Description of problem:
I typed 'systemctl enable winbind && systemctl start winbind'
SELinux is preventing /usr/sbin/winbindd from 'write' accesses on the directory /var/cache.

*****  Plugin catchall_labels (83.8 confidence) suggests  ********************

If you want to allow winbindd to have write access on the cache directory
Then you need to change the label on /var/cache
Do
# semanage fcontext -a -t FILE_TYPE '/var/cache'
where FILE_TYPE is one of the following: var_log_t, ctdbd_var_lib_t, pcscd_var_run_t, samba_var_t, var_run_t, smbd_var_run_t, samba_etc_t, samba_log_t, user_home_dir_t, winbind_var_run_t, tmp_t, user_tmp_t, auth_cache_t, user_home_t. 
Then execute: 
restorecon -v '/var/cache'


*****  Plugin catchall (17.1 confidence) suggests  ***************************

If you believe that winbindd should be allowed write access on the cache directory 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
