:SELinux is preventing /usr/sbin/winbindd from 'read' accesses on the file /usr/share/samba/codepages/lowcase.dat.
:
:*****  Plugin catchall_labels (83.8 confidence) suggests  ********************
:
:If you want to allow winbindd to have read access on the lowcase.dat file
:Then you need to change the label on /usr/share/samba/codepages/lowcase.dat
:Do
:# semanage fcontext -a -t FILE_TYPE '/usr/share/samba/codepages/lowcase.dat'
:where FILE_TYPE is one of the following: sysfs_t, sssd_public_t, bin_t, cert_t, rpm_script_tmp_t, krb5_keytab_t, ld_so_cache_t, user_tmp_t, sssd_public_t, passwd_file_t, auth_cache_t, machineid_t, krb5_conf_t, puppet_tmp_t, abrt_var_run_t, proc_t, user_cron_spool_t, winbind_log_t, krb5_conf_t, user_home_t, sysctl_crypto_t, etc_runtime_t, smbd_tmp_t, faillog_t, samba_var_t, samba_etc_t, proc_net_t, net_conf_t, chkpwd_exec_t, samba_secrets_t, updpwd_exec_t, winbind_t, ctdbd_var_lib_t, samba_var_t, nmbd_var_run_t, pcscd_var_run_t, smbd_var_run_t, samba_etc_t, samba_log_t, udev_var_run_t, net_conf_t, locale_t, ld_so_t, abrt_t, sysctl_kernel_t, lib_t, man_t, cpu_online_t, afs_cache_t, abrt_helper_exec_t, etc_t, tmpfile, cert_t, puppet_tmp_t, fail2ban_var_lib_t, winbind_var_run_t, winbind_exec_t, textrel_shlib_t. 
:Then execute: 
:restorecon -v '/usr/share/samba/codepages/lowcase.dat'
:
:
:*****  Plugin catchall (17.1 confidence) suggests  ***************************
:
:If you believe that winbindd should be allowed read access on the lowcase.dat file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep winbindd /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
