When configuring an LDAP addressbook with older iOS versions, the phone connects to port 389 for plain text and to port 636 when SSL is enabled. Our secure LDAP service runs on port 636 and before, it was connected. Now, with iOS 6, it no longer connects. It is difficult for me to find out if it is attempting on another port (due to company firewall) but certainly not on 636. Has this been changed? And to what port number?
It appears to be not possible to change to another port number by appending :636 to the server name. When doing this, it simply does not connect anything anymore and it just shows a lookup failed. What gives?
The LDAP setup is very limited anyway. There is no option to specify a BIND DN that I can find, and when entering a username and password it sends the username as a BIND DN, which of course fails because it isn't a syntactically correct BIND DN.
Did anyone get this LDAP client working? With what server? With SSL? What port does it use? Do you have LDAP logs that show how the BIND proceeds?
