setup_ldb howto? (was: Re: Help using secretsdb_setup_dns like approach to export keytab for service account)

Hi,

Maybe a subject better describing the problem.
I've done small modifications to the code (class attached), replacing
setup_ldb with setup_add_ldif, the error becomes:
ERROR(ldb): uncaught exception - Failed to update keytab from entry
samAccountName=www,CN=Principals in
/usr/local/samba/private/secrets.ldb: Failed to add enctype 1 entry for
www at KZSDABAS.HU(kvno 1) to keytab: No such file or directory

  File
"/usr/local/samba/lib/python2.6/site-packages/samba/netcmd/__init__.py",
line 167, in _run
    return self.run(*args, **kwargs)
  File
"/usr/local/samba/lib/python2.6/site-packages/samba/netcmd/spn.py", line
275, in run
    setup_add_ldif(ldb=secretsdb, ldif_path=fpath[1], subst_vars=None)
  File
"/usr/local/samba/lib/python2.6/site-packages/samba/provision/__init__.py",
line 488, in setup_add_ldif
    ldb.add_ldif(data, controls)
  File "/usr/local/samba/lib/python2.6/site-packages/samba/__init__.py",
line 221, in add_ldif
    self.add(msg, controls)
A transaction is still active in ldb context [0x1fc1930] on
/usr/local/samba/private/secrets.ldb

Thanks for any idea!

Cheers
