Configuration backend from File to LDAP error
I have followed the procedure to switch from "File" configuration backend to "OpenLDAP" configuration backend and restarted Apache. But now I have this error and the portal is unusable : "Storable binary image v89.151 more recent than I am (v2.10) at /usr/lib/x86_64-linux-gnu/perl/5.20/Storable.pm line 424, at /usr/share/perl5/Lemonldap/NG/Common/Conf/Serializer.pm line 141."
