Unable to claim a task when used LDAP identitiy management

[ganeshr]

I have integrated identitiy management succussfully and able to login using ldap and see the ldap groups in Queued tab in Activiti explorer, however claim button is not showing when task is opened in Queued tab and even complete task button is disabled.
I have set group type as 'assignment' for ldap groups. But still the claim buttion is not showing, because of this unable to claim and complete the task.
