We have been testing the NW 6.5 SP6 software in our test lab and so far
on 4 different servers we are continually prompted to extend the schema.

It will not continue if you do not enter an account that has rights to
extend the schema.

We had installed SP6 on our Root Master server and waited until the
schema syncd to all servers. Why is is prompting us each time to extend
the schema?

We have a distributed environment where junior level admins do not have
rights that far up the tree to do the schema extension.
