SynchronizeGroups
As described in Groups, it is sometimes necessary for a connector to provide group membership information to a group server.
OmniGroupServer might be configured to store group information from a repository with the following settings:
[MyRepository] GroupServerJobType=Connector ConnectorHost=localhost ConnectorPort=1234 ConnectorTask=MyFetchTask
When OmniGroupServer needs to get the latest group membership information for the “MyRepository” repository, it sends a SynchronizeGroups fetch action to the connector listening at localhost:1234.
Before you implement the SynchronizeGroups action, enable the action by updating the features() function on the connector so that it returns Features::synchronize_groups:
Features::feature_type MyConnector::features()
{
return ... | Features::synchronize_groups;
}
To implement the SynchronizeGroups fetch action, a connector implementation must override the synchronizeGroups method in ConnectorBase, as illustrated in this sample code:
void MyConnector::synchronizeGroups(const SynchronizeGroupsTask& task)
{
GroupServer gs = task.groupServer();
gs.addUserMemberOf("Samantha", "Editors");
gs.addUserMemberOf("George", "Editors");
gs.addUserMemberOf("Samantha", "Viewers");
gs.addUserMemberOf("Henry", "Viewers");
gs.finish();
}
The SynchronizeGroupsTask passed in to the synchronizeGroups method has a GroupServer member that allows you to send membership information to the Group Server. In this example the user “Samantha” is a member of the “Editors” group and the “Viewers” group, “George” is a member of the “Editors” group only, and “Henry” is a member of the “Viewers” group only. This information completely replaces any information previously present in the group server [MyRepository] repository.
If you want to modify the information that is stored by the group server, use the method setIncrementalMode before making any other commands.
void MyConnector::synchronizeGroups(const SynchronizeGroupsTask& task)
{
GroupServer gs = task.groupServer();
gs.setIncrementalMode();
gs.addUserMemberOf("Robert", "Viewers");
gs.finish();
}
When the connector has updated the group server with all of the group membership information from the repository, the SynchronizeGroups task is complete.
