I have a new Windows Server with FMSA 12v3 on it and a separate Windows server running LDAP. In the FileMaker Admin console under the Database Server, I have clicked the "Security" tab and made sure "FileMaker and external server accounts" client authentication is checked. I go back to the "FileMaker Clients" tab and click on the Configure Directory Service. I put in the LDAP IP, port (389) and Entry Point and it all looks good. I run a test and it says it is successful. But when I go to a FileMaker database, it will not authenticate to this LDAP Server. To test things out, I created an account on the same server that FMSA is on with a group name I was using for authentication. The authentication works just fine through the local server's directory service. Can anyone think of what I am doing wrong in pointing to the external LDAP server for authentication even though the test says it is successful? Any suggestions would be appreciated. Thanks in advance!
