This is a Civilized Place for Public Discussion

Please treat this discussion forum with the same respect you would a public park. We, too, are a shared community resource — a place to share skills, knowledge and interests through ongoing conversation.

These are not hard and fast rules, merely aids to the human judgment of our community. Use these guidelines to keep this a clean, well-lighted place for civilized public discourse.

Posting Guidelines

Preferred language is English

The preferred language of is English. This makes it easier for all contributors to understand and help each other. So if you want your topic to be read and solved, use a language that most contributors are comfortable with.

Please be specific

Large open ended questions like “How do I use UCS with a Active Directory?” or “How do I use the mailserver?” are generic, very time consuming to narrow down in a discussion and most often far better answered in the documentation or the likes. The first answer may always be a question for more details. Be specific and ask for example “I set up a mailserver, but my mails are not sent. I already checked Google, but I do not know what logs for what error I should look to.”

Provide relevant details

Often, when someone tries to help, they need more information about the environment, the error in particular or just logfile informations. If you have a problem while logging in to the UMC, do not post: “I have a problem with the UMC! Please help?”. Post your UCS version, the error you are getting and what you did that lead to the error. Bonus points for attaching relevant logfiles from /var/log/univention/ and screenshots of the error message.

How to look up the UCS version?

  1. Login to your UCS system via ssh

  2. If you are on Linux or macOS, simply open a terminal and run ssh root@<IP-of-your-UCS-system>. Enter the root/Administrator password you chose during installation (if you haven’t changed it since then).

  3. If you are on Windows, you need a SSH client first, e.g. Then connect to the IP address of the UCS system with the user ‘root’ and the root/Administrator password you chose during installation (if you haven’t changed it since then).

  4. When you are logged in via SSH, run this command to retrieve all information about the current UCS version and installed apps:
    univention-app info

  5. The output should look similar to this:

    UCS: 4.1-4 errata408
    App Center compatibility: 4
    Installed: dudle=1.1.0-1 nagios=3.4

Be prepared to provide further information upon request.

Describe what you have done so far

Pretty self-explaining. If you provide what you did already, the helping person does not need to suggest this method to you.

Mark topics as [solved]

Every posting has a button to mark the topic as solved:


That attaches the solution directly to the first posting and makes it easier to recognize it for every contributor. Additionally a solved topic is marked in the overview so everyone looking for answers may find it more easily.

Tell others about your solution

If you found a solution by yourself, please tell everyone how you solved the problem instead of a simple “Its OK now, I solved it.” - Nothing is more frustrating, then searching and finding a relevant thread - scrolling through it till the dreaded “solved it” without telling how. Please do not be that person.

Improve the Discussion

Help us make this a great place for discussion by always working to improve the discussion in some way, however small. If you are not sure your post adds to the conversation, think over what you want to say and try again later.

The topics discussed here matter to us, and we want you to act as if they matter to you, too. Be respectful of the topics and the people discussing them, even if you disagree with some of what is being said.

One way to improve the discussion is by discovering ones that are already happening. Please spend some time browsing the topics here before replying or starting your own, and you’ll have a better chance of meeting others who share your interests.

Be Agreeable, Even When You Disagree

You may wish to respond to something by disagreeing with it. That’s fine. But, remember to criticize ideas, not people. Please avoid:

  • Name-calling.
  • Ad hominem attacks.
  • Responding to a post’s tone instead of its actual content.
  • Knee-jerk contradiction.

Instead, provide reasoned counter-arguments that improve the conversation.

Your Participation Counts

The conversations we have here set the tone for everyone. Help us influence the future of this community by choosing to engage in discussions that make this forum an interesting place to be — and avoiding those that do not.

Discourse provides tools that enable the community to collectively identify the best (and worst) contributions: favorites, bookmarks, likes, flags, replies, edits, and so forth. Use these tools to improve your own experience, and everyone else’s, too.

Let’s try to leave our park better than we found it.

If You See a Problem, Flag It

Moderators have special authority; they are responsible for this forum. But so are you. With your help, moderators can be community facilitators, not just janitors or police.

When you see bad behavior, don’t reply. It encourages the bad behavior by acknowledging it, consumes your energy, and wastes everyone’s time. Just flag it. If enough flags accrue, action will be taken, either automatically or by moderator intervention.

In order to maintain our community, moderators reserve the right to remove any content and any user account for any reason at any time - especially if the user or the content is abusive or harassing, either in this or any other community or platform. Moderators do not preview new posts in any way; the moderators and site operators take no responsibility for any content posted by the community.

Always Be Civil

Nothing sabotages a healthy conversation like rudeness:

  • Be civil. Don’t post anything that a reasonable person would consider offensive, abusive, or hate speech.
  • Keep it clean. Don’t post anything obscene or sexually explicit.
  • Respect each other. Don’t harass or grief anyone, impersonate people, or expose their private information.
  • Respect our forum. Don’t post spam or otherwise vandalize the forum.

These are not concrete terms with precise definitions — avoid even the appearance of any of these things. If you’re unsure, ask yourself how you would feel if your post was featured on the front page of the New York Times.

This is a public forum, and search engines index these discussions. Keep the language, links, and images safe for family and friends.

Keep It Tidy

Make the effort to put things in the right place, so that we can spend more time discussing and less cleaning up. So:

  • Don’t start a topic in the wrong category.
  • Don’t cross-post the same thing in multiple topics.
  • Don’t post no-content replies.
  • Don’t divert a topic by changing it midstream.
  • Don’t sign your posts — every post has your profile information attached to it.

Rather than posting “+1” or “Agreed”, use the Like button. Rather than taking an existing topic in a radically different direction, use Reply as a Linked Topic.

Post Only Your Own Stuff

You may not post anything digital that belongs to someone else without permission. You may not post descriptions of, links to, or methods for stealing someone’s intellectual property (software, video, audio, images), or for breaking any other law.
