[Pkg-samba-maint] Bug#800003: samba-common-bin: samba-tool classic update w/LDAP - parsing error

[Peter Tuharsky]

Package: samba-common-bin
Version: 2:4.1.17+dfsg-2
Severity: important
Tags: upstream patch

Dear Maintainer,

I have encountered a problem with classicupdate with previous LDAP backend.
The process goes normal, occasional "group already exists" etc.

But it ends up with an error:

ERROR(<type 'exceptions.ValueError'>): uncaught exception - unable to
parse dn string
  File "/usr/lib/python2.7/dist-packages/samba/netcmd/__init__.py", line
175, in _run
    return self.run(*args, **kwargs)
  File "/usr/lib/python2.7/dist-packages/samba/netcmd/domain.py", line
1321, in run
    useeadb=eadb, dns_backend=dns_backend, use_ntvfs=use_ntvfs)
  File "/usr/lib/python2.7/dist-packages/samba/upgrade.py", line 903, in
upgrade_from_samba3
    add_group_from_mapping_entry(result.samdb, g, logger)
  File "/usr/lib/python2.7/dist-packages/samba/upgrade.py", line 274, in
add_group_from_mapping_entry
    m.dn = ldb.Dn(samdb, "CN=%s,CN=Users,%s" % (groupmap.nt_name,
samdb.get_default_basedn()))


I have consulted the error in Samba mailing list (23.9.2015 10:42).
Andrew Bartlett has proposed a patch (24.9.2015 at 9:57).
I asked for help (documentation), since I have no experience
with patching the distributional Samba, therefore I'm not sure
that I will do that correctly, thus unable to guarantee proper patch
testing.
L.P.H. van Belle (24.9.2015 12:49) suggested me to ask the package maintainer.

So I'm asking here. Please, could You apply the Andrew's patch and send me
the .deb so that I could test the patch? It could help correct the bug in
upstream.

Sincerely,
Peter
