Apart /home (via autofs), i export /srv to clients. Both, as you can
see, are XFS ACL-enabled filesystem:

 Mar  6 05:09:33 rita kernel: SGI XFS with ACLs, security attributes, no =
debug enabled
 Mar  6 05:09:33 rita kernel: SGI XFS Quota Management subsystem

As requested:

  rita:~# mount
  /dev/sda1 on / type ext3 (rw,noatime,errors=3Dremount-ro)
  proc on /proc type proc (rw)
  sysfs on /sys type sysfs (rw)
  devpts on /dev/pts type devpts (rw,gid=3D5,mode=3D620)
  tmpfs on /dev/shm type tmpfs (rw)
  /dev/sda2 on /usr type ext3 (ro)
  /dev/md2 on /var type xfs (rw)
  /dev/md5 on /home type xfs (rw,nosuid,nodev,usrquota)
  /dev/md4 on /srv type xfs (rw,noexec,nosuid,nodev,grpquota)
  none on /proc/bus/usb type usbfs (rw)
  rita:~# exportfs -v
  /home		mario.ac.concordia-pordenone.it(rw,wdelay,root_squash)
  /home		giovanni.ac.concordia-pordenone.it(rw,wdelay,root_squash)
  /srv		mario.ac.concordia-pordenone.it(rw,wdelay,root_squash)
  /srv		giovanni.ac.concordia-pordenone.it(rw,wdelay,root_squash)

The last...

 rita:~# uname -a
 Linux rita 2.6.15.4 #1 SMP Tue Feb 28 19:16:58 CET 2006 i686 GNU/Linux

I usually set ACL only via windows, but...

 rita:/srv/users/Da Riordinare/VARIE# getfacl ViewReport.pdf
 # file: ViewReport.pdf
 # owner: root
 # group: root
 user::rwx
 group::---
 group:presidenza:rwx
 group:segreteria:rwx
 mask::rwx
 other::---
 rita:/srv/users/Da Riordinare/VARIE# setfacl -m u:gaio:r ViewReport.pdf
 rita:/srv/users/Da Riordinare/VARIE# getfacl ViewReport.pdf
 # file: ViewReport.pdf
 # owner: root
 # group: root
 user::rwx
 user:gaio:r--
 group::---
 group:presidenza:rwx
 group:segreteria:rwx
 mask::rwx
 other::---

yes, it works. ;)


Hope these helps. And many thanks.
