(Azure DevOps only) What format is your remote URL?

None

Can you access the remote repository directly in the browser?

Yes, I can access the repository

Expected behavior

Login with username of name_company and all subsequent git commands should work.

Actual behavior

Git asks for reauthentication when there is an underscore in the username.

Clear login credentials from Windows Credential Manager
Run git fetch origin
Sign in using login token
Run git fetch origin
Failed - Requests for sign in again

The workaround, i.e. to replace ‘_’ in the username with ‘-‘ works. These steps look like:

Clear login credentials from Windows Credential Manager
Run git fetch origin
Sign in using token
Go into Windows credential manager
Edit creds and replace ‘_’ in the username with ‘-‘
Run git fetch origin
Success – no request for login

Hello! This looks like you're using Enterprise Managed Users with a username in the format user_company.

Does the customer have this setting enabled or not for their enterprise?

Settings > Authentication Security > Single sign-on settings > Automatically redirect users to sign in.

GCM with EMU can have some strange behaviour if this is not enabled.

For additional troubleshooting, they you enable GCM tracing and provide this and we can see what's going on. To enable tracing you can set the GCM_TRACE environment variable to 1.
