title: ldap_add in php returning "already exists 68" error
body: <p>I just cannot figure out what I'm doing wrong, I've scoured the web for answers but cannot find anything that works. Please can someone look at my code and tell me where I'm going wrong? If I comment out "objectclass" I get "server is unwilling to perform 53", if I change the OU to something silly (the $dn) then I get "Naming Violation", if I mash the keyboard and put in random letters for the user's name I still get "already exists" error even though no parts of the things I'm entering exist. If I add an ldap_mod_replace line in for another CN in the same OU it works fine so I know the connection is working. I've tried without the '[0]' on all except objectclass too (as I've seen in all examples). Company and user info edited obviously.</p>
