Summary:
SELinux is preventing the slapd from using potentially mislabeled files
(/etc/openldap/slapd.pem).
Detailed Description:
[SELinux is in permissive mode, the operation would have been denied but was
permitted due to permissive mode.]
SELinux has denied slapd access to potentially mislabeled file(s)
(/etc/openldap/slapd.pem). This means that SELinux will not allow slapd
to use
these files. It is common for users to edit files in their home
directory or tmp
directories and then move (mv) them to system directories. The problem
is that
the files end up with the wrong file context which confined applications
are not
allowed to access.
Allowing Access:
If you want slapd to access this files, you need to relabel them using
restorecon -v '/etc/openldap/slapd.pem'. You might want to relabel the
entire
directory using restorecon -R -v '/etc/openldap'.
