Hi.

The auditd logs are full of lines referencing 28756E6B6E6F776E207573657229
, but I can't identify this account

type=USER_LOGIN msg=audit(1364926580.306:249814): user pid=22565 uid=0
auid=4294967295 ses=4294967295 msg='op=login
acct=28756E6B6E6F776E207573657229 exe="/usr/sbin/sshd" hostname=?
addr=127.0.0.1 terminal=ssh res=failed'


What would typically cause this ? There are no other references in any of
the other logs to 28756E6B6E6F776E207573657229 and its to long for our
typical UID / GID .

Thanks

G
