Second level authentication.

Hi Stefan, I read the document and thanks for giving the link, that was helpful. Well I think i put my question in a wrong way. Let me put it in a different way. I dont want the user to go directly in priv mode. through priv level = 15 we direclty get into priv level right. what i am looking for is first the user get into user level and then with another password in level 2. (not with enable password)..it should be through RADIUS server. Ashish
