I have a samba server configured that is member of a samba domain called
PRODESAN.COM.BR. After we had to reinstall the domain controller some samba
shares stopped working on the member server. I get this when I try to use
the share:

? check_ntlm_password: ?Authentication for user [USER1] -> [USER1] FAILED
with error NT_STATUS_NO_SUCH_USER
However when I try to use the same user on the domain controller things work
perfectly:

? check_ntlm_password: ?authentication for user [USER1] -> [USER1] ->
[pr907899] succeeded
I can see the domain users using wbinfo -u on the member server and
we have kept the domain SID setting from the original Samba PDC (using net
rpc getsid at the old server) and we still can't authenticate the users.
We have tried to delete the old machine account from our server in order to
try to rejoin it, but now we can't. Here is what happens at the server:
# net join -U root
root's password:

? ads_connect: No results returned

And here are the logs for that machine on the PDC:

There doesn't seem to be any visible errors, so I went to check the LDAP
logs and I only thought this looked a bit strange:

When I check the LDAP I can see that the
entry "uid=servproducao$,ou=computadores,dc=prodesan,dc=com,dc=br" was
created but it doesn't have the sambaSamAccount objectclass attribute, and
therefore no samba attributes set.
Simply importing the old account from the old PDC doesn't seem to work, as I
get some access denied when the server tries to connect to LDAP.
=============================================================
Just adding some more information:
I am currently unable to join any new machines to the domain. Whenever I try
to join the domain I get this message on the clients:
$ sudo net join -U root
Password:
Creation of workstation account failed
Unable to join domain PRODESAN.COM.BR.
On the PDC side I get this:

On my LDAP backend I have this entry:
dn: sambaDomainName=PRODESAN.COM.BR,dc=prodesan,dc=com,dc=br
sambaAlgorithmicRidBase: 1000
sambaNextUserRid: 41000
sambaNextGroupRid: 41001
objectClass: sambaDomain
objectClass: sambaUnixIdPool
sambaSID: S-1-5-21-3756370324-611414431-635963119
sambaDomainName: prodesan.com.br
gidNumber: 1055
uidNumber: 1454
The sambaSID is the same that was before the migration. Do I need to set
this
SID somewhere else?
