That's OK as an ldap_url_parse() OpenLDAP extension, but not as
ldap_url_desc2str() output given to non-OpenLDAP applications.
This is a mess. The ldap: scheme definition has always been broken, and
it certainly does not conform to the basic URI syntax in RFC3986 section
3. In particular, RFC3986 forbids a URI from containing "//" when the
authority component is absent. Looks like RFC4516 should not have been
approved in its current state.
Stupid little things like this make me wonder WTF were they smoking when
they created LDAP. I no longer ask myself wtf they were thinking,
because clearly they weren't...
DNs should have been left in canonical filesystem order, like X.500
tools used. Then we could just treat LDAP URLs like every other
hierarchical URL namespace, with relative paths and all the other
associated conveniences, and use a single generic parser to handle it all.
It's all so damned moronic.
It's almost aggravating enough to make me switch to pure DAP and leave
all of this cruft behind. Mebbe it's time to add a config switch
somewhere to set all of slapd and the libraries to default to DCE/X.500
format DNs, and define a new "xdap" URL scheme to go with it.
