Nextcloud davfs kerberos

Hello

I have a working setup of Nextcloud (as univention app, v17, UCS 4.4) with SAML/SSO working via browser. I can also access the files via file manager or shell (using Ubuntu) as per standard instructions (https://docs.nextcloud.com/server/17/user_manual/files/access_webdav.html).

Now my question: is it possible to access nextcloud via dafvs2 (i.e. from the shell) without having to give / save the password, i.e. by relying on kerberos? FWIW the ubuntu host I am using as client is setup so that users get a valid kerberos token (from the UCS KDC) upon login.

Thanks in advance for any tip.
