I am looking into using OpenLDAP to manage users and groups for my system. A single group may contain up to 50,000 users. Does the LDAP group membership mechanism suffer any scalability problems at that size?
Not if you configure sortvals - see slapd.conf(5) or slapd-config(5).
One of our partners has a group in their corporate directory whose members comprise every employee in the company, over 380,000 people. Personally I think this is a poor choice of design, but it works fine when properly configured.
