Expected behavior

Problem:
Our mobile application has multiple dependencies hosted within the same Azure DevOps organization. When resolving these dependencies, we encounter the following issues:

Multiple authentication popups - A separate authentication dialog appears for each dependency, rather than authenticating once for the entire organization.

GCM freezes on dismissal - If any popup is closed without completing authentication, Git Credential Manager (GCM) hangs indefinitely. Multiple git-credential-manager processes accumulate in Activity Monitor and do not terminate.

Root Cause:
This behavior started after switching to azreposCredentialType = oauth. Previously, credentials were stored per organization in Keychain using the format git://{org}@dev.azure.com/{org}, which allowed a single authentication to cover all dependencies within that organization.

Actual behavior

• Parallel authentications for repos within Azure DevOps organization should be grouped internally (gcm) and lead to a single authentication user prompt.
• Incase of failure to authenticate exit with non zero exit code.

Start by reviewing the attached gitconfig-redacted.txt, gcm-trace-redacted.log, and gcm-git-redacted.log to trace concurrent Azure DevOps OAuth requests and dismissal behavior. Done means requests for repositories in one organization share a single authentication prompt, and failed or dismissed authentication exits with a non-zero status without leaving GCM processes running.
