Hello, I am trying to build a similar object to Group object in FIM portal. The new object will reference User objects. I am trying to find how the Member attribute is being used in the group's RCDC, but I dont seem to be able to find Member in the Portal (Portal > Schema Management > All Attributes). Any help would be appreciated.

Hi There, Groups are handled differently in FIM than other objects. There are some special features in the code that allow the dynamic or manual group management to occur. If you go into the schema management, look at the resources and click the "checkbox" to the left of group. Once selected the "Binding" button on the top menu will be active as this will list out the specific bindings for the selected object. (Don't confuse this with the "All Bindings" button which is different). In there, you will see two different membership attributes -> Computed Member and Manually Managed Membership which operate in different ways depending on if you have a criteria based group or a manually managed group. Regardless of what attribute is used in the group object, the "member" attribute is populated (at least the FIM MA thinks so) by using the values stored in those attributes (depending on what type of group membership is being used). If you're looking to modify an RCDC and have manual membership, use the "Manually Managed Membership" grouping which is around line 113 and ends on line 179 in the default Group Edit RCDC. Note the system names for the attributes are "ExplicitMember" and "ComputedMember" are the system names but the MA still sees the membership in the "Member" attribute. (Undercover magic :)) If you wanted to create a simple multi-valued reference attribute to contain members and use a UocIdentityPicker in your RCDC to facilitate the population of this, I would strongly suggest that you name the "Member" attribute something different like prefix it with your company stock ticker as I don't know that the impact would be trying to add a name "Member" attribute (if it even allowed you to do so). Thanks B

Much appreciated, Blain. I kept steering at the Computed and Explicit members and trying to figure how they are tied to Member attribute. Now, it all makes sense. I will report back once I have some further question regarding RCDC.
