To make LemonLDAP::NG work with SELinux, you may need to set up some options.
If you are using a RPM distribution and Apache as the web server, you need to install the lemonldap-ng-selinux package to configure SELinux context correctly
yum install lemonldap-ng-selinux
Note
On CentOS 8 and Fedora, this is done automatically
This package will not configure SELinux booleans, please read the next sections to see which booleans you need to enable manually
You need to set the correct context on the cache directory
Deprecated since version 2.0.10: this is now done by the lemonldap-ng-selinux package
semanage fcontext --add -t httpd_cache_t -f a '/var/cache/lemonldap-ng(/.*)?'
restorecon -R /var/cache/lemonldap-ng/
setsebool -P httpd_can_connect_ldap 1
setsebool -P httpd_can_network_connect_db 1
