Hoping that foswiki will be packaged for Debian soon, I’ve prepared a new package for the LdapContrib Foswiki’s extension, reusing what I had done for the twiki-ldapcontrib package.
This should allow integration of Foswiki on Debian systems using LDAP-stored users and groups.
More details about the package in http://picoforge.int-evry.fr/projects/twldapdeb/.
