!!! Overview[1]
[{$pagename}] is a [LDAP ModifyRequest Operations] within an [Modify Request]

If the [Modify Request] is a [{$pagename}] and there is an attribute description without any values, then all values for the specified attribute will be removed from the entry. 

Under normal circumstances, a [Modify Request] that is a [{$pagename}] __cannot__ be used with the [{$pagename}] to remove an attribute that does not already exist. 
\\__NOTE:__ the [Replace Modification-type] can be used to accomplish this.

If the [Modify Request] is a [{$pagename}] and there is an [Attribute Type Description] with one or more values, then only the specified values will be removed from the entry. 

!! [LDIF Example]
The [{$pagename}] [ChangeType] is used to __delete__ values from a [LDAP] [TargetDN] and is used the same as the [Modify Request]. 

A [{$pagename}] change record requires two items: 
* the [TargetDN] of the entry to delete
* the modify [changeType] with the [{$pagename}] directive

The following [example] __deletes__ the jdoe@novell.com value from the mail attribute. If the attribute does not contain the specified value, the operation fails. 

However, if the purpose was to ensure that the specified value did not exist in the attribute, the operation succeeds in achieving the desired result.
{{{
version: 1
dn: cn=johndoe, ou=provo, ou=users, o=novell
changetype: modify
delete: mail
mail: jdoe@novell.com
}}}

The following [example] __deletes all values__ of the mail attribute. If the attribute does not exist, the operation fails. 

However, if the purpose was to ensure that the attribute has no values, the operation succeeds in achieving this result.
{{{
version: 1

dn: cn=johndoe, ou=provo, ou=users, o=novell
changetype: modify
delete: mail
}}}
