I am running SElinux in permissive mode. I want to allow samba access to

At setroubleshooters suggestion (see below) - I did the following at a
shell prompt:
Ø *setsebool -P samba_enable_home_dirs=1
*
This seemed to solve the problem. But after a reboot the denials are
back. I assume the boolean is not carried across a reboot.
If my assumption is correct - where is the recommended place to put the:
setsebool -P samba_enable_home_dirs=1
command?
Should I create a local policy module and put it there - or is there
some other recommended place? If anyone can point me to a recommended
procedure ...
Thanks

You've done what you needed to do already - the -P option makes the
boolean persist across reboots.
Summary:
SELinux is preventing the samba daemon from reading users' home
directories.
This summary is actually slightly misleading in this case.
Detailed Description:
[SELinux is in permissive mode, the operation would have been denied but
was
permitted due to permissive mode.]
SELinux has denied the samba daemon access to users' home directories.
Someone
is attempting to access your home directories via your samba daemon. If
you only
setup samba to share non-home directories, this probably signals a
intrusion
attempt. For more information on SELinux integration with samba, look at
the
samba_selinux man page. (man samba_selinux)
Allowing Access:
If you want samba to share home directories you need to turn on the
samba_enable_home_dirs boolean: "setsebool -P samba_enable_home_dirs=1"
The following command will allow this access:
setsebool -P samba_enable_home_dirs=1

These denials are all for the ~/.spamassassin directory and its
contents, not the home directory in general. Browsing the majority of
the home directory would work just fine in enforcing mode.
