[Samba] CentOS 6.4 Sernet Samba 4.1.3 ad -> no ACL Filesystem ?

[Marc]

I'm running into trouble while setting up samba4 on centos 6.4
see

i read somewhere that it checks the filesystem for acl support
so i remount my filesystems with acl:
# mount |grep acl
/dev/mapper/vg_testsystem-lv_root on / type ext4 (rw,acl)
/dev/sda1 on /boot type ext4 (rw,acl)

but no luck
i read somewhere that this happens if samba is compiled while missing 
acl librarys. so i looked into sernet-samba-4.1.spec

# fgrep -i BuildRequires sernet-samba-4.1.spec
BuildRequires:  tar gzip bzip2
BuildRequires:  perl
BuildRequires:  python-devel >= 2.5, python-devel < 3.0
BuildRequires:	make gcc util-linux lsof file findutils gawk
BuildRequires:	cups-devel readline-devel openssl-devel ncurses-devel

BuildRequires:	libnscd-devel
BuildRequires:	libcom_err
BuildRequires:	libiniparser-devel
BuildRequires:	libgnutls-devel
BuildRequires:	gnutls-devel

all are installed. beside some names are confuseing me
(like libgnutls-devel, there is no libgnutls in Base Repo)
i rebooted the machine - but still no luck.

may someone point me into the right direction?
thanks
