a broken implementation of the funcion from_match on pam_access can make tests on ip address to fail. if using (on /etc/security/access.conf) something like : *:user:200.48.36.195. *:user:200.48.115.55. -:user:ALL the test for a connection from ip address 20.48.36.195 doesn't result on a connect. attached patch that helps the problem
Created attachment 16505 [details] fixes buffer size, adds trailing dot to the test
This should be fixed in pam-0.75-2 and later. Thanks!
