?
Or i don't know how the http step plugin send this information for validate oauth2 authentication !?
Thanks !

it seems the plugin passes the client id and secret as basic auth in in the Authorization header:

http-step/src/main/java/edu/ohio/ais/rundeck/util/OAuthClient.java

Line 127 in 576f883

.setHeader(HttpHeaders.AUTHORIZATION, "Basic " + com.dtolabs.rundeck.core.utils.Base64.encode(this.clientId + ":" + this.clientSecret))
