  1. Hi raja. We have a solaris 10 server and I have one issue which I unable to solve. I hope you could help me with it. I was trying to install one application and I needed to change the owner and group users for certain files. By, mistake I guess the system files ownership to changed. I have root access and when I access my SUN OS using putty terminal. I had to restart my server since it wouldn't login to the server. While restarting my server I get an error "Error opening PAM libraries contact system administrator". I googled and noticed that you need the Solaris boot cd to revert the pam.config file. But, I do not have my Solaris CD anymore. How else can I revert this file? Please do let me know your expert advice. Thanks in advance.
