[Message part 1 (text/plain, inline)]

Package: x2goclient Version: 4.0.3.1 Client OS: Windows 8.1 64-bit with all available updates Server OS: Fedora 21 64-bit with most available updates Server krb5 client: samba winbind 4.1.14-1.fc21 x2goagent: 3.5.0.28 x2goserver: 4.0.1.18 x2goserver-extensions: 4.0.1.18 x2goserver-xsession: 4.0.1.18 (with fix for #632 applied) When I attempt to use GSSAPI authentication on Windows, with either x2goclient 4.0.3.1-20141214 or x2goclient 4.0.3.2 development build (2015-01-11 9363860), I see 2 error messages come up when I start a new session on the aforementioned host: Message 1: Connection failed : cp: missing destination file operand after '/home/DEPAULO/mike/.x2go/C-mike-50-1420995172_stDMATE_dp32/krb5cc' Try 'cp --help' for more information Message 2: Connection failed pscp: unable to open /home/mike/.x2go/ssh/key.Hp6896: no such file or directory Message 1 is on top of message 2. If I reconnect to a session, I only receive message #2. Under both versions of x2goclient, the X2go Session appears to start successfully. e.g., I see my mate desktop launch. And I can actually interact with it. However, whenever I connect with 4.0.3.1-20141214, as soon as I dismiss error message #2, x2goclient terminates entirely. On 4.0.3.2, these error messages are harmless (but annoying.) I've attached the log from the 4.0.3.2 development build (2015-01-11 9363860). I've also attached the server's samba configuration.
