Correct.  You can set up chain on update to have "global" lockout - see

Yes.  Those attributes are operational attributes - you have to ask for 
them explicitly in the ldapsearch request.  You should be able to set 
them manually as directory manager.  But for now, the problem is that 
the changes are in the changelog and the server is attempting to 
replicate them.  I suggest setting the isglobal attribute in the 
replica, allowing the change, then disabling the replication of those 
attributes and disabling global policy.
