Hello,
I'm running Samba 3.2.5 on Debian, with tdbsam backend.
For the past few days, I've had trouble with starting Samba (which I
do routinely once a day) but with users unable to login on Windows
workstations.
When this happens, the current smbd.log shows no activity (not even
the "starting samba" event) and the previous day's smbd.log shows
entries like these:
[2009/10/24 19:41:38, 2] auth/auth.c:check_ntlm_password(308)
check_ntlm_password: authentication for user [user1] -> [user1] ->
[user1] succeeded
[2009/10/24 19:41:38, 1] smbd/service.c:make_connection_snum(1198)
pc03 (::ffff:10.0.4.98) connect to service user1 initially as user
user1 (uid=1047, gid=100) (pid 7744)
