 | --------------------------------- | --------- | ----------- |
 | `auth-ext.externalId`             | `oauth`   | This will serve as the external ID for users and as the prefix for the external ID of groups created or searched by this extension.  Anything without an external ID is considered internal.  So mismatched external IDs are never considered for anything by this extension. |
 | `auth-ext.tenant`                 |           | A preselected tenant for all operations in this extension.  Only required if there are multiple tenants. |
+| `auth-ext.sync.resyncInMillis`    | `300000`  | To prevent too many sync checks, how long between seeing the EXACT same token should we wait before doing another sync.  The only time this matters is if the user is manually added to or removed from groups in APS by other means.  Or those groups are deleted. |
