LDAP directory doc needs to cover Studio project interaction

The LDAP setup page at http://doc.nuxeo.com/display/ADMINDOC56/Using+a+LDAP+directory does not make any reference to using LDAP together with Nuxeo Studio projects. But Studio also includes a userDirectory extension in its extensions.xml, and overrides the example ldap-users-directory-config.xml.

So in our case we have to add this line to the ldap-users-directory-config.xml, for the LDAP configuration to work:

<require>studio.extensions.faf-casemanagement-ui</require>

Of course, that will be different for each company using Nuxeo.
