This is with respect to Stakeholder example given in the video (.mp4)
present on link
https://jazz.net/wiki/bin/view/Main/AttributeValueProviders.The drop
down of stakeholder has 'more' option. We implemented this
functionality in our environment. The working is as below:
1. Added users in Project Area->Overview tab->Member->Add
Users->Added 'Stakeholder' roles to users.
2. The display on the workitem is fine with drop down of Stakeholder
containing only those users who have 'Stakeholder' roles.But
selecting the "More" option in Stakeholder displays all the
users irrespective of having 'stakeholder' role or not because it is
bringing the users from LDAP directory. Is this a limitation of RTC
that on selecting 'More' all the users will be displayed irrespective
of required roles.Please confirm.

Yes, the 'User' presentation will automatically add the 'More...' entry.
I have recently created a presentation that will show your value set
without any automatic additions. This will be in the 3.0 release.

Is there a work item for this that we can track?
