Hi; I have been reading about the PAM module. I have downloaded Authen-PAM-0.11 so I can access the PAM module using Perl. What I want to do is. Limit my users so they can not have two logins at once. I also would like to use this module to track my 30 and 90 hour a month accounts, so we can track over usage. I would like to also set up our users with a SSL ability, so our customers can use outlook express. I just wanted to know if there were any modules out there which I can use to do these tasks before I look into programming my own modules to handle these issues Any and all help will be appreciated; Ken Rhodes Webmaster Webside Communications Ltd. http://www.webside.ca
