I can bind as a user by configure in virtual server

authorize {
update {

control:Auth-Type := ldap
}
}

It works well and can authenticate a user with LDAP .

The "radiusd -X" output like

(2) ldap : Performing search in 'ou=a,dc=b,dc=domain' with filter '(sAMAccountName=abc)'

(2) ldap : Waiting for search result...
(2) ldap : User object found at DN "CN=s,OU=s,OU=s,OU=a,DC=b,DC=domain"
(2) ldap : Waiting for bind result...

(2) ldap : Bind successful
(2) ldap : Bind as user "CN=a,OU=ab,OU=a,OU=qiyi,DC=b,DC=domain" was successful

What I want to do is update reply:Reply-Message with the user information, such as

reply:Reply-Message := "CN=a,OU=ab,OU=a,OU=qiyi,DC=b,DC=domain"

I've tried to update reply in "mods-available/ldap", but it not work.

Is it possible? Any suggestions will be appreciated.
