Hi list!
We have two Server with Debian 11 and Samba 4.13.5 (from Debian repositories) that have to connect as member to our AD.
Our goal is, that our users can use the shares on the Servers using their AD credentials.
So I configured Samba and joined the domain. No problems and all worked some weeks.
Suddenly, without any changes in the configuration or other action on the Server, they can't speak with the AD anymore.
We already had the problem and a rejoin has solved the problem, but now we have the problem again, so I'm searching a better solution.
I see, if I try to ping the DC:
root at nasmedia02:/etc/samba# wbinfo --ping-dc
checking the NETLOGON for domain[AD-QUEO-ORG] dc connection to "" failed
failed to call wbcPingDc: WBC_ERR_DOMAIN_NOT_FOUND
and
root at nasmedia02:/etc/samba# wbinfo --check-secret
checking the trust secret for domain AD-QUEO-ORG via RPC calls failed
wbcCheckTrustCredentials(AD-QUEO-ORG): error code was NT_STATUS_DOMAIN_CONTROLLER_NOT_FOUND (0xc0000233)
failed to call wbcCheckTrustCredentials: WBC_ERR_AUTH_ERROR
Could not check secret
Can someone help me?
Other Server, with Debian 10 don't have the problem with the same configuration and Samba 4.9.5.
Thanks a lot
