Verifying the DNS configuration on Linux

Centrify Authentication Service uses DNS to locate domain controllers for the Active Directory forest. To verify the Active Directory domain controller can be located through DNS, try sending a ping request to the computer.

You can also run the adinfo --diag command to attempt to read the DNS records for the domain you want to join. For example:

adinfo --diag domain_name 

If DNS is properly configured, the command should display the LDAP URLs for the domain controllers in the domain you want to join.

For more detailed information about configuring DNS or troubleshooting your DNS configuration, see the Administrator’s Guide for Linux and UNIX.
