Hi, We are in a process of analyzing different LDAP servers. We have a situation where we have 85K users and at any given point of time 3K users are expected to be online. Will OpenLDAP be a suitable candidate? (We can have a dual processor machine with say 1-2 Gig RAM) Thanks Sac __________________________________ Do you Yahoo!?
