Hi Michael,
Thanks for the response. I think I found the reason for the error. It seems
to be necessary to append ";binary" to the attribute name while
adding/modifying binary attributes. So for instance if I am
adding/modifying userCertificate, I will have to use the attribute name
"userCertificate;binary". Else you are likely to get an undefined attribute
/ binary transfer failed error.
