            Bug ID: 354004
           Summary: smb kioslave timeouts looking for kerberos
                    authentication
           Product: kio-extras
           Version: 5.4.2
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: default
          Assignee: plasma-devel at kde.org
          Reporter: adrien.prokopowicz at gmail.com

I am using the smb kioslave (via Dolphin) to browse my school's shared
directories, located on a Windows 2008 Server's Active Directory.

However, it always takes a very long time to connect (> 30 sec) before I can
finally browse it.

After some research (see attached debugging output), it appears that
libsmbclient actively waits for a Kerberos authentication, and then timeouts
before falling back to NTLM.


Reproducible: Always

Steps to Reproduce:
1. Use kioclient5 to connect to a SMB Windows Server 2008 AD Share without
Kerberos
2. Wait a long time.



I am running an up-to-date archlinux using Plasma and kioclient 5.4.2.
This problem occurs on every version of kio-extras I have tested so far (even
from the 4.x branch), all with a fresh install of any distribution.

However, the problem only appears when using the smb kioslave. It works
correctly using smbclient directly. My classmates using KDE also have this
problem, but the others (using Windows, Mac OSX, or GNOME-based linux desktops)
do not.
