We are in the experimental stages of implementing LDAP in our Drupal 6 environment, using the LDAP integration module. LDAP is installed and working in our dev environment and now we are looking at different transition plans. We have a fairly substantial user base (couple hundred user in the DB) although realistically we have only a few dozen active users.
My first thought is to go 'cold turkey' and just drop the Users table and ask all users to just start using LDAP for authentication. I tried this in dev, and while authentication worked, some pages would not load, and I'm wondering is this because there is no longer a user associated with these pages?
So along with the specific question above I'm wondering what is the best path for a transition to LDAP on a server with an existing user base? We cannot reliably key off of a username or email to 'sync' the users. That is why I am inclined to start with a clean user table if I can.
