rhel selinux question

[Barry Allard]

If someone would be so kind to answer a noob question.  When installing an
apache authentication extension called WebAuth (3.5.4), it works great with
selinux disabled (setenforce 0), but turn on enforcement (setenforce 1),
bam, cant read/write the necessary files.  To selinux, perhaps it looks like
rogue code trying to modify configuration files.

 

Files:

/etc/httpd/conf/webauth/keytab

/etc/httpd/conf/webauth/keyring

/etc/httpd/conf/webauth/service_token_cache

audit2allow says

"allow httpd_t httpd_config_t:dir write;

allow httpd_t httpd_config_t:file write;

allow httpd_t user_home_t:file read;"

but this seems arbitrarily permissive.

 

What would give only access read/write access these three files?  Sorry if
this is off-topic.

 

Running RHEL 5 ("ES", 32-bit) patched.  RTFM'ed already:
http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/selinux-guide/
not much help.
