Hello,

I need to reply an deniedServices ldap variable in Class attribute for a
controller. I added it
"replyItem    Class   deniedServices +=" at ldap.attrmap file.
and sites-available/default file includes it. But it override the Class
value to empty.
                update reply {
                                Class += "%{Reply-Message}"
                }


Where it is wrong?
