[otrs] Address book on OTRS 2.2.4+link FAQ to Ticket

Hello Everybody, I have 2 request for the OTRS community : 1) I would know how it's possible to add or create an address book into OTRS ? If yes how can I enable it or create it. And what in the future OTRS will ask LDAP Address book in order to transfer some ticket or other option. 2) I would link automatically an ticket with a OTRS FAQ documentation following the Queue. Someone could say to me how do it. Best Regards, Julian.
