[Samba] I can't join to an existing domain (yet)

[Denis Morejon Lopez]

People:

I have not solved my problem. I have only one DC with Zentyal 3.4 and I 
want to change it by samba 4.1.16. That's why if I can't join the samba 
to the existing domain I would not do anything else.

The samba server error is this:
(Command from samba)
samba-tool domain join dtcf.etecsa.cu DC -U administrator 
--realm=DTCF.ETECSA.CU --dns-backend=BIND9_DLZ

I can see this entry in the Zentyal server
(Command from Zentyal)
  ldbsearch -H /var/lib/samba/private/sam.ldb

But I can't delete it
(Command from Zentyal)
ldbdel -H /var/lib/samba/private/sam.ldb 
'CN=PC00017104336\0ACNF:5798425a-db30-4f39-98ed-6e8aa15c34b5,CN=PC009375,CN=Computers,DC=dtcf,DC=etecsa,DC=cu'

(Response)
delete of 
'CN=PC00017104336\0ACNF:5798425a-db30-4f39-98ed-6e8aa15c34b5,CN=PC009375,CN=Computers,DC=dtcf,DC=etecsa,DC=cu'

entry does not exist!

So, I tried all ldbdel options looking for one that forces the deletion. 
And I found "--relax"
(Command from Zentyal)
  ldbdel --relax -H /var/lib/samba/private/sam.ldb 
'CN=PC00017104336\0ACNF:5798425a-db30-4f39-98ed-6e8aa15c34b5,CN=PC009375,CN=Computers,DC=dtcf,DC=etecsa,DC=cu'

(Response)
===============================================================
INTERNAL ERROR: Signal 11 in pid 26667 (4.1.5-Zentyal)
Please read the Trouble-Shooting section of the Samba HOWTO
===============================================================
PANIC: internal error
Aborted (core dumped)

I repeated the operation stopping samba daemon but the I got the same 
response.

Event, I could delete other entries with the pattern  '(CN=*CNF:*)' as 
Rowland taught me. But only 10 are not erasable like the one I write here.

Is it imposible to delete these bad entries ??
