these rpms are not listed as dependencies in file rpm\lemonldap-ng.spec:
perl-Apache-Session-Browseable perl-Apache-Session-LDAP perl-Apache-Session-NoSQL perl-Apache-Session-Redis
They are needed if you want to use the corresponding base instead of "file", and this is not documented in the doc page for the base.
I saw them in the lemonldap rpm site. any reason for that ? I can find them in the regular repo of centos7.
