Some operation can't be reverted with a single reverseLdif element
------------------------------------------------------------------

                 Key: DIRSERVER-1231
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1231
             Project: Directory ApacheDS
          Issue Type: Bug
    Affects Versions: 1.5.3
            Reporter: Emmanuel Lecharny
             Fix For: 1.5.5


There are some operation which can't be reverted if we create a single LdifEntry. For instance,
the following entry :

dn: cn=test,ou=system
objectClass: top
objectClass: person
cn: test
sn: test

on which we apply a modification like a rename where the nex DN will be sn=test+c=us, with
a deletion of the oldRDN, the new entry will be :

dn: sn=test+c=us,ou=system
objectClass: top
objectClass: person
cn: test
c: us

The sn: test value has been removed.

The reverse LDIF will be :

Entry : sn=test+c=us,ou=system
    Change type is MODRDN
    Delete old RDN : true
    New RDN : cn=test

but the sn attribute will be removed, as the c one.

The resultant entry will be :

dn: cn=test,ou=system
objectClass: top
objectClass: person
cn: test

which is different from the original one, because the sn attribute has been removed.

There is no other way than to generate a second modification in order to resuscitate this
removed attribute :

Entry : cn=test,ou=system
    Change type is ADD
        Attributes :
            sn: test

This is mandatory because the 'deleteOldRdn' flag is applied to _all_ the attributes, which
will be all destroyed or kept.

I think that this should be fixed later, as it's a rare condition.
