Hi, After some months with SELinux in Permesive mode ... Some avc: denied messages were recorded ... I thought it was time for SELinux Enforcing mode in a CentOS-5.2 server with mail(postfix+cyrus+sasl), web, snmp with mrtg, squid ... it also has a local TLS configured for webmail access ... I took a look to the RedHat Deployment Guide about how to do it ... and tried to build modules with audit2allow from the /var/log/message to allow some denied messages so the applications could work on a SELinux Enforcing mode (is that ok ?). The created modules seem to work fine, because old avc denied messages desappeard ... but some messages like the following appear at /var/log/messages when I do use a semodule -i modulename.pp or semodule -r modulename : Oct 5 20:16:11 orion kernel: : exe="?" (sauid=81, hostname=?, addr=?, terminal=?)'

Also, in the /var/log/httpd/ssl_error_log the following messages begin to appear : [Sun Oct 05 19:58:19 2008] [warn] RSA server certificate is a CA certificate (BasicConstraints: CA == TRUE !?) [Sun Oct 05 19:58:19 2008] [warn] RSA server certificate CommonName (CN) `example.com' does NOT match server name!? Really rare because that name `example.com' is the actual server hostname. When try to connect to the webmail through https:// can't connect to it, the browser reports connection failed after a waiting of a few seconds. http:// works as expected.
