Nextcloud: Admin account, No privileges

NethServer Version: 7.6
Module: Nextcloud
Database: LDAP

I’ve recently completely reinstalled nethserver (due to some issues: Nethserver Vhost)

Now I have installed NextCloud. Added my domain to trusted.
But when I try to login using the default admin-account for which I set a password using Nethserver, it seems to be a simple user. I can’t access configuration except for “Personal”. No appstore or theming in sight.

You need to use the Nextcloud admin account, also named admin. The default password (which you should change immediately) is Nethesis,1234

I indeed found it later
Where can I vote for the removal or renaming of either user? or a big red span saying “This is not the same admin as nextcloud admin”?
