I have installed Alfresco using zip distribution. Using Alfresco Share I created new site called CollaborationSite. The site is set up as public. Also I created new user called alfresco1 (and this user can login successfully). Now I'm trying to add new user as site member, but unfortunately no user appear when I enter alfresco1 in user search input. And even admin don't show up when I try to search it. I haven't installed Solr so far, but I think it should not be required to perform user searches. Any advice would be wellcome.
