LDAP support for non-standard port LDAP Urls

[Aaron Wells]

This came up from a user asking for help on IRC. They had upgraded their site from Mahara 1.4 to Mahara 1.5 and found that LDAP authentication stopped working. Their LDAP "host URL" field was in this format: ldap://fake-dc1.fake.ac.uk:3268;

In Mahara 1.4, this string would be passed in as the first and only parameter to ldap_connect().

In Mahara 1.5, the code is "smarter" and notices the final colon before the port number 3268. It strips this off of the URL, and passes "ldap://fake-dc1.fake.ac.uk" as the first parameter and "3268" as the second parameter to ldap_connect().

The problem is, if the first parameter to ldap-connect is in "URL style" starting with a protocol ldap:// or ldaps://, ldap_connect() IGNORES the second parameter. And so the port was stripped off, and then ignored, and the connection didn't work.

Making matters worse, the documentation tells people to put a protocol header on the front of their "Host URL".
