  Authentication Realms
Security appliance is managed by a Security Management appliance, be prepared to ensure that 
same-named authentication realms on different Web Security appliances have identical properties 
defined on each appliance. Be aware that once you commit the new realm, you cannot change a 
realm’s authentication protocol.
For NTLMSSP, single sign on (SSO) can be configured on client browsers. See 
.
Using Multiple NTLM Realms and Domains
The following rules apply in regard to using multiple NTLM realms and domains:
You can create up to 10 NTLM authentication realms.
The client IP addresses in one NTLM realm must not overlap with the client IP addresses in another 
NTLM realm. 
Each NTLM realm can join one Active Directory domain only but can authenticate users from any 
domains trusted by that domain. This trust applies to other domains in the same forest by default and 
to domains outside the forest to which at least a one way trust exists.
Create additional NTLM realms to authenticate users in domains that are not trusted by existing 
NTLM realms.
Step 1
Choose Network > Authentication.
Step 2
Click Add Realm
Step 3
Assign a unique name to the authentication realm using only alphanumeric and space characters.
Step 4
Select Active Directory in the Authentication Protocol and Scheme(s) field.
Step 5
Enter up to three fully-qualified domain names or IP addresses for the Active Directory server(s).
Example: 
active.example.com
An IP address is required only if the DNS servers configured on the appliance cannot resolve the Active 
Directory server hostname.
When multiple authentication servers are configured in the realm, the appliance attempts to authorize 
with up to three authentication servers before failing to authorize the transaction within this realm.
Step 6
Join the appliance to the domain:
a.
Configure the Active Directory Account:
b.
Click Join Domain.
Setting
Description
Active Directory Domain
The Active Directory server domain name. 
Also known as a DNS Domain or realm. 
NetBIOS domain name
If the network uses NetBIOS, provide the domain name. 
Computer Account
Specify a location within the Active Directory domain where AsyncOS 
will create an Active Directory computer account, also known as a 
“machine trust account”, to uniquely identify the computer on the domain. 
If the Active Directory environment automatically deletes computer 
objects at particular intervals, specify a location for the computer account 
that is in a container, protected from automatic deletion.
