1 I am currently trying to make a ldap server which i can use to authenticate users. Sadly a large number of how to's are incomplete and don't work, so after reading alot of how to's and manuals I have got 99.9% of the way. On attempting to authenticate a user it denies the user access with a error from auth.log
