The host name in the domain setup can be max. 13 digits. Underscores are also not accepted.
This information should be added in the manuals, please.

I guess you mean 13 characters that must be either characters [a-z] or digits [0-9]. Right?

I guess it don't matter, just 13 positions max could be used for the host name in the domain setup.

After discussion in the dev team it's:

* Maximum length of 13 characters

* Allowed characters: alpha numeric [a-z0-9]

* Start and end only alpha numeric characters. In between a hyphen (-) is allowed.

The manual now has a section about hostname naming conventions: https://docs.software-univention.de/manual/5.0/en/installation.html#naming-convention-for-hostnames
