Drupal Association members fund grants that make connections all over the world.
I have an install that uses LDAPAuth and takes groups from ActiveDrirectory into Drupal as roles as the user logs in (if they didn't exist as such beforehand).
I've got authcache working on my dev box with a user with two roles. However I have >2000 roles in the live setup and I seem to have hit a limit when enabling roles within Authcache. To use it I would need many of them to be enabled for use with Authcache, as the users (students) are in many of these AD groups.
Is there a maximum limit to the number of roles that can be enabled that means I can't use this wonderful module to cache content for my authenticated users? (I started ticking/enabling them all and then realised that it had stopped saving my updates - I was ticking about 50 at a time and saving the changes...)
