Yes, you are right -- there was no avc denials in the audit.log. Now, I set
enforced and try a squirrelmail plugin change_passwd, it creates some avc
denials, and then it works:
# audit2allow -a -M local
******************** IMPORTANT ***********************
To make this policy package active, execute:
semodule -i local.pp
However, it fails when I run:
# semodule -i local.pp
libsepol.check_assertion_helper: assertion on line 0 violated by allow httpd_t
shadow_t:file { read };
libsepol.check_assertions: 1 assertion violations occured
libsemanage.semanage_expand_sandbox: Expand module failed
Actually, this has been an old problem since fc5 linux (not in fc4 or earlier)
-- once set enforced, password cannot be changed from squirrelmail (web site),
modules with "shadow..." cannot be added. Is there anyway to change it? The
reason is simple: my squirrelmail users need to change their password from
within squirrelmail (web site) and I want to set selinux enforced.
BTW, I have policycoreutils-1.34.1-7.fc6 and targeted policy.
I appreciate all the help!
