Hello everyone,

In Sourcetree, I'm trying to add an account at the Remote repositories. In the window that says 'Edit Hosting Account', I choose GitLab as Hosting Service and HTTPS. 

In LrzGitlab, I create a personal access token which I use as password in the 'Sourcetree personal access token request' window that pops up, along with my username. It then always says 'Authentication failed'. 

My coworker always uses GitLab as Hosting Service, even though the PAT was created in LrzGitLab, but that doesn't work for me apparently. I hope someone has experience with LrzGitLab or that sort of problem in general. Any idea would be much appreciated.

Hi @smn_ksng

Welcome to the Atlassian community!

LrzGitLab is a self-hosted GitLab, so choosing plain GitLab as a hosting service points to SourceTree on gitlab.com. That will always fail with a token from another server. I would switch to GitLab CE or GitLab EE in the hosting service dropdown and set the host URL to your LRZ instance.

Two more things I would verify:

  • The PAT needs the api scope, not just read_repository
  • Username must be your GitLab username, not your email or TUM/LRZ ID

Cheers, Martin
