[Condor-users] condor host does not see worker node

[Ilya Narsky <narsky@xxxxxxxxxxxxxxx>]

I installed condor 6.8.1 on our Rocks 3 ITB cluster (a headnode and 1
worker node):

Linux citgrid3.cacr.caltech.edu 2.4.21-32.0.1.EL.cernsmp #1 SMP Thu May 26 
12:29:50 CEST 2005 i686 i686 i386 GNU/Linux

I use the same condor configs that worked successfully on the same cluster
under condor 6.7.20. But now the condor host does not see the worker node.  
condor_status returns only vm's for the headnode. Looking at CollectorLog,
I can see:

11/8 14:44:21 DaemonCore: PERMISSION DENIED to unknown user from host 
<192.168.0.253:46418> for command 0 (UPDATE_STARTD_AD)

11/8 14:44:24 DaemonCore: PERMISSION DENIED to unknown user from host 
<192.168.0.253:46421> for command 0 (UPDATE_STARTD_AD)

where 192.168.0.253 is the worker node ip.

Condor is installed and started as root.

Can anyone advise?     Thanks,  Ilya
