Condor Authentication Error

Got something like this below:
[username@host:~] condor_submit my_job.cmd
Submitting job(s)
ERROR: Failed to connect to local queue manager
AUTHENTICATE:1003:Failed to authenticate with any method
AUTHENTICATE:1004:Failed to authenticate using KERBEROS

Distressing, since I'm not using Kerberos or GSI in a vanilla condor installation.

Solution: I had two condor installations, probably with different versions.  My
.bashrc file set CONDOR_CONFIG to point to installation #1, but I started condor_master
using binaries from installation #2.  Used the same installation consistently and
everything worked.
