- Verify Active Directory is installed and you have access to at least one Windows computer acting as a domain controller for the Active Directory forest to which you want to add UNIX computers.
- Check the configuration of DNS and whether you are using a Windows computer as the primary DNS server.
- Verify the DNS server allows secure dynamic updates and your domain controllers are configured to publish updated service locator (SRV) records.
- Verify DNS resolution and network communication between the UNIX computers and the Active Directory domain controller. You can use the ping command to test communication between the domain controller and the UNIX computer.
