I'm testing a samba4 server join AD (had 1 win2003 dc) as dc. Version:
Samba4 DC: samba 4.1.1 with ubuntu (172.16.3.8)
Win2003 DC: Win2003 SP2 (172.16.3.3)
AD domain name: dotest.com
The samba server had joined to AD as DC. When win2003 dc online, it seems
works fine.
When I test win2003 dc online, simulate the win2003 DC was failue, found
the samba4 DC can't work fine along. The AD client logon has been very
slow. And there are error log in the samba4 dc log file
/usr/local/samba/var/log.samba:

winbind, ntp_signd, kcc, dnsupdate

[netlogon]
path = /usr/local/samba/var/locks/sysvol/dotest.com/scripts
