We have ACS 4.1 running. Everything seems to be (and has been) working fine. But when I want to add a LDAP group mapping I get an error message saying "LDAP Server NOT reachable. Please check the configuration". The ldap authentications are working fine, I just can't add a groupmapping. Where do I start troubleshooting this one?
1. Do we have large number of groups in LDAP or AD structure?
2. Also, does your Admin DN has right to query database?

Also, please download the LDAP browser softerra to fetch the correct information and configure it accordingle.
