WORKAROUND:
Current version does not allow to query SBA/SBS pools directly.
You can work around this issue following below steps:
1) Create following Provisioning policies:
a) To enable user for Lync Server
- Create a Provisioning policy for “edsva-Lync-RegistrarPool” attribute
-‘Lync Server Pool’ -> must be checkbox checked
- Provide available pools name (Enterprise + Branch site Pool)
b) Move User to other Pool
- Create a Provisioning policy for “edsva-Lync-MoveTargetRegistrarPool” attribute;
- ‘Destination Lync Server Pool’ -> must be checkboxes checked
- Provide available pools name (Enterprise + Branch site Pool)
2) Apply above two policies on OU where “Lync User Management” policy is already applied
3) Try performing Lync operations
