I have started getting SE errors with
selinux-policy-targeted-3.5.13-52.fc10.noarch
dovecot-1.1.10-1.fc10.i386

AFAICS there is no boolean to control dovecot, so I assume that it is an inconvenience introduced with some recent update.


Summary:

SELinux is preventing unix_chkpwd (system_chkpwd_t) "write" dovecot_t.

Detailed Description:

[SELinux is in permissive mode, the operation would have been denied but was
permitted due to permissive mode.]

SELinux denied access requested by unix_chkpwd. It is not expected that this
access is required by unix_chkpwd and this access may signal an intrusion
attempt. It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
