You can extend the schema, Samba even supplies a script to turn
openldap schemas to Active directory ldifs and it has the imaginative
name of 'oLschema2ldif'

We have a wikipage for dovecot:

https://wiki.samba.org/index.php/Authenticating_Dovecot_against_Active_Directory

Try an internet search for 'nextcloud active directory' or 'nextcloud
kerberos'

No you cannot use windows tools, but you could write your own scripts,
or use something like Linux Account Manager (LAM)

You can use openldap as an AD proxy, (yes, we also have a wiki page for
this:  https://wiki.samba.org/index.php/OpenLDAP_as_proxy_to_AD )
But you probably don't need to do this ;-)
