[Samba] Classicupgrade Errors on password_hash.c:2237

[Mario Codeniera]

Hi,

I am stuck on upgrading from samba3 upgrade to samba4 on Centos 7.
Previously working on Centos 6.x, based on testing before around 2013 or
maybe I missed something.

I don't have any idea what does it mean nor what causing the issues using
Samba 4.2.2:

I issue this command /usr/local/samba/bin/samba-tool domain classicupgrade
--dbdir=/upgrade_to_samba4/migrationDC1/tdbfiles/ --use-xattrs=yes
 --realm=lumad.sandbox.local --dns-backend=SAMBA_INTERNAL
 /upgrade_to_samba4/migrationDC1/smb.conf

I thought it was xattr <https://wiki.samba.org/index.php/OS_Requirements>issue
based on xfs filesystem but same issue and I was wrong.

Hope can someone enlighten me or have encountered the same problems.

Regards,
Mario
