[Samba] ACL ignored on cifs mounted share

[Norbert Heinzelmann]

Hello,

I have the problem that the ACLs are ignored when I mount a share via 
cifs. I have an AD with Samba 4.1.6 Ubuntu 14.04 (but I also tried it 
with Gentoo and samba 4.1.14). So I joined a member server like the wiki 
describes. Everything works fine. I can manage the users and permissions 
with the RSAT tools. For the linux side I use rfc2307 and winbind on the 
member. So every user and group has a uid and gid. I can login at the 
member server, but when I try to access a shared folder it failed with 
permission denied. Here is the output, I hope this helps to understand 
the problem:

root at client9:/home/testsamba# mount -vt cifs //server1/studis 
/data/studis -o user=klaus,sec=krb5
mount.cifs kernel mount options: 
ip=192.168.170.1,unc=\\server1\studis,sec=krb5,user=klaus,pass=********
root at client9:/home/testsamba# getfacl /data/studis/

root at client9:/home/testsamba# su klaus
klaus at client9:/home/testsamba$ id
uid=10000(klaus) gid=10000(rt) Gruppen=10000(rt)
klaus at client9:/home/testsamba$ cd /data/studis/
bash: cd: /data/studis/: Keine Berechtigung (permission denied)

I dont understand, why it is not working. My questions are: Should it 
work? Is it a bug or is it a problem in configuration?

Sorry for my bad English


Best regards
