What happens when you extend the Active Directory schema during ldap setup?

[Ryan Gro]

I'd like to know exactly what happens when I extend the schema of the Active Directory server during the ldap configuration setup.

I know it adds a new "classSchema" called "DUAConfigProfile" which defines the type and attributes of the ldap-ux configuration file that you download to the server.
But does it add or remove attributes anywhere else?

Thank you again,
Ryan
