Custom domains

If the environment is configured with a custom domain, only one SPN is required. The address varies depending on the DNS result. See the examples below for more information.

Example 1: DNS result from nslookup
c:\>nslookup -type=A sso.example.com
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa
        primary name server = 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa
        responsible mail addr = (root)
        serial  = 0
        refresh = 28800 (8 hours)
        retry   = 7200 (2 hours)
        expire  = 604800 (7 days)
        default TTL = 86400 (1 day)
