system_authservers.php - LDAP default ports are not pre-filled
The LDAP server port field should be pre-filled by default, and change automatically based on the Transport selector. The default TCP port is 389 and the default SSL port is 636.
Example of the expected behavior as shown on 2.2.x:
On 2.3 the port field is empty and changing the Transport option does not have any effect.
