Hi,
I'm running two ldap servers (2.4.44) in a 2-Way multi master setup on RHEL 2.6 (glibc 2.12).
Valgrind detects a memory leak every time an entry is deleted a provider.
configure options...
--without-cyrus-sasl \
--disable-bdb \
--disable-hdb \
--enable-ldap \
--enable-mdb \
--enable-constraint
Valgrind output from the provider where the entry was deleted.
.....
