[horde] hook to select default identity

[LALOT Dominique]

Hello,

I would like to push tow identities for a user thanks to a hook. The user
then would be able to select one of the identities.
How can I dot that?
I'm already using the hook from_addr

The initial purpose is to switch from a domain to another one and let the
user choose what identity to use.
I played with identities and hook. I was able to add identities, but then
the user is able to change the values and delete the identities. How can I
protect? I put these values in prefs.local.php

$_prefs['default_identity']['locked']=false;
$_prefs['default_identity']['value']=0;
$_prefs['identities']['locked']=true;
$_prefs['identities']['hook']=true;
$_prefs['from_addr']['locked']=false;
$_prefs['from_addr']['hook']=false;

and in the hook (sorry, I'm rather a PERL programmer)

        case 'identities':
                 $ds = $this->_ldap_connect();

 $justecela=array('displayname','mail','amumail','maillocaladdress');
                 $searchResult = @ldap_read($ds,
'uid='.$username.','.$searchBase,'uid=*',$justecela);
                 $information = @ldap_get_entries($ds, $searchResult);
                 $user = $information[0]['displayname'][0];
                 $amumail = $information[0]['amumail'][0];
                 $mail = $information[0]['mail'][0];
                 ldap_close($ds);
                $default=array('from_addr'=>$amumail,'fullname'=>$user,'id'
=>'univ-amu');
                $old=array('from_addr'=>$mail,'fullname'=>$user,'id'
=>'univmed');
                $Talias=array();
                foreach ($information[0]['maillocaladdress'] as  $alias){
                   if ($alias==$mail or $alias==$amumail) continue;

 $Talias=array_merge($Talias,array('from_addr'=>$alias,'fullname'=>$user,'id'
=>$alias));
                }
                $ident=array($default,$old,$Talias);
                return(serialize($ident));








Thanks in advance
