Activiti-explorer 5.15 LDAP integration is throwing an error on task review. It's trying to fetch user picture although no user picture attribute is set in the configuration. (tested with Apache DS)

That is indeed true. It's probably better to return null there. For the moment, you can work around it by extending the LDAPUserManager class and overriding that method, and plugging your custom class in similar to the default LDAP configurator.
