i have jira, confluence and bamboo installed on a single system. jira is connected to our companys AD-server. bamboo and confluence are connected to jira. when i try to log into one of these apps, it takes over 10 seconds. however, when i test the configured LDAP-queries in apache directory studio it takes less that a second to return a result. syncing the directory in jira is also very fast. only login takes so long. i can't find anything in the logs. any ideas??
