From edfd148ea6d3450f2ff4d26cb6fefbac21cbc9a1 Mon Sep 17 00:00:00 2001 From: data Date: Sun, 8 Feb 2026 06:23:20 +0100 Subject: [PATCH] Add plain text password storage option for CardDAV (Nextcloud support) - Add storePlainTextPassword setting in SettingsCore and SettingsModel - Add UI switch in CarddavSettingsLayout.qml to toggle plain text password - Allow multiple CardDAV accounts by setting showAddButton = true - Add CardDAV troubleshooting documentation in README.md This fixes CardDAV synchronization with Nextcloud/WebDAV servers that use HTTP Basic Authentication, which requires plain text passwords instead of the default HA1 hash storage.

This works for SIP authentication (Digest Auth) but **does not work for HTTP Basic Authentication** which Nextcloud/WebDAV servers typically require. + +When `store_ha1_passwd=1` (default), the password is hashed immediately after first use and the plain text password is deleted. On subsequent requests, the HTTP client cannot authenticate because it only has the hash, not the password needed for HTTP Basic Auth. + +#### The Solution + +Enable plain text password storage in the CardDAV settings: + +1. Open Linphone Settings → Contacts → CardDAV +2. Enable **"Store plain text password (for HTTP Basic Auth)"** + - German: "Passwort im Klartext speichern (für HTTP Basic Auth)" + +Alternatively, you can manually edit the `linphonerc` config file: + +```ini +[sip] +store_ha1_passwd=0 +``` + +**Security Note:** When this option is enabled, passwords are stored in plain text in the config file instead of being hashed. This is necessary for CardDAV/WebDAV services that use HTTP Basic Authentication. + +#### Additional Troubleshooting + +* If you see "SSL handshake failed: No CA Chain is set", ensure the `root_ca` path in your linphonerc points to a valid certificate file with an absolute path. + +* If credentials are not persisting after restart, make sure you have enabled plain text password storage as described above. + +* Multiple CardDAV accounts are now supported. You can add multiple CardDAV address books in the settings. + ## Specific instructions for the Mac Os X platform
