--- Comment #1 from David Coutadeur david.coutadeur@gmail.com --- Hello,
Setting correctly the full module path is a requirement of ppm. It is up to the admin to correctly set this, else the module and OpenLDAP would crash.
For information there is now a man page for ppm, please give a look at: https://github.com/ltb-project/ppm/blob/ppolicy10/ppm.md
The man page has also been included in OpenLDAP master branch, and is likely to be provided in next 2.5.8 version.
