[ome-devel] Failed root logins at midnight

[Rainer Poehlmann]

Hi Ola,

nope, I already checked this.
 From by naive thinking this must be somehow "internally" triggered.

If I scan the Blitz-0 log file I can see about 8000-10000 "AUTH" events per day originating from "user=0" (out of 
80000-90000 in total for _all_ users).
But why is root always failing ad midnight?!?

Puzzled ....

Thanks & regards,
-Rainer
