Hi,
I use syncope 2.1.7 I have exported then imported a MasterContent.xml on a new platform. On this new platform, after deployment, I see that every role has dynamic membership set (using GROUP_MEMBERSHIP IN) as expected. Then I add my users (using the REST API) with the right group memberships as it was previously. Finally I log-in with my users just added, but I see that nobody has any role, it seems that role dynamic memberships are not taken into account somehow. This is checked by viewing "members" for every role. No role has a member. In order to workaround this, it seems necessary to "reload" roles by "edit -> finish" on every role. After that, users have their roles as planned. hope it helps Thanks.
