Little stumbling blocks at the nextcloud settings
The uid needs to be in lowercase
to get the certificate, and just copy the certificate only.

If the nextcloud app is installed on an other server you need this fqdn for the identity provider here.
Please have in mind, that checkmark
Allow transmissions of ldap attributes to the service provider in the Extendes Settings category has to be set, even if you define no additional ldap attributes, that have to be transmitted. UCS transfers the
uid attribute back to the Nextcloud App every single login, that’s why, the checkmark is mandatory.
