Have a cluster with two nodes. When viewing a group on one node, the members show up properly, however when viewing the group on the second node it returns no users.

By turning the cache off in atlassian-user.xml, i.e. changing

<hibernate name="Hibernate Repository" key="hibernateRepository"  description="Hibernate Repository" cache="true"/>

to

<hibernate name="Hibernate Repository" key="hibernateRepository"  description="Hibernate Repository"/>

Then things work normally and both nodes return the users when viewing a group.

Steps to reproduce.

1) Set up a confluence 2 node cluster, check that it works
2) Integrate with LDAP (but leave groups to be managed internally within confluence)
3) Add some of the LDAP users to confluence-users
4) View the group confluence-users on one of the nodes.
5) View the group confluence-users on the other node.

One should return no users, even though the other node displays the users within a group properly.
