[Samba] Problems with samba 4.5.5

[Marcio Demetrio Bacci]

Hi,

My Domain Controllers are using Samba 4.2.1 on Debian 7

I have upgraded my Secondary DC of the 4.2.1 to 4.5.5 version, as the
follow:

1) cd /root
2) wget -c https://download.samba.org/pub/samba/samba-4.5.5.tar.gz
3) tar -xzvf samba-4.5.5.tar.gz
4) cd samba-4.5.5
5) ./configure --prefix=/opt/samba --enable-debug --enable-selftest
6) make

7) /etc/init.d/samba stop
8) /etc/init.d/ntp stop

9) make install

At the end, the *samba-tool dbcheck --cross-ncs* command showed many errors.

So, I have executed following commands:

samba-tool dbcheck --cross-ncs --fix --yes
samba-tool dbcheck --reindex
samba-tool dbcheck --reset-well-known-acls --fix --yes
samba-tool dbcheck --force-modules
samba-tool ntacl sysvolreset

When I type *samba-tool drs showrepl *command the result is OK.

Now the users authentication is not working proprely, as message below:

root at dc2:~# *wbinfo -a mane*
Enter mane's password:
plaintext password authentication succeeded
Enter mane's password:
challenge/response password authentication failed
wbcAuthenticateUserEx(EMPRESA\mane): error code was
NT_STATUS_WRONG_PASSWORD (0xc000006a)
error message was: Wrong Password
Could not authenticate user mane with challenge/response

I have not yet upgraded my DC primary that is 4.2.1 version.

How can I solve this problem? Is there any bug with Samba 4.5.5 version?

Regards,

Márcio Bacci
