+The auth_none plugin is in a separete RPM and not built by default.
+Using the auth_none plugin means that SLURM communications are not 
+authenticated, so you probably do not want to run in this mode of operation 
+except for testing purposes. If you want to build the auth_none RPM then 
+add <i>--with auth_none</i> on the rpmbuild command line or add 
+<i>%_with_auth_none</i> to your ~/rpmmacros file. See the file slurm.spec 
+in the SLURM distribution for a list of other options.
