Hi, I posted this question in selinux group a few days ago, but so far no response. So, I post it here and hope can get some help. My system: os: RedHat FC3 linux, kernel-2.6.10-1.760_FC3, selinux enforced, iptables enabled selinux: selinux-policy-targeted-1.17.30-2.75 iptables: iptables-1.2.11-3.1.FC3 web sever: httpd-2.0.52-3.1 sendmail: sendmail-8.13.1-2 squirrelmail: squirrelmail-1.4.3a-6.FC3 SELINUXTYPE=targeted The problem is that the SquirrelCheck in squirrelmail does not work when selinux is enforced (targeted). If I click "Check Spelling" in squirrelmail's Compose windows, it does not do any spell checking and the system log shows: Feb 16 09:07:25 pippo kernel: audit(1108566445.074:0): avc: denied { search } for pid=7899 exe=/bin/cat name=spool dev=hda3 ino=470497 scontext=user_u:system_r:httpd_sys_script_t tcontext=system_u:object_r:var_spool_t tclass=dir If selinux is disabled, then it works well. Does anybody run fc3 with selinux enforced and run squirrelmail? If yes, please try "Check Spelling". Does it work in your system? If yes, how did you make it working? or how to fix this problem? I appreciate all the help! Hongwei Li
