Just an FYI - I recompiled Cyrus SASL 2.1.20 against MIT 1.4 (with mutexes disabled, as recommended by Quanah), and slapd doesn't segfault anymore. Now I guess I need to determine whether or not it will be stable enough to use, of if I should switch to Heimdal libraries, as Quanah also recommended. Does anyone else have good experience one way or the other? Thanks, Greg
