*** Bug 831226 has been marked as a duplicate of this bug. *** Stef is this new feature of sssd to store the passwd file in /var/lib/sssd? Dan, this is a dupe of https://bugzilla.redhat.com/show_bug.cgi?id=808297 I'm pretty sure. Except there the content is labeled as sssd_public_t now it is being labeled as sssd_var_lib_t Has passwd moved out of /var/lib/sssd/mc/ Or is /var/lib/sssd/mc/ mislabeled Looks like it must be a labeling issue, then. SSSD deletes and recreates this file on startup. Is it possible that we're missing policy to allow us to create the file as sssd_public_t? Is the file being created in /var/lib/sssd/mc? This directory should be labeled sssd_public_t and then the file would get created with that label. After looking into it further, I finally figured out this is the result of an incorrectly ./configure'd sssd. |
