Couldn't create computer account: CN=F3BLK21, CN=Computers, DC=Domain, DC=com
problem 1006 (ATT_OR_VALUE_EXISTS), ATT 90303 (servicePrincipalName)
The machine hasn’t been added previously to the domain (Checking AD I can confirm there’s no computer object there for that machine).
Also this works fine on Centos 7 and Red Hat. All the same packages for Centos 7 and Red Hat 7 for this purpose is also installed on Fedora.
