Hi Todd,
Thank you for your answer.
The log Failed to connect to SMD server - user: null shows that the user is null... However, the secstore.properties file (in SMDAgent/configuration) is the following :
$internal/version=Ni4zMC4wMDAuMDAx
smd/agent/Password=amF2YS5sYW5nLlN0cmluZ3wxMnxTTURVc3JTdXAxMjckJCQkJCQkJA\=\=
smd/agent/User=amF2YS5sYW5nLlN0cmluZ3w5fFNNRF9BRE1JTiQkJCQkJCQkJCQk
$internal/mode=Not encrypted

sld/usr=amF2YS5sYW5nLlN0cmluZ3w5fFNMRERTX1M5MCQkJCQkJCQkJCQk
And, I already checked the roles of SMD_ADMIN user.
Best regards, Nicolas
