I have installed a EVAL licensed Jira 5.2.5 (Windows 32bit installer on 32-bit Windows Server 2008 R2. User directory is connected to "LDAP (MS Active directory) with local Group". I can see all the AD users pulled in to Jira users list. And I can add some LDAP users to the local jira-administrators group. However, when I tried to login to Jira (http://server:8080) with these LDAP users, the login page seems to crash. After I restart Jira service, I can login again with a local Jira admin. What's insteresting is that the user list shows that the LDAP user that tried to login has the seccessful login count increased.
