Special characters in vCard closes the session immediately
I use authentication via LDAP/Active Directory with an ejabberd server. Our domain admins had a great idea. They set the title and departement field of my LDAP account to a value like BU Utilities\C&T\Migration+Tools\Tools
I don't know exactly which one of the special characters caused the error but the session is closed right after the vCard is transmitted from the server to the client. I activated the XML console (good debugging tool btw.) and saw the message from the server. I commented out the title and the department field in the mapping configuration of the ejabberd server and after that all things worked like a charm.
