If the admin chooses to not enter a admin password in tl-setup, as of bug 7528, the tlwebadm-service will not be started. This is expected behavior but in the summary in the last step of tl-setup the text states:
> ThinLinc has been setup
> The ThinLinc Web Administration is available at
> https://localhost:1010, and the configuration files are located in [...]
This is not true in this case since tlwebadm was never started. This could lead to confusion.
Looking in the log on the other hand it is clear that tlwebadm is not started:
> 2021-05-27 09:23:51,190: Starting service 'vsmagent'...
> 2021-05-27 09:23:51,593: No web admin password given. Skipping tlwebadm.
> 2021-05-27 09:23:51,593: Starting service 'vsmserver'...
To clarify this is not a consequence of bug 7528, tlwebadm has never been able to start without password. So the text has always been misleading in this case.
