Nextcloud join script fails on a fresh install of ucs 5

Hi Sambila,

making the domain trusted worked just fine!
…but still does not make the join script running…

it fails like in this post with the same message:

There are no commands defined in the “saml:config” namespace.

Could not create LDAP Config at Nextcloud
EXITCODE=1
bedb271a-ac97-4563-b89a-97832d64c928
univention-join-hooks: looking for hook type “join/post-joinscripts”

any idea?
i tried removing some nextcloud saml service entries, but these are recreated again, until the script fails.
How to figure out, what it is exactly that fails?

Thanks!
