Hi all,

I've got a problem with OpenLdap since I'm trying to insert 1,5 Million of entries into LDAP. OpenLDAP crash with "bdb: malloc: Cannot allocate memory" when approximately 950 000 entries are inserted. My computer got 2GB of RAM and here is my slapd.conf :

# This is the main slapd configuration file. See slapd.conf(5) for more

# info on the configuration options.

What am I doing wrong ?
