I'm Using blojsom on my work,and i have seen that the LDAP Authentication Plugin doesn't work with SSL on port 636, it just work on ldap simple without encription.
I have modified the Plugin to allow this,reading a property from the WEB-INF/web.xml file,just like the others properties from LDAP are loaded, it just read if blog-ldap-authorization-use-ssl is true to make a conection using JSSESocketFactory as the socket factory to conections.
It works to me,i have tested it and now is running. I hope it can be on the next release of blojsom ;)
Here is the patch to allow LDAP over SSL.
Note:Please read this[0] to document the process to use SSL sockets, with Certificate Authority (CA) ,the connection works if you have the CA certificate as Trusted
