I want to integrate the addressbook of an external application (CRM-like) seamlessly into Nextcloud Contacts as ExternalAddressBook like ldap_contacts_backend does.
Are there any more resources I could learn from, besides ldap_contacts_backend?
Hi, in user_oidc, you’ll find an interesting Backend.php. It may provide another example. ldap_user_backend is based on remote calls, with a cache. user_oidc uses a mysql table. Between the two, you should find your way.
