Bug 659200

Summary:

SELinux is preventing /bin/su "dac_override" access .

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by su. It is not expected that this access is
required by su and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

#============= user_t ==============
#!!!! The source type 'user_t' can write to a 'dir' of the following types:
# gpg_pinentry_tmp_t, sandbox_file_type, tmp_t, httpd_user_content_t, user_home_dir_t, user_tmpfs_t, screen_var_run_t, mail_spool_t, mqueue_spool_t, tmpfs_t, gpg_agent_tmp_t, sandbox_file_type, user_tmp_t, httpd_user_script_exec_t, user_home_type, user_fonts_t, user_fonts_config_t, nfsd_rw_t, httpd_user_ra_content_t, httpd_user_rw_content_t, user_fonts_cache_t, screen_home_t, sshd_tmp_t, xdm_tmp_t, noxattrfs, dosfs_t

allow user_t admin_home_t:dir { write remove_name };
