Problems with ACL's?

[Charles Tryon]

I've been away from this list for a while so it's altogether possible that
I've missed something in the discussions here, but running into a problem
with ACL support that I haven't been able to sort out.

I'm building on two different bases: One is a FC16 based server which was
running very well as a Samba4 server right up through the 4.0.0 release.
 The other is a CentOS 6.3 server installed as a "minimal server"
configuration, which means it's missing a LOT of the extra packages that
you'd usually see on a vanilla system.  I was thinking that the problem was
some missing development library, but I have since found that BOTH systems
are exhibiting the same error.

I have gone through the HOWTO again to make sure I haven't missed any setup
steps.  In particular, I've run through the OS requirements page for
required RPM packages, and the xattr test steps.  I'm made sure that my
/etc/fstab lines for the various ext4 physical file systems have the
"user_xattr,acl,barrier=1" attributes.  The setgattr and getfattr tests
return exactly the results that are shown in the Wiki page.

touch test.txt
setfattr -n user.test -v test test.txt
setfattr -n security.test -v test2 test.txt
getfattr -d test.txt
getfattr -n security.test -d test.txt

touch test3.txt
setfacl -m g:adm:rwx test3.txt
getfacl test3.txt

HOWEVER, on both the system which was running fine before, and on the new
system, I get the exactly the same response when I try to run the
provisioning step:

ldb: module schema_load initialization failed : No such object
ldb: module rootdse initialization failed : No such object
ldb: module samba_dsdb initialization failed : No such object
ldb: Unable to load modules for /usr/local/samba/private/sam.ldb: (null)
samdb_connect failed
VFS connect failed!

? uname -a

Any ideas where I should be looking?
