That's correct - it is an error to delete an attribute that doesn't exist.
When you get the error back the server ignores the entire modify operation
you sent it, so you need to make sure the error doesn't happen.

Another approach, if you are using LDAPv3 (note Net::LDAP does not use
LDAPv3 by default) is to use a 'replace' with your attribute name and no
values. In LDAPv3, this is defined to always work even if that attribute
doesn't exist in the entry.

ie:

my $mesg = $ldap->modify( $entry, replace => { %qv_del_arry } );

But make sure you are using LDAPv3, because that is defined to *not* work
in LDAPv2. (A nice incompatibility between LDAPv2 and LDAPv3.)
