Same here.
I follow the intructions for upgrade/migration from centos to rocky.
After pull database from old server , next step is to configure the appliance via web interface.
In this interface no option to join in the domain. Only to type domain name and domain controller ip/host. There's no fields to set username and password credentials for the domain.
This is not serious...
Whatever, after finishing setup and reboot, in the VA screen appears instructions how to finish domain join procedure.
From MORE->Settings->Advanced settings->Active directory.
I follow this instructions and nothing happens too. I do'n know what to do more....
Please, fix this asap!
