    Yes, you could download nextcloud desktop version ( link), and use like other cloud storage services.

  • Q: How to share files? You could click file and there will be share option, possible options are

Bookstack

  • Q: Can I share book/page to certain person?
    A: No, you cannot, since bookstack's design philosophy is public wiki inside group. So you could only make the book visible to group but not certain person. If you would like a private page, you could alternatively use nextcloud.

  • Q: How the groups are allocated now?
    A: There are four groups currently

    • Admin: used for management.
    • Staff: wimis, professors, etc... are included in this group.
      User in this group could view/edit other people's book
    • Guest: students, external collobarative phd/prof etc.
      User in this group could only personal book.
    • Public: anoymoous people, i.e. people without login.

Mattermost

Gitlab

Keycloak

  • Q: Can I change my username?
    A: No, you could not change your username, that's used for identification by authentification in different applications.
  • Q: What's the relationship of keycloak and LDAP? LDAP and Keycloak are "user federation", keycloak suppiles OIDC and SMAL authentification, and LDAP supplies LDAP authentification. They coordinate together to supply user authentification service.
  • Q: Can I change my EMail?
    Yes, and it's recommended to use TU's EMail.
  • Q: Why in Keycloak shows that my password Created January 1, 1970 at 12:59 AM.?
    This is a known issue since user-fedoration with LDAP.
  • Q: Can I change password directly in other webservices like mattermost?
    No, You could only change credentials in Keycloak.
  • Q: Can new user directly register account?
    No. Future we may have a invitation based solution.
  • Q: What will be different by different lab position?
    This relates to permission and visiability, generally users like 'guest', 'student' will have only limited permissions in different services.

Notice:

  • It's recommended to add SSH key to use gitlab asap.
  • You could only change your profile like name password under keycloak
  • Services under the name xxx back-up is the last day's mirror and only be used when emergent usage like service is down.
  • Nextcloud:
    • there is a group called "everyone", any people is defautly in this group, you could place any files that you wanna to share public
    • Be careful for online/offline editing office(docx, xlsx, pptx etc) files, You could only cooperate(multiple users edit one file ) online. And remember to check if your editing is synced back properly or not.
  • Bookstack:
    • phd and phd+ has permission to read/write any books/pages/..., while guest only read/write their own books.
