I have read in XMPP that in case of XMPP rooms, once a user bookmarks the room , he will automatically rejoin the room on re login. But in my case bookmark is getting stored in server as when I query it back Im able to retrieve it. But rejoining is not happening.
Also for retrieving participants list in a members only private group, members are not able to retrieve admin informations. Is it possible to retrive admin info?
