LDAP group import - issue with page name format

At the moment I am testing the Active Directory Application including the LDAP User and Group Import.

If I leave most of the parameters at their default (empty) values it is working. If I want to change the Group Page Name Format parameter to ${uid}_Group and start the group import scheduler, I can see that exactly one group with the name ${uid}_Group is being created. It seems that the parameter is not being resolved correctly.

Has anyone experienced the same problem?

Thanks
