One of our client is having trouble with his LDAP module ever since they migrated to AD 2008. Two of their apps seem to remove the LDAP group mappings at random? I have not been able to fully analyse this problem just yet but i was wondering if anyone else has ever encountered this problem before? One thing i did find is that one app seems to have no problem at all. However that app is running on 2.5.7.1 compared to 2.5.6 that the two are running on with problems. All 3 apps make use of the newest ldap module 2.1.1
