Summary
refresh_token-Field is empty using Gitlab-Authentification
Steps to reproduce
- use Mattermost as OAuth2-Server and configure its authentification to Gitlab
- obtain OAuth token object
Observed with Mattermost 3.6.2 / Gitlab 8.17.3
Expected behavior
- the token object contains both filled values: "access_token" and "refresh_token"
Observed behavior
- only "access_token" is filled
- "sometimes" the refresh_token is filled, but I could not figure out under what circumstances it happens
