samba - Sep 2018 - 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*
*ERROR(<type 'exceptions.ValueError'>): uncaught exception - zero
length
field name in format*
*  File
"/usr/local/samba/lib64/python2.6/site-packages/samba/netcmd/__init__.py",
line 177, in _run*
*    return self.run(*args, **kwargs)*
*  File
"/usr/local/samba/lib64/python2.6/site-packages/samba/netcmd/domain.py",
line 1681, in run*
*    useeadb=eadb, dns_backend=dns_backend, use_ntvfs=use_ntvfs)*
*  File
"/usr/local/samba/lib64/python2.6/site-packages/samba/upgrade.py",
line 845, in upgrade_from_samba3*
*    result.names.domaindn, result.lp, use_ntvfs)*
*  File
"/usr/local/samba/lib64/python2.6/site-packages/samba/provision/__init__.py",
line 1693, in setsysvolacl*
*    userdn = '<SID={}-{}>'.format(domainsid,
security.DOMAIN_RID_ADMINISTRATOR)*

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.

Thanks!

I ran the same thing with 4.8.5 and it work without any issues:

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

The answer is staring you in the face ;-)

python2.6 isn't new enough for:

'<SID={}-{}>'.format(domainsid,security.DOMAIN_RID_ADMINISTRATOR)

It would have to be:

'<SID={0}-{1}>'.format(domainsid,security.DOMAIN_RID_ADMINISTRATOR)

Or:

'<SID=%s-%s>' % (domainsid,security.DOMAIN_RID_ADMINISTRATOR)

What is your OS ?

Rowland

This code did indeed change for Samba 4.9.  What python version are you
using?

Thanks,

Andrew Bartlett
