[Samba] classicupgrade fails on rc6, worked on rc5

[Thomas Simmons]

Hello,

I get the following error when performing a classicupgrade on rc6. This
does not occur with rc4 or rc5. The command I am using is:

samba-tool domain classicupgrade \
--dbdir=/root/import/var/lib/samba  --use-xattrs=yes \
--realm=internal.testdom.com /root/import/etc/samba/smb.conf
