I tried the tombstoneLifetime attribute modification on an test setup in 
my office which has two ad DC's both running on an debian wheezy vm's, 
one runs sernet 4.1.3 the other one an backported debian samba package 
version 4.0.10. The server i modified the attribute on was the one with 
sernet 4.1.3 and this one also has alle the fsmo roles. Here it did not 
take long till the deleted objects started decreasing after i restarted 
that server. Just checked both servers and they habe no replication 
errors and both show the same number of ~390 deleted records. Before one 
of my windows 7 clients alone had around 800 deleted records.
Are you shure you changed tombstoneLifetime to an small enoght value to 
cache some of your deleted records? I'd also verify that the 
tomstoneLiftime attribute replicated successfull to all your dc's.

This means that schema updates are not allowed on that server. It's 
unrelated to Configuration changes or DNS updates.
