[Samba] Warning messages when provisioning an ADDC

[Thomas Geppert]

I've installed and provisioned a Samba ADDC in an unprivileged Linux
container. The details can be found in my post "Samba AD DC in an
unprivileged lxc revisited".
The ADDC seems to work properly but there is one detail that still bothers
me. In the output of samba-tool were the following warnings:
INFO 2021-02-02 19:51:42,853 pid:942

Can someone shed a light on what's causing these "Unknown gid" messages and
what it could mean for the operation of the ADDC ?

Thanks !
