[Samba] kcc_periodic output

[Elias Pereira]

Hi Douglas, thanks for the answer!!!

samba kcc command = /path/to/samba_kcc --debug


I ran the command and the result is in the pastebin below, if you can take
a look.

But anyway, I don't think this is a samba_kcc specific problem, and

And how can I debug this problem? I've searched everywhere and found
nothing about it.
