Cloned from: https://pagure.io/freeipa/issue/9514

we default the option `netbios_name` to None in `/usr/libexec/ipa/oddjob/org.freeipa.server.config-enable-sid`  and do not get it defaulted to a value we generate if it is None. A workaround would be to pass the netbios name explicitly to the tool and a fix is to use `make_netbios_name` out of the realm if not passed:
```
# ipa -e in_server=True console
(Custom IPA interactive Python console)
    api: IPA API object
    pp: pretty printer
>>> from ipaserver.install.adtrustinstance import make_netbios_name
>>> make_netbios_name(api.env.realm)
'EXAMPLE'
```
