Error: MDM failed command. Status: Commands sent on an unsecure connection are not allowed.

Hello,

I've just upgraded my ScaleIO POC from 1.32-3 to version 2.0

My config is :

10.0.5.110 Primary MDM

10.0.5.111 Secondary MDM

10.0.5.112 Tie Breaker

After upgrade I've tried to secure connections with the following instruction on the secondary  mdm (10.0.5.111) who was active:

# scli --login --username=admin --password=xxxxxxxx --use_nonsecure_communication

# scli --set_component_authentication_properties --use_authentication --use_nonsecure_communication

# scli --set_management_client_communication --enable_client_secure_communication --use_nonsecure_communication

# scli --switch_mdm_ownership --new_master_mdm_ip 10.0.5.110

# reboot

Now, when I try to login on the other mdm (10.0.5.110), I get the error message :

[root@labdat1 ~]# scli --login --username=admin --password=xxxxxxx

Error: MDM failed command.  Status: Commands sent on an unsecure connection are not allowed.

How can I "securely" connect to the mdm 10.0.5.110 ?

The connection on the mdm 10.0.5.11 (where i launch the previous commands) works fine

Thanks in advance for help

Daniel
