Many thanks in advance.

ldap_add returned invalid syntax (21)

FAQ lists the following extraneous white space (especially trailing white space) improperly encoded characters (LDAPv3 uses UTF-8 encoded Unicode) empty values (few syntaxes allow empty values)

Not sure how to proceed. Doesn't look like there are any trailing white spaces or empty values.

Also, if I try to login, it seems to know if the correct password is given but then just closes the connection. I'm guessing this may be because all of the ldif file has not been added yet.
