Adding Samba4 DC to existing Samba4 Domain

[fishknuckles]

I'm having issues joining a new samba4 DC (alpha20) to an existing samba4 DC
(alpha12).

I basically haven't gotten anywhere.  The install is complete on the new
box, and Krb works fine.  

[root at pdc01 samba]# kinit -V bob
Password for bob at DOMAIN.FOO.COM: 
Authenticated to Kerberos v5

But when I run the samba-tool domain join, I get the following:


[root at pdc01 samba]# /usr/local/samba/bin/samba-tool domain join
domain.foo.com DC -Ubob --realm=domain.foo.com
Finding a writeable DC for domain 'domain.foo.com'
Found DC pdc.domain.foo.com
Password for [FOO\bob]:
workgroup is FOO
realm is domain.foo.com

    return all([is_valid_netbios_char(x) for x in name])

I'm assuming all the python errors are a result of the failure to join the
domain, and not the actual root-cause.  Are there any logs I can look at
that would maybe give me some insight here?  I tried just creating a basic
smb.conf to specify a log file, but that doesn't seem to work.  Also, the
existing PDC doesn't really show any useful errors in its own logs.  It
doesn't seem like I have much to go on.

I'm doing this as part of a migration from old hardware to new hardware.  It
seems like the best way to accomplish this is to join the new box to the
existing domain as a DC, let the databases sync up, and then promote the new
DC to be the PDC.  If there's a better way to accomplish this, please let me
know.

Thank you.
