Open Release Management Client and select Administration tab. Select Manage TFS.
Select New to add a new TFS Connection and specify the TFS Server.
Once all information is filled out, select ‘Verify’. A common error that occurs is the Access Denied error.
Access Denied: ReleaseUser needs the following permission(s) to perform this action: Make requests on behalf of others.
This error occurs if the user being used does not have the right permissions in TFS. To configure the permissions, a user or a windows group must be added to the Project Collection Administrators group and granted Make requests on behalf of others permission.
Add User or Windows Group to Project Collection Administrators.
Grant Make requests on behalf of others permission to the user or windows group.
Once above steps are completed, the connection can be verified and saved.
