Re: openldap slowness...

[John Von Essen <john@essenz.com>]

With the following, my ldapmodify command is still slow. My ldif file 
has about 5000 entries for users, and 5000 add/modify entries to add 
that user to a cn with a uniquemember attribute. To make sure 
everything I have in LDIF overwrites what in ldap, etc.,. I use the 
following commands:

ldapmodify -c -D "..." -w ... -S outfile -x -r -f ldif
ldapmodify -c -D "..." -w ... -x -a -f outfile

slapd.conf:
