RE: Seg Faults with ldapdelete (ITS#53)
I still have the core dumps on a delete. I configured ldap
like so:
LDFLAGS="-L/usr/local/lib" CPPFLAGS="-I/usr/local/include" ./configure
--without-threads --with-ldbm-api=gdbm --prefix=/usr/local/seth
> uname -sprv
OSF1 V4.0 878 alpha
(startup server)
> ldapdelete -h localhost -w xxx -D "xxx" \
-p 393
