Hi! I have appended to /etc/security/access.conf: -:nice:ALL And this to /etc/pam.d/login: account required pam_access.so And the I try to login as "nice" to the machine, and it works! I thougt that that line would make me not able to login. Do I have to restart something? What is the problem? Im running NIS, could that be whats causing trouble? I dont know whats the problem. Im not sure that login is the right file. What am I missing? Thanks!! /nisse
