Updating an Ubuntu installation from launchpad works out of the box. When updating a pip installation, please note that a new database table was added.
OTP system migration
privacyIDEA now helps you to migrate an old 3rd party installation to privacyIDEA. To do so the new RADIUS passthru policy was added. privacyIDEA can pass all authentication requests for users without a token to the defined RADIUS server. This way you can migrate tokens smoothly and run your old system and your new privacyIDEA side by side until you have removed all old tokens or moved all users and tokens to privacyIDEA.
The LDAP received some nice improvements. It can now handle special characters like é and ß in the username and the password reliably. With Active Directory in Windows 2012 you can now use the objectGUID as the UID in the LDAP resolver.
We now use paged searched when retrieving user lists. This way you can get really all users in the LDAP directory.
