RE: Modify only one attribute that has multiple values of the same name

[Brian Gaber]

Francis,

I have read it on CPAN.  I guess I missed that part.

Thanks.

Brian,

What you really want is:

$del_msg = $ldap->modify( $dn,
        changes => [
                # delete old value
                delete => [ SFTrule => [ "$old_value" ] ],
                # add new value
                add => [ SFTrule => [ "$new_value" ] ]
        ]
);

Why do both the add and delete in a single modify?  So that it is treated as an 
atom and if EITHER fails, NEITHER happens (which is the creed -- "at the very 
least, do no harm")

This is straight out of the perl-ldap documentation, have you read it?

- Frank
