Failover DC did not work when Main DC failed
Unless it's _not_ a global catalog. Check your SRV records again, there
should be corresponding "_gc" records (similar to "_ldap") for each DC.
So, based upon the link/graphic I posted earlier:
* either your 2nd DC isn't being returned as a part of DNS lookups
* or that 2nd DC isn't responding to queries for authentication
* or the client isn't

Ah, OK... so we don't need to worry about that then?

Failover DC did not work when Main DC failed
What do you see/get when you run:
dig NS $(hostname -d)
With 2 dc's you should see 2 records.
In the past this was a bug at samba joins so only 1 NS record existed.
Worth to have a look at.
And adding this to /etc/resolv.conf:
options timeout:2
options attempts:3
options rotate
Also might help.

Moving DC1 to a Virtual Machine
just a suggestion..
get www.xenserver.org install a xen server.
get xen convertion tools. http://www.citrix.nl/downloads/xenserver/tools/conversion.html
and migrate the linux on hardware box to Xen server.
from here you can also export to OVF/OVA package or XVA file.
the OVF can be inported in virtual box..
but i do everything with xen server.

GPO, multiple DCs, sites and sysvol
This is all about DC location
My workstations are correctly assigned to sites and correctly use their
site DC to authenticate
But this does not apply to Sysvol connection establishement (I saw a
workstation on site A, authenticated on DC of site A (alive), fetching
GPO from site B, no matter the configuration). To me it seems to be
related to the lack of DFS handling

Windows 2008R2 DC Problems
Hi Guys,
I was thrown off by the subject and would love to know if you could ever
resolve this problem.
I'm facing the same issues.
For various $reasons I need an additional Windows DC in my domain and as
Moe described everything looks fine until you try DNS stuff.
My environment:
DC-01 (Ubuntu 12.04 LTS)
DC-02 (Ubuntu 12.04 LTS)
Samba: Version 4.1.17 (build from sources)

Can only enable Sieve scripts not edit them (Roundcube)
Hello,
(my first post so be gentle)
I will be posting this to the Roundcube mailing list too, but thought it worth asking here as well.
I have a Roundcube installation running Apache with Dovecot and Sieve.
When logged in to Roundcube, a user can see the Sieve scripts and enable or disable them but NOT edit them or create new scripts.
In other words, Dovecot will happily EDIT the script to

Samba4 Secondary DC Replication Concerns
Hi Folks
If I have 2 x Samba4 AD DCs, a primary and secondary, am I correct in assuming that if I add a Windows Client to the DOMAIN it should eventually replicate to the secondary DC?
