Before connecting a contacts application or CardDAV sync adapter, open Settings → Security → App & device access, create a LightDrive client password that includes Contacts for that app or device, and copy the value when displayed. Valid choices include Contacts only, Email & contacts, Contacts & calendars, and Email, contacts & calendars. Choose only the services the app needs.
- Address book URL:
https://dav.lightdrive.one/USERNAME/contacts/ - Username: your full
[email protected]address; your bare LightDrive ID is also accepted - Password: a LightDrive client password that includes Contacts
- Connection security: HTTPS with certificate verification enabled
Replace USERNAME with the LightDrive ID exactly as registered. Your main Vault password, Vault app passwords, and Email-only passwords do not authenticate to CardDAV.
The Vault Contacts app creates and edits this address book. LightDrive Email reads it for recipient lookup but does not write contact changes back to it.
