[Samba] Samba4 winbind and .gvfs share mounting in Nautilus problem

[steve]

Hi everyone

I have S4 with winbind working fine with s3fs. Fine that is only when 
logging in where it auto-mounts my own /home folder.

When I log in, my /home folder is correctly mounted automatically:
gvfs-fuse-daemon on /home/CACTUS/steve/.gvfs type fuse.gvfs-fuse-daemon 
(rw,nosuid,nodev,user=CACTUS\steve2)

When I attempt to access another share by e.g. smb://server/reports (or 
any other share)
The share is _sometimes_ mounted and works _almost_ (*) as expected, but 
normally the process hangs with top showing gvfs taking up the top 10 
slots and consuming 99% CPU.

(*) file locking doesn't work and permissions and ACL's  are not set 
correctly on the mounted share.

What is the correct method for mounting shares from s3fs in Samba4 after 
you have logged in successfully?
Cheers,
Steve
