Accounts created with roles by ldap_integration & ldap_groups do not get assigned to mandatory groups

I've set up ldap_integration and ldap_groups so that users authenticate against an ldap service and get assigned to various roles depending upon values in an ldap attribute. The first time a user logs in their account is created and the roles assigned correctly. However the og_multiple_mandatory_groups_by_role does not assign the user account to any groups associated to those roles. I have to manually edit and save the user account before any groups are assigned.

Is it possible to modify og_multiple_mandatory_groups_by_role so that it will perform group assignments at the time accounts are created by the ldap_integration module? Or alternately, does ldap_integration need to be changed to trigger the group assignment when it creates accounts?
