[Samba] Problems joining station in domain

[Marcio Demetrio Bacci]

Hi,

I'm having trouble entering stations in the domain, as message below:

"

*error while attempting to join domain "EMPRESA"security id structure is
invalid*"

In the log I see the following message:

tail -f /var/log/samba/log.samba
[2019/08/26 15:17:12.206883,  0]
../source4/dsdb/common/util_samr.c:192(dsdb_add_user)
  Failed to create user record
CN=COMP0084,CN=Computers,DC=empresa,DC=com,DC=br: acl: unable to get access
to CN=COMP0084,CN=Computers,DC=empresa,DC=com,DC=br

My user is Administrator and before was working.

The station is Windows 7 Professional and my DCs are Samba 4.

How could you solve this problem?

Regards,

Márcio Bacci
