"8080" was chosen since it is "two 80's", and also because it is above the restricted well known service port range (ports 1-1023, see below). Its use in a URL requires an explicit "default port override" to request a web browser to connect to port 8080 rather than the http default of port 80.

What is LDAP vs LDAPS?

LDAPS isn't a fundamentally different protocol: it's the same old LDAP, just packaged differently. LDAPS allows for the encryption of LDAP data (which includes user credentials) in transit during any communication with the LDAP server (like a directory bind), thereby protecting against credential theft.
