Hello,
Just yesterday, we installed the new samba version - 4.18.1 - and
configured AD domain controllers. Samba service started without any
issues. But with in 10 minutes of starting the service entered failed
state. Restarting the service is also resulting in the same issue.
Service enters failed state with in 15-20 minutes
I have deployed samba on RHEL 8.
When the service enters the failed state, we logs shows as follows. How
do we fix it?
