Description of problem: SELinux is preventing /usr/lib/systemd/systemd-logind from 'read' accesses on the chr_file urandom. ***** Plugin catchall_boolean (47.5 confidence) suggests ****************** If vous souhaitez allow users to resolve user passwd entries directly from ldap rather then using a sssd server Then vous devez en informer SELinux en activant le booléen « authlogin_nsswitch_use_ldap ». Vous pouvez lire la page de manuel « None » pour plus de détails. Do setsebool -P authlogin_nsswitch_use_ldap 1 ***** Plugin catchall_boolean (47.5 confidence) suggests ****************** If vous souhaitez enable reading of urandom for all domains. Then vous devez en informer SELinux en activant le booléen « global_ssp ». Vous pouvez lire la page de manuel « None » pour plus de détails. Do setsebool -P global_ssp 1 ***** Plugin catchall (6.38 confidence) suggests ************************** If vous pensez que systemd-logind devrait être autorisé à accéder read sur urandom chr_file par défaut. Then vous devriez rapporter ceci en tant qu'anomalie. Vous pouvez générer un module de stratégie local pour autoriser cet accès.
