How to move an eDirectory entry via php?


I have this ldap entry:

cn=blah,ou=apples,ou=people,dc=yay,dc=edu

I need to move that entry to:

cn=blah,ou=oranges,ou=people,dc=yay,dc=edu

My scripts are all PHP so I've been trying to use php.net/ldap_rename

ldap_rename($connection, "cn=blah,ou=apples,ou=people,dc=yay,dc=edu", "cn=blah", "ou=oranges,ou=people,dc=yay,dc=edu", true);

Does not work. It returns false.

This https://www.php.net/manual/en/function.ldap-rename.php#82393 comment mentions that eDirectory wants to leave the parent as NULL. Like:

ldap_rename($connection, "cn=blah,ou=apples,ou=people,dc=yay,dc=edu", "cn=blah", NULL, true);

That returns TRUE but does not actually move the entry. Not surprising since it's not changing the parent... I'm sure it could change the cn=blah to something else...

I have thought of deleting the entry and recreating it. But that's a painful way to go about it. Writing out and running a LDIF file would also be painful.

So, how do I move an entry from one OU to another, in php, without the pain of my other two options?

What I'm running:

Edit

So, I found this:

The modrdn change type cannot move an entry to a completely different subtree. To move an entry to a completely different branch, you must create a new entry in the alternative subtree using the old entry's attributes, and then delete the old entry.

From http://www.centos.org/docs/5/html/CDS/ag/8.0/Creating_Directory_Entries-LDIF_Update_Statements.html

I found a couple other pages with similar statements.

So it sounds like I have to make a new entry, copying the attributes, the delete the old one. Like the second painful option I mentioned above.


Solution

  • Well, I ended up using the "create new entry, delete old one" method. I still think I had another way working a while back, but I can't remember what. So here's a basic move function.

    function move($connection, $ldapEntryReference, $new_dn){        
        //First, get the values of the current attributes.
        $attributes = array(); //start attributes array
        $firstattr = ldap_first_attribute($connection, $ldapEntryReference);
        $value = ldap_get_values($connection, $ldapEntryReference, $firstattr);
        $attributes[$firstattr] = $value;
        while($attr = ldap_next_attribute($connection, $ldapEntryReference)) {
            if (strcasecmp($attr, 'ACL') !== 0) { //We don't want ACL attributes since 
                                                  //eDir/ldap should deal with them for us.
                if (strcasecmp($attr, 'jpegPhoto') === 0) {
                    //binary values need to use the ldap_get_values_len function.
                    $value = ldap_get_values_len($this->connection, $ldapEntryReference, $attr);
                } else {
                    $value = ldap_get_values($this->connection, $ldapEntryReference, $attr);
                }
                $attributes[$attr] = $value;
            }
        }
        //Create a new entry array with the values.
        $entry = array(); //start entry array.
        foreach($attributes as $key => $value) {
            foreach($value as $key2 => $value2) {
                if (strcasecmp($key2, 'count') !== 0) {//get rid of 'count' indexes
                                                       //ldap_add chokes on them.
                    $entry[$key][$key2] = $value2;
                }
            }
        }
        //Add the new entry.
        if (ldap_add($connection, $new_dn, $entry)) {
            //Delete the old entry.
            if (ldap_delete($connection, ldap_get_dn($connection, $ldapEntryReference)) {
                return true;
            } else {
                return false;
            }
        } else {
            return false; 
        }
    }
    

    Hopefully this helps someone, sometime.
