Installation error saying Each SPN must be unique across the forest

Hi,

Trying to install Centrify 5.2.3-429 on Solaris 10, I'm getting the following error toward the end of the installation and the server cannot join the domain.

With an older version of Centrify, I had no problem on the same server to join the domain, etc.

Accounts that contain same SPNs is:
CN=dc4orapc5n4,CN=Computers,DC=mycompany,DC=priv

Each SPN must be unique across the forest. Please make sure the SPNs listed above are unique across the forest before joining.

Join to domain 'phx.mycompany.priv', zone 'Auto Zone' failed.
join failed


Error detected. More information may be found in the logfile
(location is /var/log/centrifydc-install.log).
Exiting ...

Any advice on what to do to fix the issue?

Thank you in advance!
