ad have AuthenticatedIdentity gfactory, which is what I configured the VO frontend
 to expect.  Not sure why it is using FS to authenticate to the collector though.
 
+Initially, the glideins were failing on startup because the -dir argument to glidein_startup.sh
+had no argument.  We edited the factory xml file and set the directory to '.':
+
+bash-3.2$ vi ../glidein_v1_0.cfg/glideinWMS.xml
+bash-3.2$ ./factory_startup reconfig ../glidein_v1_0.cfg/glideinWMS.xml
+Shutting down glideinWMS factory v1_0@ITB-Stress:          [OK]
+Reconfigured glidein 'v1_0'
+Active entries are:  ITB
+Submit files are in /data1/itb-stress/glideinsubmit/glidein_v1_0
+Reconfiguring the factory                                  [OK]
+Starting glideinWMS factory v1_0@ITB-Stress:               [OK]
+
+
+Then the glideins failed to run because glidein_startup.sh could not find the worker node client software, because the ITB gatekeeper does not point this at a shared location.  I added a few lines to the top of /data1/itb-stress/glideinsubmit/glidein_v1_0/glidein_submit.sh to hack around this problem:
+
+#Dan hack:
+if ! [ -f "${OSG_GRID}" ]; then
+  OSG_GRID=/afs/hep.wisc.edu/osg/wnclient
+fi
+
+I had to remove the gass cache on the CE to make this change take effect!
+
+Then there was a problem with the glidein condor binaries being incompatible with the SL4 machines in CHTC.  To change the binaries used by the glidein:
+
+I unpackd the desired condor tarball and named it
+/data1/itb-stress/condor_versions/7.4.1_x86_rhel3.  I then edited
+glideinsubmit/glidein_v1_0.cfg/glideinWMS.xml.  Remove the existing entry in
+condor_tarballs and replace with this:
+
+<condor_tarball arch="default" os="default" base_dir="/data1/itb-stress/condor_versions/7.4.1_x86_rhel3" />
+
+Then reconfig the factory:
+
+glideinsubmit/glidein_v1_0
+./factory_startup reconfig ../glidein_v1_0.cfg/glideinWMS.xml
+
+Note that this will slightly rewrite the entry we just added to glideinWMS.xml
+to insert the tar_file that it generates.
