Questions about ACLs

I did a migration on my test system with "--use-xattrs=yes" (latest git 
version). I can add additional users/groups to a file or directory. The 
changes are also stored, if I recheck this later. But where it is stored? 
getfacl doesn't show it to me:

# getfacl bla
# file: bla
# owner: 1061
# group: 1031

The "Testing your filesystem" section from the HowTo works fine. Also the ext4 
filesystem is mounted with user_xattr:
/dev/sda1 on / type ext4 (rw,user_xattr)

The kernel on my Scienetific Linux 6 (RHEL6 clone) is also compiled with xattrs:

Where are the additional ACLs stored and why not in the filesystem here? Did I 
miss something?

And one more question about ACLs:
In my s3 live system, my user/groups are stored in LDAP and I see the 
owner/group of file trough nss_ldap on linux. In my s4 test environment, now 
all files show only the uid/gid on files/directories. Can I get the 
user-/groupnames back by letting nss_ldap connect to the samba LDAP?
