No, you are not alone, but sadly a remote diagnosis is really hard without knowing about the setup in detail. E.g. you are saying that the create user statement fails. What is the exact error message in the error log? Does it come from LDAP or from OpenACS. If it is from OpenACS, there might be a problem with the code. If it comes from LDAP, most likely soething in the authority section is wrong. But without looking at the values you filled in it is hard to say.
Carl's documentation might help, but you should have gotten the email with the instructions already (I got them from Carl).
In general, we should find an *EASY* way for OpenACS to connect to LDAP directories (Moodle seems to make this considerably easier).
