They are out of scope of the winsync agreement.

Let's say you have in AD
cn=Users,dc=example,dc=com
cn=Adminusers,dc=example,dc=com

and in IPA
cn=users,cn=accounts,dc=example,dc=com

and you set up your winsync agreement as

nsds7WindowsReplicaSubtree: cn=Users,dc=example,dc=com
nsds7DirectoryReplicaSubtree: cn=users,cn=accounts,dc=example,dc=com

That is, you want users in cn=Users,dc=example,dc=com to be in sync with 
cn=users,cn=accounts,dc=example,dc=com

IPA uses a flat dit - users are grouped not by hierarchy but by 
attributes, as opposed to AD which uses hierarchies for grouping.  So 
IPA "flattens" hierarchies when it syncs users from AD to DS.

Let's say you have
cn=jsmith,cn=Adminusers,dc=example,dc=com with samaccountname: jsmith
and
uid=jsmith,cn=Users,dc=example,dc=com

because of the way that winsync works, it will think because the AD 
entry and the IPA have the same userid, they should be in sync - but 
because cn=jsmith,cn=Adminusers,dc=example,dc=com is outside the scope 
of cn=Users,dc=example,dc=com winsync will think that the user has moved 
outside the scope of the agreement, and will delete the user.  Obviously 
it should not do that by default, hence 
https://fedorahosted.org/389/ticket/355

But why do you have users with the same userid in AD out of the scope of 
the sync agreement with the same userid as an IPA user?
