(Optional) Click Start Test. This will test the settings you have entered, ensuring they are correct before 
real users use them to authenticate. For details on the testing performed, see

Once you submit and commit your changes, you cannot later change a realm’s authentication protocol.

Create an Identification Profile that uses the Kerberos authentication scheme. 

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.

Deleting an authentication realm disables associated identities, which in turn removes those identities 
from associated policies.

Deleting an authentication realm removes it from sequences.

Configure Global Authentication Settings to apply settings to all authentication realms, independent of 
their authentication protocols.

The Web Proxy deployment mode affects which global authentication settings you can configure. More 
settings are available when it is deployed in transparent mode than in explicit forward mode.

Be familiar with the following concepts:
