ldap_dn2ufn — Convertit un DN en format UFN (User Friendly Naming)
Convertit le DN dn dans un format plus
lisible humainement, en supprimant les types des noms.
dnLe DN de l'entrée LDAP.
Retourne l'UFN, ou false si une erreur survient.
This function will convert "cn=bryan,ou=users,ou=admin,o=apachetoolbox" to "bryan,users,admin,apachetoolbox".The function of bryan will only work if you start with an Organization and using only an Organizational Unit as a container and the object is an CN.
For example:
$DN = "CN=DNS,CN=Authorized Login Methods,CN=Security";
echo ($DN = ldap_dn2ufn($DN)) . "\n";
echo ($DN = ldap_ufn2dn($DN)) . "\n";
will echo:
DNS,Authorized Login Methods,Security
CN=DNS,OU=Authorized Login Methods,O=Securityfunction ldap_unf2dn($unf,$delimeter=".") {
$seperated = explode($delimeter,$unf); //split the unf up by the given delimeter
$LastKey=count($seperated)-1; //0 is the first key to total-1 would be the last key
foreach($seperated as $key => $value) {
if ($key == 1) { //first variable is the CN
$dn="${dn}cn=$value,";
} elseif ($key == $LastKey) { //last variable, so it's the O
$dn="${dn}o=$value";
} elseif ($value == "") { //value is blank, so continue
continue;
} else { //just a typical OU
$dn="${dn}ou=$value,";
}
};
return $dn;
}
$unf=".bryan.users.admin.apachetoolbox";
$dn=ldap_unf2dn($unf);
print "$dn" // will give me "cn=bryan,ou=users,ou=TS,o=apachetoolbox"Don't know if anyone is interested in this, but this is a modified and more dynamic version of the posting below. Since ldap_dn2ufn takes ',' as delimiter for the UFNs, we'll also use it here. $pHowToBuild specifies, how the DN is going to be build.
Short example:
$myUFN = ldap_dn2ufn("cn=naaina, ou=container1, ou=container2, ou=container3, o=private, c=de");
echo $myUFN . "\n"; // will return "naaina, container1, container2, container3, private, de"
$myDN = $ldapObject->conv_ufn2dn($myUFN);
echo $myDN . "\n"; // will return "cn=naaina,ou=container1,ou=container2,ou=container3,o=private,c=de"
For the object name, $pHowToBuild["object"] is going to be used as prefix - for containers $pHowToBuild["container"] and for the last n elements $pHowToBuild["last"].
