ipa-submit wants to authenticate as the client system when it submits the signing request to the IPA server's XML-RPC service, and it uses the keys in the keytab to obtain the creds that it uses to do so. I think this should be allowed by policy. (We could lock it down further if we built policy for each of the CA-type-specific helpers, but I guess we're not there yet.) One of the AVC's is being cause by coolkey package not including the /var/cache/coolkey directory within its payload. If you simply add this directory, rpm will label the directory correctly, auth_cache_t, which certmonger_t can currently read and write. oops wrong bug. Miroslav please back port cermonger.* to F13, F14, RHEL6. Fixed in selinux-policy-3.9.7-33.fc14 Can an update be created so this can land in F-14? selinux-policy-3.9.7-34.fc14 has been submitted as an update for Fedora 14. https://admin.fedoraproject.org/updates/selinux-policy-3.9.7-34.fc14 selinux-policy-3.9.7-37.fc14 has been submitted as an update for Fedora 14. https://admin.fedoraproject.org/updates/selinux-policy-3.9.7-37.fc14 selinux-policy-3.9.7-37.fc14 has been pushed to the Fedora 14 stable repository. If problems still persist, please make note of it in this bug report. |
