[Samba] phpldapadmin URI

[Ricky Nance]

I removed that config file nearly 2 years ago... The fact is there hasn't
been anyone asking about it until now, and furthermore samba-tool or
windows ADUC do nearly the same thing. Unless you can come up with a way to
test it and a REALLY good use case personally (and my opinion may not be
worth much) I don't see any good reason for Samba to support it. Please
note that I'm not a samba team member, so this may not be their view on the
subject.
