adamsd, your right, I made a mastake it was NIS not NIM.
We have an HACMP cluster solution where there are 2 physical server's sharing disks. I'm looking for a solution when I change passwords, or create a new user under HACMP, that the passsword gets replicated to the other server. Currently this only happens when I use smit HACMP to create a user, and set their default password. When this happens, the current server that I'm creating the password set's the login so that they have to change it the first time they login. On the other server, if they tried to login with the new password, it doesn't see it. I cannot replicate the passwd file because of how HACMP is configured. (2 servers each one running applications, HACMP kicks in when their is a failure on one, it will change the IP address so the end user won't even know the server failed over. When this happens, its going to try and read the local passwd file on the other server, and this is where the problem lies).
I know this sounds complicated, but you'd have to understand how our HACMP configuration works.
