Authentication - domain server connection fails
We have several customers with Firebox devices (T15, T30, M270)
Our standard setup includes adding domain authentication.
Via the GUI we do the following
and add the active directory domain name, Enable secure SSL connections to your Active Directory server (LDAPS) is left unticked.
Normally after adding the active directory as an authentication server we run the "Test connection for LDAP and active directory" using an admin account.
This is a very simple configuration and test but on one customer (the Firebox M270) the test connection fails.
Connect to server: Failed (can't connect to aohl.co.uk[server is down or unreachable])
Log in (bind): Failed (unknown)

Any thoughts on how to troubleshoot / resolve this issue.
Thanks in advance
