    We are trying to use the OIDC auth plugin to enable login to our Xen Orchestra without local accounts. We registered a client with our identity provider and got a client id, client secret and the auto-discovery url. That we used to configure the plugin. However, if we login we get redirected back from the identity provider to the XO callback url and receive then an "Internal Server Error" The callback URL is as follow: https://xoa.domain.com/signin/oidc/callback?state=STRING&scope=profile+openid&code=STRING&iss=https://identity-provider.url&client_id=XXXXX In the log file we see then the following 4 lines: mrt 25 12:29:25 vm-xoa xo-server[2618522]: Expected values to be strictly equal: mrt 25 12:29:25 vm-xoa xo-server[2618522]: + actual - expected mrt 25 12:29:25 vm-xoa xo-server[2618522]: + 'undefined' mrt 25 12:29:25 vm-xoa xo-server[2618522]: - 'string' If we change both the username field and the scope to email, we get the same Internal Server Error, but with a different single log line: mrt 25 13:18:04 vm-xoa xo-server[2618522]: Cannot read properties of undefined (reading '0') Because we are getting redirected back from our identity provider to Xen Orchestra we guess that the issue is not there. We also get in the browser a SAML response with the userdata. Running a wireshark on the server shows also traffic between Xen Orchestra and the identity provider, but unfortunately we cannot look in the contents of that traffic stream. Setting the log level to debug does unfortunately not produce more (error) output. We are running Xen Orchestra with commit c3dcb and the auth-oidc (v0.4.2) plugin Is there an other way to figure out what is going wrong?

    Version 1.4.0 is released: https://codeberg.org/NiXOA/system/releases/tag/v1.4.0 It includes significant changes and improvements, including: dedicated getting started section, migration to valkey, only needing to clone system, and helper scripts. the xen-orchestra-ce nixpkg now references the libvhdi nixpkg, and the core flake now references and pulls from the xen-orchestra-ce repo as an overlay. System (the user input flake) now uses the Core repo as an overlay, reducing the need to clone both locally AND allowing system to pull new updates and releases from core. XO, and libvhdi as needed. The next goal is: Make an xsconsole-like TUI Automate package updates for libvhdi and xen-orchestra-ce using CI/CD pipelines Submit libvhdi and xen-orchestra-ce as official nixpkgs

    It is in the same place in XO. Network tab of the host. Change the Mode from None to Static (or DHCP). This should get you a pop up to enter the address, netmask, etc.

    @florent Limiting concurrency did not fix my S3 backup problem, but it's working again after updating the build. So I guess it's resolved.

    You should probably be able to fix this issue by installing the ntfs-3g package. As you mentioned you're running it on a Synology, you can do that in DSM by opening Docker -> Container -> Select your container -> Details -> Terminal and enter the below in the console. apk update apk add ntfs-3g Let us know if it helped.

    @olivierlambert Well, for now, I'm mostly playing around with this tech to teach myself about it, gaining experience and coming up with ideas. Maybe someday I'll be able to return some profit with the business I'm building / trying to figure out (hosting game servers). Then I'll sign up for some Pro support - and maybe then we can work on the concept of HA XO I understand what you're saying. I think I can come up with a good enough way of achieving the HA I'm looking for. Anyway, thanks for takning the time to respond. I understand your schedule is busy.

    If you use XOA, I would strongly suggest to open a support ticket. This way, we can investigate properly on your XOA and see what's going on.

    It's important to understand the components you are using, especially on a software that you use without support/training In short: SR: a Storage Repository is access by your host/dom0/XCP-ng, and will be used to store ISOs and/or VM disks. It's running on a relatively old CentOS release (7.x), and will mount with some specific settings BR/remote: a Backup Repository where Xen Orchestra will send the backup of your VMs. Usually, Xen Orchestra runs (in XOA) inside a Debian 11 VM, with default NFS mount options (default: ie from the operating system point of view). It's hard to tell exactly the issue since you are likely using XO from the sources, so a XO that you choose to install on a system where we (aka "XO devs") have precisely 0 control on. Plus the NFS configuration part is also out our scope because it's not running inside our infrastructure too. That's a lot of moving pieces, that's why it's important to understand what you do so we can assist here the most efficient way we can

    There’s usually little to no reasons to expose any mgmt systems to internet in actual production environments. Especially if it’s strictly for internal mgmt purposes. XO is no exception. Not because the system would be unsecure, but you simply want to make any attack surface as small as possible. It’s just a best a practice.

    I think it's "because" we fixed it upstream and then Fedora packaged the fix in their latest update
