[Samba] ClassicUpgrade: ERROR(<type 'exceptions.ValueError'>): uncaught exception - zero length field name in format

Hi All,

Attempting to do a classicupgrade and getting this error:

*Adding groups*
*Importing groups*
*Committing 'add groups' transaction to disk*
*Adding users*
*Importing users*
*Adding users to groups*
*Committing 'add users to groups' transaction to disk*

line 1693, in setsysvolacl*
*    userdn = '<SID={}-{}>'.format(domainsid,

I don't recall seeing this during my testing with 4.8.X, but I decided to
do my actual upgrade with 4.9. But I'm also not sure it isn't just related
to a new account or setting we made between testing and now.

Any help would be appreciated.
