Hello I tried the referential integrity plug-in and it worked as expected with single master environment and groupofnames and groupofuniquenames groups. I read the admin guide but there were some things that I did not fully understand: 1. How about multimaster environment, if I have servers A and B and I enable plug-in to server A. When change is done to the server B, server A shoud make deletions ar modifications to the directory. But what if the server A is down for maintenance and user is deleted from server B, what happends? Does the server A do anything when it is started after maintenance? 2. How to enable referential integrity to the memberUid attribute? I have user cn=user,c=fi that has uid=user and that user is added to group example so that there is attribute memberUid=user. When user is deleted, uid should be removed from example group. How to achieve this? I tried to add nsslapd-pluginarg7=memberUid to the plugin but it did not work. I'm testing this with FC4 and FDS 1.0.4.
