ldap_dn2ufn — Convertir un DN a un formato de nombramiento amigable al usuario
Convierte un dn específico, a un formato más amigable al usuario,
mostrando los tipos de nombre.
dnEl nombre distinguido de una entidad de LDAP.
Devuelve el nombre amigable al usuario.
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"].
