Hi Currently, LibreOffice have it's own way to store password and secure them with a master password. But desktop environment on Linux and also Windows and Mac have it's own system. LibreOffice should use when it's available, the system password manager.
For example a sample program to use it on windows : http://stackoverflow.com/questions/9221245/how-do-i-store-and-retrieve-credentials-from-the-windows-vault-credential-manage
I agree with Arnaud. Although there is a bunch of password managers, LibreOffice should at least support the main ones: - Credential Manager (Windows Vault) on Windows; - Keychain on OS X; - kWallet on KDE - Gnome Keyring for Gnome (do not use Seahorse since it is just a front-end for GPG and SSH). - Keepass which is a multiplatform and FOSS. Regards,
This feature request is obviously for remote file system accesses like WebDAV, CMIS, SMB, etc. not to open a document which is password protected.
