Afs on Manjaro - cannot start the service

I am trying to get access to afs on Manjaro, but I am unable to start the openafs-client.

I get the following error:
× openafs-client.service - OpenAFS Client Service
Loaded: loaded (/usr/lib/systemd/system/openafs-client.service; disabled; vendor preset: disabled)

The steps that I have taken are:
sudo pacman -S krb5 lib32-krb5 linux513-headers
yay -S openafs openafs-modules-dkms

echo “cern.ch” | sudo tee /etc/openafs/ThisCell

And finally configuring /etc/krb5.conf as outlined here: https://akorneev.web.cern.ch/howto/openafs.txt

I can successfully do kinit.

aklog will not work, since openafs is not running.

Many thanks in advance for any help or suggestions!
