Yes netlogon was on btrfs.

I beleive I followed the wiki properly for provisioning the dc then for
the shares.

I started over by redoing provision and some test mounted shares and
minimal changes
to the smb.conf that was generated,
    /usr/bin/samba-tool domain provision --use-rfc2307 --interactive

I did something different and put two mounts under sysvol,
and yes when I ran samba-tool ntacl sysvolreset
it recursively set acl on the under mounted file sytems...
and I could see them,
but I did not think we should be sharing under sysvol ?

And the example in the root file system, btrfs, but not under
sysvol has the same old problem, no access permission to change

I may be giving a wrong lead.. but doing ls -al, it seems that the unix
and files are not set with an acl/xattr unless I put them under sysvol
and run samba-tool ntacl sysvolreset

What do you want me to try next?

To show mounts and file system,

df -h / /var/lib/samba/sysvol/testext3 /var/lib/samba/sysvol/testbtrfs
