I know it's possible in R6, but we have a R5, so I'm not sure if I can do it.
As far as I am aware, the routine was completely modified in ND6 to have name changes, certificate expirations and so on automatically processed by the client during the authentication process. In R5, this is performed ONLY via user interaction (i..e, the "Accept name change" dialog you refer to).
I am not aware of any process to automate this in R5 (including APIs).
