RN 102 / OS 6.4.1: Unable to access $user_home whilst other shares are working

Hey there,

Win 8.1 pro - Samba

setting aside that my RN 102 is extremely slow after updating to 6.4.1, I am unable to access my home folder now ... 

The data is still there (I can access the system via the web frontend and ssh), and SMB is enabled on the "Home Folders". I can see the home folder, if I enter the \\ip.address.of.share\ ; however, I am not able to mount it. Strange enough, I am able to mount the other shares that are not $username but "manually defined" ones without any problem.

Windows complains either about an incorrect password or that the share is already mounted. Using cmd -> net use I sometimes (not always) see a connection to \\ip.address.of.share\IPC$ WITHOUT being mapped to a drive letter.

tail -f to /var/log/samba/log.smb reveals that there is no samba authentication activity while trying to mount $home.

I am a bit disappointed - help would be highly appreciated

Thanks a lot

CW
