Tim / Peter / all: How can we get 6.6.0 Beta 2 before it's released?
If you manually install Tiki 12.2 on ClearOS 6.x, if all you need is authentication:
* tiki-admin.php?page=login -> General preferences -> Authentication Method: Tiki and LDAP
* tiki-admin.php?page=login -> LDAP ->check "Create user if not in Tiki"
All the other default settings don't need to be changed.
