Maybe this helps: https://github.com/git-ecosystem/git-credential-manager/pull/1062 as mentioned here: https://github.com/git-ecosystem/git-credential-manager/issues/145#issuecomment-1428774678

I thought https://github.com/git-ecosystem/git-credential-manager/issues/1426 already support this. My gitea site works with GCM out of the box without any configuration on windows .

[bohni]

Ah, ok.

I'm running it on a sub path "https://example.com/git" and the URL that opens is https://example.com/login/oauth/authorize?..." - So I had to use the mentioned config... (I'm actual on windows, not Linux)

[ghost]

@bohni Could you show your conig?

[bohni]

My -working - config ist

[credential "https://example.org"]
	useHttpPath = false
	provider = generic
	oauthClientId = e90ee53c-94e2-48ac-9358-a874fb9e0662
	oauthAuthorizeEndpoint = /git/login/oauth/authorize
	oauthTokenEndpoint = /git/login/oauth/access_token

When I remove this section, the URL that opens in the Browser is

https://example.org/login/oauth/authorize?response_type=code&client_id=e90ee53c-94e2-48ac-9358-a874fb9e0662&state=eacb7d86074a4e5397b1855465b78d41&code_challenge_method=S256&code_challenge=r9nb-3HlHYUfMTm2QYItdmXnbO828rRGyF8ktI_w8p4&redirect_uri=http%3a%2f%2f127.0.0.1%3a55150%2f

This URL is missing the required subpath /git

Edit 2024-03-14: I'm running Gitea behind Apache httpd: see Apache HTTPD with a sub-path

03:35:08.057616 ...ricOAuthConfig.cs:38 trace: [TryGet] Invalid OAuth configuration - missing/invalid authorize endpoint:

If your git version is older than 2.41.0, it won't pass the WWW-Authenticate header to the credential helper and therefore won't autodetect Gitea. Either configure endpoints manually or update git executable.
