-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, there is a typo error in acc_mod.c replace line 222 ({"acc_totag_column", STR_PARAM, &acc_totag_col },) with ({"acc_to_tag_column", STR_PARAM, &acc_totag_col },) this will make modparam acc_to_tag_column work. Alternatively u can use acc_totag_column in openser.cfg as modparam name. regard Helmut
