I am looking into using OpenLDAP to manage users and groups for my

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.
I did some testing a while back without sortvals and was able to put
around 90k members in a group before I started running into issues with
adding/modifying the group.
A simple tweak of the bdb lockers in DB_CONFIG allowed me to create a
group with 450k members. The corresponding LDIF was around 20M.
