Description:
KDE Telepathy authentication handler
This package provides a Telepathy handler for the ServerAuthentication and ServerTLSConnection Telepathy channel types, which means that it provides passwords to connection managers (and stores them using KWallet) and also handles SSL certificate errors in encrypted IM connections. . This package is not meant to be used standalone. It is recommended to install the kde-telepathy metapackage instead.
