Hi,
Linux clients and the domain controller are all Debian Wheezy.
(on the client)
$ pulseaudio --version
pulseaudio 2.0
$mount
...
//fichdc/uhomes/teachers/pellegrb on /home/teachers/pellegrb type cifs
(rw,relatime,sec=ntlm,unc=\\fichdc\uhomes,username=pellegrb,uid=3000137,noforceuid,gid=3000038,noforcegid,addr=172.16.200.20,unix,posixpaths,serverino,acl,noperm,rsize=1048576,wsize=65536,actimeo=1
(on the server, samba4 compiled from source)
# samba-tool --version
4.1.4
I have made an ugly workaround with pam_exec that remove the ACLs at
user login :
home=`eval echo ~$PAM_USER`
mkdir -p $home/.pulse
setfacl -b $home/.pulse
chmod 0700 $home/.pulse
The way the user can launch PulseAudio.
Thank you very much for your help !
Baptiste.
