This is definitely a bug; we should not be sending any passwords to any
log file. I've filed Cisco Bug CSCtb52450 ("Passwords in CS-MARS log
files") against CS-MARS so this problem is taken care of. People can
monitor progress of this bug via the Cisco Bug Toolkit on cisco.com at:

http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtb52450

Note that since the bug has just been created it has not yet propagated
to the Cisco Bug Toolkit application, so it is not currently visible
there. It should become visible within the next 24 hours.

Thanks for the report, and please let me know if you have any questions
or concerns.

Cheers,
