Hi.
I've got a system updated from old redhat releases to FC2-3 and now 4.
I've just downloaded selinux-policy-targeted and have been able to fix
most of
my problems with setsebool etc. while in permissive mode. However a few more
difficult issues still intrigues me and I'd love it if someone would
offer some help.
First:
[root@spock ~]# audit2allow -i /var/log/messages -l
allow dovecot_auth_t selinux_config_t:file { getattr read };
allow httpd_sys_script_t var_t:dir getattr;
allow named_t unconfined_t:fifo_file read;
allow smbd_t selinux_config_t:dir search;
allow smbd_t selinux_config_t:file { getattr read };
allow webalizer_t home_root_t:dir search;
allow webalizer_t user_home_dir_t:dir search;
The dovecot-auth problem seems to occur with every new connection to
dovecot:

ino=394549 scontext=root:system_r:dovecot_auth_t
tcontext=system_u:object_r:selinux_config_t tclass=file
The httpd problem appears to be python related. Not sure which of my web
applications is triggering it
(if any). Maybe MoinMoin Wiki but I can't seem to trigger it myself,
maybe a search spider is triggering it.

webalizer is being asked to put it's resulting webpages into a local
users web directory in support of per user usage stat. The users
webfolder has the correct objects set for httpd security.

In addition to this I have a shared folder with 'public' material, files
that I offer to for download/upload. This folder is shared to my users
with ftp as well as samba. Is this even possible to do with selinux?

audit2allow suggests:
allow smbd_t ftpd_anon_t:dir { getattr read search };
Greatful for any tips, hoping to enforce soon!
