rewrite ldaps request

Hello,

I have to rewrite an LDAPs request by an irule. My goal is replace a string by another one. Here is objectClass=person to objectClass=*

I tried differents things but LDAP server doesn't understand what I sent to it.

Here is my code. I put key word "LDAP" in my log to grep it easily

Code
when RULE_INIT {
     translate into hexa
    binary scan "objectClass=person" H* static::class1
    binary scan "objectClass=*" H* static::class2
}

when CLIENTSSL_HANDSHAKE {
SSL::collect
}

when CLIENTSSL_DATA {
     binary scan [SSL::payload] H* temp(hex_ssl_payload)
     if { $temp(hex_ssl_payload) contains $static::class1 } then {
       SSL::payload replace 0 $static::class1 $static::class2
    } else {
            log -noname local0.debug "LDAP request NOK"
}
    SSL::release
}

I don't really know if the tranlation into hexa is the right way.

Regards
