/**
* Updates or deletes a value from a specified attribute for a specified dn.
*
* Variables that come in via common.php
* - server_id
* Variables that come in on the query string:
* - dn (rawurlencoded)
* - update_array (an array in the form expected by PHP's ldap_modify, except for deletions)
* (will never be empty: update_confirm.php ensures that)
*
* Attribute deletions:
* To specify that an attribute is to be deleted (whether multi- or single-valued),
* enter that attribute in the update array like this: attr => ''. For example, to
* delete the 'sn' attribute from an entry, the update array would look like this:
* Array (
* sn => ''
* )
*
* On success, redirect to template_engine.php. On failure, echo an error.
*
* @package phpLDAPadmin
