SASL authentication

Hi! I am using OpenLDAP 2.4.26 and trying DIGEST-MD5 authentication using "ldapwhoami". I get the error "SASL(-13): user not found: no secret in database". While specifying the user with -U option, bind DN was showing empty in the server's trace. I have tried specifying complete DN with -D option but the result is the same error.

User were added using sasldblistusers2 command. sasldblistusers shows the users though it has appended the hostname where I issued the add command from.

What am I missing? Can someone point me to working instructions as the documentation for configuring SASL with openLdap seems really sparse?

Thanks
