Clone of a organization's GitHub repository fails:

Problem

User tries to clone the organization's repository in his IDE UI via Git > Clone.. > GitHub option. During authentication GitHub webpage opens and shows: Authentication Succeeded, but when the user returns to the IDE - there is a message: Authentication Failed.

The IDE log has the following records:

INFO - #git4idea.commands.GitHandler - Authentication request was cancelled
INFO - #git4idea.commands.GitHandler - Authentication request was cancelled
INFO - #git4idea.commands.GitHandler - remote: Repository not found.
INFO - #git4idea.commands.GitHandler - fatal: Authentication failed for 'https://github.com/one-thd/pec-orchestrator/'

Cause

When using OAuth authentication method to authenticate to GitHub from the IDE, it is required to:

• Provide permissions to the OAuth app to have access to the user's account (done by user)
• Provide permissions to the OAuth app to have access to the organizaton's data (done by organization administrator)

Resolution

• Ask the organization administrator to allow the IDE OAuth app to access the organization's repositories
• In case an organization administrator denies access to the OAuth app, it is possible to try with the personal access token instead: https://www.jetbrains.com/help/idea/github.html#-hbpghs_26
