Hello!! Hehehe
Then, as already changed the values and problem had my idei and leave 
everything as it was, the two

idmap config *: range = 5000-16777216
idmap config SERVERAD: range = 5000-33554431


It is running more than one year and occurred only problems that I 
changed, I know the right and leave the range as you passed, but I can 
not have the ID change issues again (caused much headache).

So I was in doubt even if the only change
idmap config *: range =
to a lower value as 2000-4500, which impacts can I have?
Since this is not the range of DC User.

Thank you again.
