:
:*****  Plugin catchall_boolean (47.5 confidence) suggests  *******************
:
:If you want to allow users to login using a sssd server
:Then you must tell SELinux about this by enabling the 'authlogin_nsswitch_use_ldap' boolean.
:Do
:setsebool -P authlogin_nsswitch_use_ldap 1
:
:*****  Plugin catchall_boolean (47.5 confidence) suggests  *******************
:
:If you want to enable reading of urandom for all domains.
:Then you must tell SELinux about this by enabling the 'global_ssp' boolean.
:Do
:setsebool -P global_ssp 1
:
:*****  Plugin catchall (6.38 confidence) suggests  ***************************
:
:If you believe that python should be allowed ioctl access on the urandom chr_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 sealert /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
