Well I think there are three basic ways to change the way you handle authentication. One system is pam where the application that needs authentication uses the pam library. In that case each application has a file where you can specify which pam module it should use for authentication, changing passwords, and so on. There are modules for passwd file, NIS, ldap, windows authentication, etc. Another system is to recompile each appplication to use the authentication you want. This is pretty ugly. I think another possible way would be through the C library. I believe that the C library has certain authentication functions (I think for passwd file and NIS). I think that you could modify these functions to provide whichever method you want. > For instance, if i would now like to change the way users are > authenticated, how would i do that. > Any info on this? As I have said, passwd file authentication and NIS are probably built into the C library so those should be OK to set up. To use anything more complicated might require messing with the C library or recompiling programs. Hope that helps, Bijan -- Bijan Soleymani <[EMAIL PROTECTED]> http://www.crasseux.com
