Hello Quanah, Thank you for your answer (and sorry for double-reply, I forgot to answer to all at first time).

Actually, I did not set a real password, only, as I saw in examples : userPassword: {SASL}user@realm (you don’t directly see it in the extracts I provided because the password there is base64 encoded). I tried setting only, as you suggested : userPassword: {SASL} but I don’t have any better result. Regards, Stéphane
