Yes, but a beta tester also says that: "runtime dependencies: KDE 4 libs (kdelibs5), QCA2 and the openssl plugin (libqca2?, libqca2-ossl?), libXScrnSaver (libxss?), the Oxygen icon theme." > Did I get > your correct, that it works, if you install "qca-ossl"? Yes, just after installing qca-ossl authentication starts to work right. > In fact I would > expect the package called "qca2-ossl", but ... I agree... strange numbering. Maybe because qca and qca2 are both in use by different programs while only qca-ossl 2 is in use? It bumped directly from 0.1 to 2.0 beta... http://koji.fedoraproject.org/koji/packageinfo?packageID=5203 https://admin.fedoraproject.org/pkgdb/packages/name/qca2 https://admin.fedoraproject.org/pkgdb/packages/name/qca-ossl Thanks again, Diego
