OK, that's certainly the issue here.  Can you please file a bug, so we
can try and handle or at least detect it more clearly at classicupgrade
time?

Well, that doesn't control the samba passdb.tdb record, which is where
the failure is.

That looks like an un-initialised value to me...

old samba3 server:
LANG="de_DE"
LC_ALL="de_DE"

smb.conf:
display charset = ISO8859-1
unix charset = ISO8859-1
I remember the reason for this was a software that couldn't handle
UTF-8 (which is fixed meanwhile) - and I know that we need to convert
the whole content of the filesystem when we migrate...

old samba3 server:
add machine script = /usr/sbin/useradd -c Machine -d /dev/null -g 1000
-s /bin/false %u

all machine accounts are added via this entry - so I thought they are the same.

What was your 'unix charset' (we may need to add a conversion here, as
we assume UTF8 at the ldb layer).

Can you give me some more detail about what is wrong here?  We generally
do want to convert any valid samba3 account.

Exactly what command did you run? 

We should upgrade a ROLE_DOMAIN_PDC into an 'server role = active
directory domain controller'.  Are you sure you are using the smb.conf
produced by the upgrade?

[Samba] samba3 to samba4 // logon hours // server role secrets.tdb, secrets.ldb

2012-10-15 Thread Johannes Paechnatz 
Hello.

I tried the migration from samba3 domain master (pdc) to a samba4.

samba4 -V:
Version 4.1.0pre1-GIT-2c3a808

I used the wiki entry about samba3 migration as a guide, copied over
the data etc. but I have some questions left.

fyi - samba3 tdbsam backend. I removed/edited serveral user accounts
with Umlauts in Fullname/Displayname. (tdbdump/text editor/tdbrestore)
until all user accounts got migrated.

1. machine accounts: some machine accounts don't have Logon hours
FF what seem to be a problem.
Could I manually change fields (which fields?) in the tdbsam dump? I
tried pdbedit  -Z of the specific account, but that seems to change it
to an epoch style timestamp and migration fails again - so I removed
them in the tdbsam dump to get the migration working, after that
additional steps all user and machine accounts get migrated.

2. The server role of samba3 is ROLE_DOMAIN_PDC after migration the
samba4 server is stand alone and starting of smbd works without error.
BUT if I change the server role to active directory domain controller
and try samba instead of smbd, I get an error: Failed to find record
for MYDOMAIN-HERE in /var/lib/samba/private/secrets.ldb: No such
object: Have you provisioned the MYDOMAIN-HERE domain? Provisioning an
new and empty ADS from scratch does work - but I need the migration
;-)
I tried to modify the secrets.tdb before I start the classicupgrade
without success.

This is a show-stopper ;-)

Do you could provide me a hint / solution to this?

Thanks.
