[Condor-users] Weird KERBEROS error


I have two systems that I'm trying to join to our pool and unlike the
other 200 or so these two are throwing authentication errors:

4/7 11:01:55 HANDSHAKE: server replied (method = 64)
4/7 11:01:55 AUTHENTICATE: will try to use 64 (KERBEROS)
4/7 11:01:55 KERBEROS: krb5_unparse_name: host/abel.csail.mit.edu@xxxxxxxxxxxxx
4/7 11:01:55 KERBEROS: no user yet determined, will grab up to slash
4/7 11:01:55 KERBEROS: picked user: host
4/7 11:01:55 KERBEROS: remapping 'host' to 'condor'
4/7 11:01:55 unable to open map file /afs/csail.mit.edu/system/i386_linux24/condor/latest-install/etc/condor.kmap, errno 2
4/7 11:01:55 KERBEROS: mapping realm CSAIL.MIT.EDU to domain CSAIL.MIT.EDU.

4/7 11:01:55 AUTH_ERROR: Cannot resolve network address for KDC in requested realm
4/7 11:01:55 condor_write(fd=13 <>,,size=13,timeout=20,flags=0)
4/7 11:01:55 AUTHENTICATE: method 64 (KERBEROS) failed.

>From my reading this means it can't resolve teh KDC, which is a bit
silly.  I can kinit with my principal and kerberized ssh is and has
been working fine on these systems.
