Altavault not joining Active Directory

[dannchen]

I'm trying to joing an Altavault virtual appliance to and active directory.

I've entered the FQDN, user and password.

The following message appears:

Joining domain <FQDN of my active directory> failed. Please see the system log for details.

This are the logs outputs

I've tried searching the error, but all I find are not related to altavault nor similar.

Hi Dan, 

Is the altavault and Domain servers in different time zones ? Did you check if there is any time lag more than 5Mins ?

Thanks,

Nayab

NERR_DCNotFound suggests the AltaVault was unable to use DNS to locate an AD server within that domain.  

Test DNS resolution manually with a windows client

 C:\> nslookup -q=srv _ldap._tcp.dc._msdcs.<domain name> <dns server IP>

Test DNS resolution manually with a *nix or Mac client

# dig @<dns server IP> -t SRV _ldap._tcp.dc._msdcs.<domain name>

I had the same issue, upgrading from v4.1.1 to v4.2.  Due to our AD structure the AVA didn't handle the FQDN and NetBios name correctly.  Had to downgrade (reinstall basically).  There is now a v4.2P1 available that made the difference for me.

In addtion under v4.2.1 it helps to add host entries to the AVA for your Domain Controllers (Configure - Host Settings - Hosts).
