[rancid] clogin error: Error: Couldn't login: <device name>

[Eric Cables]

For some reason rancid-run is reporting in its logs that it is unable to
login to certain devices (MDS switches). I can login to these devices
manually with clogin, but rancid-run continually fails.

log entry:
sdhq-mds-02-04.sege.local clogin error: Error: Couldn't login:
sdhq-mds-02-04.sege.local

[***@light (~)]$ bin/clogin sdhq-mds-02-04.sege.local

Any assistance in troubleshooting this would be nice. Is there a debug mode
I can turn on somewhere?
