 '''Note: when using Xrootd with DPM, most of the configuration information required for Xrootd, is derived from the DPM configuration. In this context, '''`XROOTD_SERVER_ROLES` must not be defined''' and an explicit definition of `XROOTD_PARAMS` is not required.

+=== Xrootd Federation ===
+
+QWG templates allow to configure one or several Xrootd federations in a Xrootd cluster. Configuring a federation involves two steps:
+ * Declaring federation default parameters in variable `XROOTD_FEDERATION_PARAMS` variable. This variable is a nlist whose keys are the federation identifiers (arbitrary, internal to the configuration description) and whose values are the federation parameters defined as a nlist. Default templates already contains parameters for Atlas (FAX, QWG identifier `atlas`) and CMS (AAA, QWG identifier `cms`) Xrootd federations.
+ * Declaring in the Xrootd cluster configuration (or DPM configuration when using DPM/Xrootd) the federations to activate on the cluster. This is done with variable `XROOTD_FEDERATION_LIST` variable which is a list of federation identifier, matching entries in `XROOTD_FEDERATION_PARAMS`, or a string if there is only one fedederation to configure.
+ 
+Supported configuration parameters that can be configured through `XROOTD_FEDERATION_PARAMS` are:
