[2017-08-18T13:23:14.779-05:00 bba76607-42b4-4a15-a3c2-7542f427d12c WARN ] [ActiveDirectoryProvider] There may be a domain join status change since native AD is configured. ActiveDirectoryProvider can function properly only when machine is properly joined

Tried to join domain  but got (Idm client exception: Error trying to join AD, error code [31])

It was because of smb was disabled on PSC (appliances)

run this command

/opt/likewise/bin/lwregshell list_values '[HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\rdr]'

if value is zero of smb  then run this command

1. /opt/likewise/bin/lwregshell set_value '[HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\rdr]' Smb2Enabled 1
2. /opt/likewise/bin/lwsm restart lwio
3. service-controll --stop --all
4. service-control --start -all
5. restart web client on vcenter server
6. then logon psc and try to add PSC in domain
7. If you have secondary PSC , it will take some time for showing domain user.
