:SELinux is preventing /usr/bin/smbpasswd from 'read' accesses on the file /etc/shadow.
:
:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that smbpasswd should be allowed read access on the shadow 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 smbpasswd /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
