I used the "/NOSHELL" value in the passwd file where the shell variable is supposed to be. When I try to "su" or "su -" over to that user and it says, "su: No shell" and will not let me.

So I will state my question again unless I was not clear before. I need to change an existing user lets call him user #1 (who owns a lot of software and scripts I can not break the usability of) from a user you log onto the system as to a user you cannot log on as anymore. I want to be able to log on as a different user (lets say user #2) and then "su" or "su -" over to the user #1 who I can no longer log on as.

Thanks again in advance,
