LDAP settings reset to version 2.
Testing the LDAP authentification in Moodle 2.0 I found this fact. It's not a problem for me because it's only a test server. Also I don't get a problem with this because my Moodle server also connects with version 2 to the LDAP server running on the same Mac Server. I don't know if the Mac Server also works with version 2?? The documentations says it should be version 3. So it should be version 3 and I set it to 3 in the LDAP auth settings moodle/admin/auth_config.php?auth=ldap .... but everytime I come back to this page I must see version 2.
Another server with Moodle 1.9.9+ does not show this problem with LDAP. I'm using the same LDAP server.
I don't know if this will be a problem for other servers.
