How to enter in AD FreeNAS?

Question

FreeBSD

Previously, according to some instructions, I introduced freeNAS into the domain, but then it didn’t work, due to a lack of RAM to work with ZFS, the server was unstable and it didn’t work, now I decided to make storage for backups on UFS, on the same machine, but The past flash drive has already gone and I'm setting it up again.
Found a seemingly great how-to with pictures for people like me
forums.freenas.org/index.php?threads/how-to-proper...
but as a result of fiasco:
# wbinfo -t
checking the trust secret for domain STP via RPC calls failed
error code was NT_STATUS_NO_SUCH_DOMAIN (0xc00000df)
failed to call wbcCheckTrustCredentials: WBC_ERR_AUTH_ERROR
Could not check secret
# net rpc info
Enter root's password:
Could not connect to server SRV-SHR
The username or password was not correct.
Connection failed: NT_STATUS_LOGON_FAILURE
deleted from AD, DNS, DHCP a record about the past server, changed IP, name, users, nothing helps.
swears at the user-password, but I tried both the account I created for freeNAS and the account with domain administrator rights, nothing changes.

Answer 1

for some time everything turned out, somewhere it’s obvious, I didn’t do something carefully

Answer 2

Is the server available? Is the ping coming? Did you connect by the full name of the controller?

Answer 3

Are you allowed to connect to the domain without encryption?
