[Samba] Primary group is 0 and contains 0 supplementary groups

[Elias Pereira]

Hello,

We have a rfs6000 wifi model controller from Extreme Network that has the
ability to become a member of the AD. When we configure it according to
Extreme support, the error "NT_STATUS_LOGIN_FAILURE" on the controller and
in the samba logs shows the following errors.

We have already tried to use the "administrator" and also a common user
with "unix attribute" to put the controller in the domain, but without
success.

Every help is welcome.
