Okay Guys!

I have solved this problem in the way below.

I create a simple Python 2.7 script that stores each user's posixGroup associations in their pgMemberOf (memberOf) attribute. The purpose is to enable search filters like below...


ldapsearch -x -H 'ldap://' -b 'ou=persons,dc=domain,dc=abc,dc=de' \
    -D 'cn=admin,dc=domain,dc=abc,dc=de' \
    -w 'mySecretValue' \


ldapsearch -x -H '<OPENLDAP_URI>' -b '<PERSONS_OU>,<BASE_DN>' \
    -D '<ADM_USER_DN>' \
    -w '<ADM_USER_PASSWORD>' \

This script is useful for cases where we already have an OpenLDAP installed and we want to make filters available for Posix Groups that already exists in a very simple way and without creating new types of groups. Also useful when unable to install overlays or when this process is too laborious or risky.

The project is in this repository: https://github.com/eduardolucioac/psx-grp-flt

Thanks! =D

I tried, but it's quite difficult to extract the new features :)
Moreover, the new configuration syntax of the dynlist-attrset directive
is quite complicated to learn and interpret. I have a presentiment that
it's really powerful, but it will take some tests to understand the
subtleties and all the possibilities that this offers.

I see and it's a great added !
