Description Kostas Georgiou 2007-03-14 21:18:06 EDT
cyrus-imapd fails when selinux is in enforcing mode because it fails to read
/etc/krb5.conf

type=AVC msg=audit(1173921130.084:9582): avc:  denied  { getattr } for 
pid=12595 comm="imapd" name="krb5.conf" dev=dm-0 ino=101248
scontext=root:system_r:cyrus_t:s0 tcontext=system_u:object_r:krb5_conf_t:s0
tclass=file
type=SYSCALL msg=audit(1173921130.084:9582): arch=c000003e syscall=4 success=no
exit=-13 a0=5555559db7b0 a1=7fff301a2630 a2=7fff301a2630 a3=555555907a80 items=0

sgid=12 fsgid=12 tty=(none) comm="imapd" exe="/usr/lib/cyrus-imapd/imapd"
subj=root:system_r:cyrus_t:s0 key=(null)
type=AVC_PATH msg=audit(1173921130.084:9582):  path="/etc/krb5.conf"

A module like the following fixes the problem.

module mycyrusimapd 1.0.0;
require {
        class dir search;
        class file { read getattr };
        type cyrus_t;
        type krb5_conf_t;
        role system_r;
};

allow cyrus_t krb5_conf_t:file read;
allow cyrus_t krb5_conf_t:file getattr;
