I create a new user and assign them to existing groups within the different acl's. The new user is not able to access the db's the way the other user's are able to. In fact, the only way I can get the new user to gain the necesssary access (which is often times, just editor) is to give them separate 'person' entires within the acl for that db. The common denominator seems to the upgrade to 5.0.8...ie, users created after the update cannot gain access if put into existing group memberships.
Something with the way I'm creating the users?
Are the groups somehow 'hardcoded' not to accept any new members?
