Hi Thierry,

All those issues are originating in memberof code.

==13458== by 0x1189642E: memberof_add_memberof_attr (memberof.c:2934)

The entry added at line 2934 seems to be the culprit.

That's probably what needs freeing.

This bug is a duplicate of https://pagure.io/389-ds-base/issue/49066

The leak is reproducible up to
4973699 Ticket 47982 - Add CI test suite ds_logs

But is fixed by
0e48cdf Ticket 49066 - Memory leaks in server

closing it
