[Samba] Not sure if ACL support compiled in

["Müller, Thorsten"]

Hi all,
I'm running Samba-3.0.0-2 on an RedHat 8 box.
I compiled it on my own with cups and acl support (and some things, too).
My clients are Win2k and WinXP.
The fileserver has a XFS filesystem with ACL support.
I created a test-share:

[test]
        comment = Test
        path = /xfspart/test
        read only = no
        inherit acls = yes

When i create a file from my WinXP Client it works great
And Windows shows me (under Security Tab) that my user has full permissions,
My group and other have read permissions.
When i try to add another user (mi) with read perm i get an "access denied"
error.

Adding this user from the cli with setfacl works fine.
(see output of getfacl)

[root at host test]# getfacl test.txt
# file: test.txt
# owner: thmuelle
# group: Dom"nen-Benutzer
user::rwx
user:mi:rwx
group::r--
mask::rwx
other::r--

But my winXP shows me (in security tab) not this new user mi!

Did i miss something during compiletime?

Here's my output from ldd:

Would be great if anybody might give me a tip?
Can I fix it, without recompile something?
